Efficiency of the flotation method in the isolation of Penicillium marneffei from seeded soil.

The efficiency of a modified flotation method for the isolation of Penicillium marneffei from soils has been evaluated. About 80% was recovered from sterilized soil freshly seeded with P. marneffei (100 conidia/1.

CT findings of seeding tumors.

From 1981 to 1989 there were 43 from 154 cases of metastatic brain tumors, which seeded along the CSF pathways found in the Department of Radiology, Siriraj Hospital Medical School, Bangkok. These seeding tumors were spread from both primary intracranial (25 cases) and extracranial neoplasms (18 cases). Among the primary intracranial tumors, pineal neoplasm was the most frequent site (48%).

Cutaneous sporotrichosis in Thailand: first reported case.

A case of cutaneous sporotrichosis is reported for the first time in Thailand. The infection occurred in a 33-year-old Thai female who has been in good health and had no history of previous trauma or contact with any animals. Histopathology revealed pseudoepitheliomatous hyperplasia of the epidermis and a combination of granulomatous and pyogenic reactions in the dermis and subcutaneous tissue.

CT diagnosis of cerebral cysticercosis.

CT findings of 132 patients with cerebral cysticercosis were analysed. The most common finding was multiple parenchymal punctate calcifications, accounting for 53 per cent; calcifications mostly scattered in both cerebral hemispheres. The second most common finding was enhancing ring(s) or nodule(s) of about 1 cm in diameter with perifocal edema, about 43 per cent.

Computed tomography in the diagnosis of central nervous system lymphomas.

CT appearances of 13 patients diagnosed as having CNS lymphoma were reviewed. Eight patients were of primary type and 5 patients had secondary CNS involvement. In primary CNS lymphoma, the median age was 62.

CT findings of brain metastases.

In 121 proven cases of intracranial metastases, lung cancer was as high as 48 per cent. Multiple lesions were noted (67.8%) in almost every type of organ source.

Ultrasound diagnosis of Dandy-Walker cyst.

A variety of congenital malformations of the brain can be diagnosed by cranial sonography. Those which alter macroscopic morphology can be recognized and their findings are similar to those seen on computed tomography and pneumoencephalography. The ultrasonic findings in Dandy-Walker cyst are described in this report.
