Intracranial metastasis of hepatic carcinomas: a study of 9 cases within 28 years.

A study was made on nine hepatic carcinomas with intracranial metastases. These cases brought a total number of reported intracranial metametastatic hepatic carcinomas to 32 instances. The secondary intracranial hepatic carcinomas formed a proportion of 1.3 to 2.9 per cent among intracranial metastatic tumors. Nine patients in this series were young with an average age of 37 years. There were five hepatocellular carcinomas and four cholangiocarcinomas. An intracranial secondary hepatocellular carcinoma in a 37-year-old man produced massive intracerebral hemorrhage. Only four cases including the current one have been described as massive intracerebral hemorrhage because of secondary hepatocellular carcinoma. Our case, moreover, had a high level of hematocrits representing a paraneoplastic syndrome.

Acute systemic melioidosis: an autopsy study of six cases.

Autopsy findings of six cases of the acute systemic melioidosis from Siriraj Hospital, Bangkok, Thailand during the years 1977 to 1986 are presented. Five out of six cases had some underlying conditions. Multiple abscesses and multiple organs involvement were the rule. The organs most commonly involved were lung and liver. Three patients had pericardial and one had adrenal gland involvement. Other significant pathological findings were fibrin thrombi (5/6 cases), haemorrhage (6/6 cases), tissue necrosis (4/6 cases) and granular casts in renal tubules (1/6 case). Abscess alone cannot explain the death of patients. Toxaemia, both exotoxins and endotoxin, is the most likely explanation from the death of patients.

Neoplasm of mixed mesenchymal and neuroepithelial origin of the optic nerve.

A case is reported of a 19-year-old male having right proptosis for 4 years because of a mixed meningioma and astrocytoma of the ipsilateral optic nerve. The sheath of this nerve is analogous to the leptomeninges, and neuroglial cells constitute the stroma of the nerve. Both meningioma and astrocytoma therefore can arise primarily in the optic nerve, and they may be combined in the same mass, forming a neoplasm of mixed mesenchymal and neuroepithelial origin.
