Traumatic extradural hematomas with delayed development.

After introduction of computerized tomography (CT), we experienced 74 patients with 78 traumatic extradural hematomas. Among these, 16 hematomas were subjected to sequential CT examinations in the early stage after injury. Four hematomas of four patients became enlarged, and another five hematomas of four patients were delayed. Accordingly the delayed extradural hematomas are thought to be less uncommon than previously believed. Three patients with four delayed extradural hematomas of surgical significance are reported, and pathogenesis of the delayed extradural hematoma is discussed.

A case of deep soft tissue leiomyoma: CT and MRI findings.

A 25-year-old man presented with a firm tissue mass of the right elbow and intermittent pain. CT showed a dumbbell-shaped soft tissue mass with foci of dense calcification in the muscular layer of the triceps brachii muscle and subcutaneous tissue. The tumor showed slightly higher signal intensity on T1-weighted images and markedly higher intensity on T2-weighted images compared with the surrounding muscle. Prominent enhancement was present after the intravenous injection of Gd-DTPA. Histopathological examination of the resected specimen revealed a deep soft tissue leiomyoma.
