MR imaging of a rare case of primary central nervous system lymphoma in a 12-year-old boy with headache and seizure is presented. MR imaging showed a mass lesion located in the corpus callosum. Diagnosis was made by stereotactic biopsy. The patient was treated with radiotherapy. Early control MR imaging showed a decrease in tumor size but after 12 months an increase in tumor size was detected.
Two cases with acute myeloblastic leukemia (AML M4-FAB) associated with diabetes insipidus (DI) are presented here. Both patients presented with hyperleucocytosis. One had a white blood cell count (WBC) of 150 x 10(9)/L and the second patient had 200 x 10(9)/L. One of these patients was a 40 year-old male and MRI of the hypophysis showed an infindibuler mass. This patient did not respond to remission induction chemotherapy and reinduction chemotherapy was given. The other patient was a 16-year-old male with a normal CT scan of the head. Both patients had DI with typical clinical and laboratory findings. The first patient died early on during reinduction chemotherapy and the second patient died of intracranial bleeding before induction chemotherapy was given. These findings are consistent with the data in the literature suggesting that the prognosis of AML associated with DI is poor and that these cases generally present with hyperleucocytosis.

A rare case with intradural-extramedullary cysticercosis is presented here. MR imaging with and without gd-DTPA were performed. There were multiple cysts in the basal cistern, cisterna magna, and cervical subarachnoid space which were isointense with cerebrospinal fluid both on T2- and T1-weighted images. Swelling and increased signal intensity in the cord parenchyma were detected on T2-weighted images. Gadolinium enhanced studies showed rim-shaped enhancement in the cysts and irregular, diffuse enhancement in the meninges.
