Summary Brain metastasis from thymic carcinoma is extremely rare, and there is still no consensus regarding the best management of thymic metastasis to the central nervous system. Here, we report the first-known Australian case. A review of the current literature and the characteristics of thymic tumours with brain metastasis indicate that aggressive management may be able to improve long-term outcomes for these patients. A 49-year-old man presented 2 weeks after thoracotomy for thymic carcinoma resection with a 2-day history of headache, right-sided weakness and expressive dysphasia. CT and MR scans revealed two metastatic brain lesions, one within the left frontal lobe with cystic necrosis and haemorrhage, the other deep in the parietal lobe adjacent to the left ventricle with a lesser degree of haemorrhage. The patient underwent frameless stereotactic craniotomy for excision of the frontal lesion. Histopathology confirmed poorly differentiated thymic carcinoma. Post-operatively his weakness and speech improved dramatically, and he was discharged home within a week, with radiotherapy and chemotherapy to follow. However, he represented with rapidly worsening symptoms and died within a week. Thymic carcinoma is a rare tumour, displaying malignant features clinically and histopathologically with local invasion to adjacent organs. Metastasis is predominantly to lung, bone, liver and kidney, with less predilection for the central nervous system. Treatment for thymic carcinoma is multimodal, but outcome remains poor and life expectancy is very short when brain metastasis with haemorrhage is present. ª 2003 Elsevier Ltd. All rights reserved.

INTRODUCTION Thymic tumours are rare and comprise a wide spectrum of types, with thymoma and lymphoma occurring most frequently. Neoplasms arising from thymic epithelial cells are currently classified as thymoma, invasive thymoma and thymic carcinoma.1 Local invasion to adjacent organs is the usual means of spread, with metastasis, particularly to brain, seldom occurring.2;3 Because of this rarity we report a new case presenting with two haemorrhagic metastases to the brain from proven poorly differentiated thymic carcinoma, then discuss the aggressive behaviour of thymic carcinoma with brain metastases in a review of the literature. CASE REPORT A 49-year-old man presented in July 2002 with a brief history of chest pain, shortness of breath and fatigue. His general examiª 2003 Elsevier Ltd. All rights reserved.

nation was unremarkable apart from being out of breath. Neurological examination was entirely normal. Chest X-ray revealed a right anterior mediastinal mass and massive right pleural effusion with lower lobe collapse (Fig. 1). CT scan confirmed the mass, measuring 10  8  7 cm, to extend from the top of the aortic arch inferiorly to the anterior margin of the heart, with evidence of superior vena caval compression and loss of the mediastinal fat plane, suggesting local invasion (Fig. 2). A chest drain was inserted for pleural effusion, and CT-guided biopsy revealed possible primary thymic carcinoma (WHO type C, Masaoka stage IVa4 ). As thymic carcinoma can be associated with other primary carcinoma, further investigations were carried out looking for other primary tumour or metastasis, which proved to be negative.

Methotrexate/bleomycin/cisplatin chemotherapy was given for 5 months. Post-chemotherapy progress CT scan revealed a significant reduction in tumour size. However, at thoracotomy for resection on 12/12/2002, extensive tumour was found, invading the pleura, aorta and pericardium. A diagnosis of stage IVa according to the Masaoka system was confirmed and histopathology showed a poorly differentiated thymic carcinoma with involvement of the margins (Fig. 3). He was discharged home after an uneventful post-operative course and was planned to receive radiotherapy. A few days before starting radiotherapy to the mediastinum he presented with a two-day history of headache, progressive rightsided weakness, expressive dysphasia and confusion. CT scan of the brain revealed a 5  4.5-cm haemorrhagic lesion within the left frontal lobe surrounded by oedema and causing a significant mass effect. A further 2  2-cm lesion was seen deep in the left parietal region effacing the left lateral ventricle (Fig. 4). Preoperative MR scanning revealed two haemorrhagic lesions with cystic necrosis, a larger frontal and smaller deep parietal lobe (Fig. 5). The patient was offered resection of the frontal lesion, since it was readily amenable to surgery and the cause of his rapidly worsening symptoms. Radiotherapy was planned for management of the smaller deep posterior tumour. At frameless stereotactic craniotomy on 27/12/2002, the tumour appeared soft and haemorrhagic with necrosis in the core; gross tumour removal and evacuation of a 4  4-cm intracerebral haematoma were carried out. Pathological analysis confirmed thymic carcinoma (Fig. 6), and tumour staging was revised to Masaoka IVb. Postoperatively he was well. Speech improved significantly, power returned on the right side and he was able to walk unaided. The patient was discharged home on the 12th post-operative day with radiotherapy planned for the next week. Three days later the patient returned to the Emergency Department with rapidly progressing right sided weakness and further speech problems. A brain CT scan was repeated which showed enlarging left parietal tumour of 4  5 cm with increased mass effect and a new haemorrhagic lesion in the left cerebellar hemisphere. He was admitted for further assessment and management. CT chest showed a large complex mediastinal mass indicating recurrence with rapid growth. After discussion with the family further treatment was discontinued and he died five days later. Journal of Clinical Neuroscience (2004) 11(2)

DISCUSSION Thymoma and lymphoma are the commonest primary thymic neoplasms, but the differential diagnosis should also include germ cell tumours because of their sensitivity to modern therapy.5 Neuroendocrine tumours, also found in the thymus, arise from Kulchitsky cells and vary in malignant potential. The histopathological classification and anatomical staging of primary thymic tumours remain controversial.6;7 Initial classifications identified thymomas and lymphomas, based on the ratio of epithelial to lymphocytic cells,7 and included a lymphoepithelial mixed cell type identified by Masaoka et al.8 In 1977 Shimosato et al.9 proposed that some thymomas be classified as a thymic carcinoma type, and additional subtypes were added subsequently.10 LeGolvan and Abell11 found the 5-year survival of 65% of thymic epithelial tumour patients was related to local invasion rather than to cell type. In 1985 Marino and Muller-Hermelink introduced a Journal of Clinical Neuroscience (2004) 11(2)

classification of thymic epithelial tumours (TETs) according to histologic resemblance of the epithelial tumour cells to normal thymic cortical or medullary cells.12 Medullary and mixed thymomas were considered benign, cortical thymoma or well-differentiated thymic carcinoma were usually invasive and had a high frequency of intrathoracic metastasis. This system was not well accepted because of its poor prognostic ability and its confusing terminology.13;14 In 1999, the WHO published a scheme for thymoma using three categories based on prognosis, tumour epithelial cell morphology and the epithelial cell/lymphocyte ratio.1 Thymic carcinoma (type C) is more likely to metastasise than other types. In 1981 Masaoka developed a staging system for thymic tumours,4 which was subsequently modified15 as follows: Stage I. The tumour is encapsulated, still contained within the thymus and may invade into but not through the capsule.

Fig. 6 Photomicrograph showing large cell malignant tumour infiltrating cerebral tissue. Pleomorphic cells with vesicular nuclear chromatin and prominent nucleoli are present. A high mitotic rate, necrosis and haemorrhage are visible (Haematoxylin & eosin, 400).

Stage II. Tumour invades beyond the capsule into nearby fatty tissue; may be adherent to, but not breaking through, the pleura or pericardium. Stage III. Tumour extends into neighbouring tissues or organs, including pericardium, lungs, main blood vessels. Stage IVa. Tumour spreads widely throughout the pleura and /or pericardium. Stage IVb. Extrathoracic spread. Tumour spreads to distant organs via lymphatic or haematogenous systems. This staging system is considered to be the most important prognostic factor.14 TETs affect men and women nearly equally, with mean ages varying between 49 and 62.7 Thirty to fifty percent of patients are asymptomatic, where the mass is detected during a routine chest X-ray. About 30% of patients present with compression effects on adjacent structures such as lung, trachea or major blood vessels which may cause cough, chest pain, dyspnoea, dysphagia, hoarseness or recurrent chest infection.7;16 One-third present with paraneoplastic syndromes, 5% with red cell aplasia and 5–12% with hypogammaglobulinaemia. Thirty to fifty percent may present with myasthenia gravis, but 15% of patients with myasthenia gravis would have thymoma. Seventeen to twenty eight percent patients with thymoma have other malignancy.17 Thymic carcinoma is an invasive tumour accounting for 6% of all thymic tumours16 Metastases are not uncommon to the regional lymph nodes and/or through haematogenous pathways to distant organs, particularly bone, lung and liver18–21 but rarely to the central nervous system.21–23 Most brain metastases are parenchymal. Extra-axial metastasis is extremely unusual.18 Yamamura et al.22 found 27 documented cases in 1993 of intracranial metastasis from thymic carcinoma. The overall 5-year survival rate for high-grade thymic carcinoma is 15–19%.7;16 Surgery, radiotherapy and chemotherapy are recommended as the most effective treatment for thymic carcinoma.2;3;24 . Hanna et al.5 report that thymic carcinoma are chemotherapy-sensitive tumours with a 30–50 % 5-year survival. Review of the literature reveals the importance of resection of a cerebral lesion in patients with known thymic carcinoma to identify the histopathology.

recommended for better quality of life.21;22;25 Our patient presented after a short symptomatic period and did not display myasthenia gravis or any other primary malignancy on full body screening. His biochemistry showed no abnormalities. Disease progression with the presence of two brain metastases having cystic necrosis and haemorrhagic components indicates the aggressive nature of this patient’s tumour, with only one metastasis amenable to resection. Despite craniotomy, his condition rapidly deteriorated even before radiotherapy could be started. This associates the histologic appearance of this tumour with very poor survival. CONCLUSION Thymic carcinoma is a rare tumour. Review of the literature shows this tumour’s lack of predilection for spread to the brain, and the potential for thymic brain metastases to haemorrhage. The prognosis for patients is grim with very short life expectancy. We believe that the presence of haemorrhage and cystic necrosis on imaging indicate the aggressive nature of tumour in a patient diagnosed with Type C TET. Intensive management is vital to improve quality of life and survival rate for these patients. In our opinion the best therapeutic option is surgical resection with radiotherapy and chemotherapy. Frameless stereotactic craniotomy is recommended for better localisation and safer resection. ACKNOWLEDGEMENTS The authors thank Dr. N.

CASE REPORT A 51-year-old Asian woman presented 3 days after rhinoplasty surgery with drowsiness (GCS 11). The procedure had been uneventful with no periods of hypoxia or hypotension, and she was discharged the following day. According to her relatives, she was relatively withdrawn, drowsy and progressively deteriorating on the morning of presentation. When initially seen she was moving all limbs to command, but she then deteriorated rapidly (GCS 9). A CT head revealed a large cerebellar infarct with secondary hydrocephalus (Fig. 1). She had no significant medical history. The patient was taken to theatre and an external ventricular drain was placed. The patient’s condition improved but she remained at a GCS of 13 and it was apparent that she had bilateral abducens nerve palsies. During her stay in the intensive care unit she demonstrated a tendency to desaturate and an echocardiogram was ordered. There was no evidence of vegetations, but the right ventricle was severly dyskinetic, and a high resolution CT chest was ordered to exclude a significant pulmonary embolus. A large embolus involving the right pulmonary artery (Fig. 2) was identified. There was no evidence of DVT on calf Dopplers. In addition, it was noted on the echocardiogram that there was a patent foramen ovale. As a result of the haemodynamic changes there was significant right to left shunting. The right atrial pressure was 50 mm Hg. The possibility of a paradoxical embolism was raised. It was noted that there was a pelvic mass on examination of the abdomen. CT abdomen revealed a large ovarian mass which was thought to represent an ovarian cancer (Fig. 3). The patient was heparinized and maintained with an APTT of 60–70. A CT angiogram of the head revealed evidence of an infarct in the left PICA region with obstruction of this vessel distally. She remained in the intensive care unit for 2 weeks and required a tracheostomy because she was failing to adequately guard her airway. The patient was transferred to a high dependency unit where she continued to improve. She developed severe per-rectal bleeding which was investigated by colonoscopy. The cause was attributed to haemorrhoids. Anticoagulation was ceased and a caval umbrella was inserted. One month after presentation the right ovarian mass was removed and a modified radical hysterectomy performed. The ovarian malignancy was an adenosquamous carcinoma with no signs of dissemination (grade 1). Histopathologically, there was a question as to whether it has arisen in an area of old scarring secondary to endometriosis. Post operatively the patient had problems with ileus and a prolonged gastric stasis. She required long periods of total parental nutrition and subsequently nasojejª 2003 Elsevier Ltd.
