RESUMO
Exhaustive clinicoradiologic and computed tomographic (CT) analysis of 114 cases of spinal tuberculosis seen between January 1983 and January 1989 is presented. The mechanisms of the spinal involvement are reviewed. CT helped to diagnose cases of spinal tuberculosis in their initial stages. Inaccessible fixed areas of spine were seen with ease on axial sections of CT. The extent and anatomic depiction of soft-tissue involvement as depicted on CT helps surgeons choose the appropriate surgical approach, which may affect future spinal stability.

Lipoma of corpus callosum and choroid plexus lipoma are rare developmental anomalies arising as a result of maldifferentiation of primitive meningeal tissue. Two cases are reported along with a brief review of literature. The first case presented with chronic headache, and a large lipoma of corpus callosum associated with choroid plexus lipoma was discovered. The second case had no symptoms before the discovery of corpus callosal lipoma on computed tomography, which was done for a head injury. None of the lipomas showed any calcification.

Accurate pre-operative staging of renal cell carcinoma is necessary to determine the surgical approach and prognosis. The advent of computed tomography has brought about a remarkable improvement in accuracy of pre-operative staging in such cases by non-invasive means. The role of computed tomography in staging of renal cell carcinoma has been evaluated in 28 cases and correlated with clinical and surgical findings.

Computed tomography findings with surgical details are presented in a case of hydatid cyst of posterior mediastinum, a rare site of involvement in echinococcosis infestation. The computed tomography appearance of posterior mediastinal echinococcosis is quite characteristic and can be readily distinguished from other cystic lesions of the mediastinum. Computed tomography provides additional information regarding the involvement of neighboring structures. In this case, computed tomography detected involvement of the descending aorta.
