Knowledge of the evolution of contrast enhancement patterns on postoperative MR images of the brain can help in differentiating benign from neoplastic changes.

The authors present a case of giant cell tumor of the tendon sheath (GCTTS) in the cervical spine, not previously described in the radiologic literature. Diagnostic imaging includes plain film radiographs, bone scintigraphy, CT, and MRI. Only one case of tenosynovial giant cell tumor of the cervical spine has been reported. The radiological features of this tumor are described along with a brief review of GCTTS.

Intestinal obstruction proximal to a transition zone without an interposed physical barrier usually indicates Hirschsprung disease. The authors report one case of focal small bowel muscular thinning just distal to a transition zone that produced clinical and radiographic findings that simulated long-segment Hirschsprung disease in a 2-day-old infant.
