title: MR image and CT scan of a tuberculous abscess in the gluteus maximus muscle.
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.
