Three patients with intracranial tuberculomas with unusual features.

Three patients with verified intracranial tuberculomas are reported. One patient presented with attacks of hydrocephalus initially diagnosed erroneously as migraine, another had multiple tuberculomas and a fourth tuberculoma became apparent during treatment with antituberculous therapy. The third patient presented with a frontal lobe syndrome and the postoperative recovery was complicated by the development of hyperosmolar non-ketotic, non-acidotic diabetic pre-coma. Although there are no pathognomonic symptoms, signs, or radiological appearances of intracranial tuberculomas, a high index of suspicion should always be entertained during the investigation of non-European immigrants.
