Abstract:
A 77-year-old man had rapidly increased intramuscular tuberculous abscess in his left buttock. Radiographs showed a bone defect in the left ischium. Postcontrast CT scanning revealed marginal enhancement. MR imaging showed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. T1-weighted MR images with Gd-DTPA enhancement showed enhancement of the wall. Bone defect and marginal enhancement on postcontrast MR images and on postcontrast CT images are image character of the intramuscular tuberculous abscess.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
