Intracranial tuberculosis: manifestations on computerized tomography.

Intracranial tuberculosis is often insidious, may be difficult to diagnose clinically, and is neurologically devastating if untreated. The advent of computerized tomography has permitted earlier detection of the structural abnormalities associated with intracranial tuberculosis than was possible with older techniques. Correct radiologic interpretation can heighten the index of suspicion for what is often an overlooked diagnosis and can lead to earlier treatment, with decreased morbidity and mortality. We present four cases that cover the spectrum of abnormalities of intracranial tuberculosis shown by CT.

Ventriculoperitoneal shunt function: evaluation by sonography.

The function of ventriculoperitoneal shunts was evaluated by ultrasonography in 17 patients. In 10 of 15 patients with properly functioning shunts, a small amount of free intraperitoneal fluid was found. However, absence of demonstrable fluid did not reliably indicate shunt malfunction. No asymptomatic patients had large amounts of ascites or loculated fluid collections, both of which were considered pathologic in shunt patients.

Abdominal CSF pseudocyst secondary to ventriculoperitoneal shunt: diagnosis by computed tomography in two cases.

Two cases are presented in which the preoperative diagnosis of abdominal cerebrospinal fluid pseudocyst was made by computed tomography (CT). The collection can be well outlined by this method, and measurement of density values characterizes the contents as a water density; the relationship of portions of the shunt catheter to the pseudocyst can be demonstrated as well. It is suggested that, in a patient with a ventriculoperitoneal shunt who develops abdominal signs or symptoms, CT can provide the definitive diagnosis of this entity.

Computed tomography of tumors of the pineal region.

Eight pathologically proven cases of pineal region tumors examined by computed tomography (CT) were found upon reviewing 11,000 consecutive CT studies at the Massachusetts General Hospital. The CT scan findings of the eight cases are described and related to a pathological classification of pineal tumors.
