Venous aneurysm not associated with other cardiovascular disease or trauma is a rare condition. A case is presented of bilateral jugular and mediastinal venous aneurysm, which was detected and depicted to a full extent by means of a blood-pool study with 99mTc -fibrinogen, undertaken because of concurrent thrombocytopenia. The aneurysm was confirmed by subsequent X-ray angiography and surgery. In radioisotopic blood pool study venous aneurysm, unlike arterial or aortic aneurysm, may be filled to the equilibrium state later than the appearance of the cardiac pool.

CT scan of the one hundred and sixteen metastatic brain tumors in 50 patients was reviewed and compared to the previous reports. The most common primary organ was lung (43%) followed by breast (18%), colon (10%) and kidney (6%). Solitary nodule was found in 20 patients (40%). On plain CT scan, tumor nodules were demonstrated as slightly high density in 38 (33%), isodensity in 50 (43%) and slightly low density in 28 (24%). Majority of tumor nodules were present in the corticomedullary junction (82%). Brain edema seen as a peritumoral low density was extensive in comparison with the edema in the glioma of the similar size. On contrast CT scan, ring like enhancement was seen in 41 (35%). Intra-tumoral bleeding was shown in 2 metastatic nodules from choriocarcinoma and in one metastatic nodule from renal cell carcinoma. All 3 cases were proved by surgery or autopsy.

The computed tomography (CT) was performed in 10 cases of neurofibromatosis. The CT scan showed the abnormal findings in 8 cases out of 10. Skull lesions were noted in 3 cases and intracranial tumors were found in 5 among which multiple neoplasms were seen in 3. Although reported cases were not large enough in number, the incidence and variety of the tumors were similar to others reported before CT era.
