A large intracranial tumor that caused macrocrania leading to dystocia was demonstrated by prenatal ultrasound examination. After birth, computerized tomography (CT) confirmed the presence of a giant supratentorial tumor with a large cyst. When the infant was 20 days old, the tumor was radically extirpated. Neuropathological examination revealed an astrocytoma with focal signs of anaplasia showing a macrocyst as well as multiple microcysts resulting from hemorrhages into the tumor. Although no adjuvant radio- or chemotherapy was administered, the child had nearly normal psychomotor development without clinical or CT evidence of tumor recurrence, and is now 3 years old.

In contrast to the numerous publications on supratentorially located tuberculomas, reports on infratentorial tuberculomas, demonstrated by computed tomography, are relatively few in number. Although nowadays precise localization has become possible via computed tomography, a tuberculoma cannot be identified unequivocally by computed tomography. The appearance of tuberculous lesions in CT depends on the extent the lesion has advanced at the time of the investigation and whether or not tuberculostatics have already been administered. In the posterior cranial fossa, brain stem tuberculomas must additionally be distinguished from cerebellar tuberculomas and tuberculous brain abscess from solid tuberculomas. The problem of tuberculous lesions in computed tomography is discussed with reference to a left frontotemporal tuberculoma and a vermis tuberculoma demonstrated by computed tomography and removed surgically.
