Extraneural metastasis of intracranial ependymoma is a rare pathological entity. Thirty one case reports were traced in the review of the literature and we record one of them. The patient was a 19-year-old male in good health until January 1981 when he was admitted to our hospital with deteriorating mental status. Admission work-up revealed bilateral papilledema, 1-hemiparesis and increased intracranial pressure signs including vomiting. CT scan demonstrated significant abnormality of enhanced mass lesion in the r-temporo-parietal area in which a displacement of the midline structure to the left occurred. R-temporo-parietal craniotomy was performed on the admission day. The globular tumor mass occupied the temporo-parietal area and invaded the cortex. Subtotal resection of the tumor and temporal lobectomy was performed. Microscopic examination of the operative specimen revealed a typical ependymoma pattern. For the next two years, he received operations twice, irradiation (total 14, 170 rads) and various chemotherapy. Two months after the fourth craniectomy, examination revealed scalp overlying the burr opening to be very tense and enlarging as if invaded by the tumor. A large mass occupied the right lateral cervical area and chest X-ray disclosed complete opacity on the right. He gradually developed severe cough and sputum and died two months later on January 1, 1984. At autopsy, the result was that tumor had invaded the subarachnoidal space and subcutaneous area. Extraneural metastases were found to be bronchial lymph nodes, C-4 vertebra, r-cervical lymph node. The histological appearance of these tumors obtained at autopsy was identical to the cerebral tumor.(ABSTRACT TRUNCATED AT 250 WORDS)

The role of Positron Emission Tomography (PET) using 18F-fluorodeoxyglucose (FDG) in the management of thyroid cancer is discussed. It is important to ensure that patients are relaxed because uptake of FDG in tense or active muscles in the neck and larynx can be misinterpreted as metastases. The major role for PET is in patients where the stage of disease is uncertain, usually the result of discordant negative 131I scan and a positive serum thyroglobulin (Tg) values. PET identifies the source of Tg production in 50-80% of patients. PET scan can be negative in well differentiated cancers which retain the ability to trap iodine. This can result in a 'flip/flop', with negative PET, positive radio-iodine scan, or positive PET, negative radioiodine scan. PET is also valuable in identifying the source of calcitonin production in patients with medullary thyroid cancer. When focal uptake is seen in the thyroid of patients who are scanned for non thyroidal reasons, the likelihood of primary thyroid cancer is high. In contrast diffuse uptake of FDG in the thyroid is usually the result of auto-immune thyroid disorders.

This case report describes the clinical, ultrasonographic, pathological and histological findings in a two-year-old Swiss Braunvieh cow with granulosa cell tumor and metastases in the abdomen and thorax. The cow was ill and had tachycardia, coughing, increased breath sounds, positive reticular foreign body tests and a tense abdominal wall. Ultrasonography revealed a massive accumulation of hypoechoic fluid in the thorax and abdomen, and abdomino- and thoracocentesis yielded red fluid indicative of abdominal and thoracic haemorrhage. Because of a poor prognosis, the cow was euthanized and examined postmortem. Multiple nodular lesions were seen in the omentum, liver, spleen and lungs. The left ovary was grossly enlarged and nodular in appearance. Histological examination of the lesions revealed granulosa cell tumour of the left ovary and metastases in the omentum, liver, spleen and lungs.
