CEREBRAL SCHISTOSOMIASIS - MR AND CT APPEARANCE

After returning from Africa, a 54-year-old man began to have episodes of headache and nausea, then a cerebral convulsion. Clinical and labor atory findings and response to chemotherapy indicated the diagnosis of cerebral schistosomiasis. Three lesions were seen on CT and MR studie s: two appeared to be subacute intracerebral hematomas, one in the rig ht parietal lobe and one in the frontal lobe; the third lesion, in the cortex of the left occipital robe, appeared to be a cyst. These lesio ns could represent small granulomatous tissue reactions with secondary hemorrhages.
