A 4-year-old girl with mass in the frontotemporal bone.

摘要

A 4-month-old female infant presented with a growing extracranial mass at the left frontotemporal region. Covered with, intact skin, the lesion measured 3.5 x 3 X 3 cm; it was well-defined, bony-hard in consistency, and fixed to the underlying skull. There were no other abnormal symptoms, and routine laboratory tests were within normal limits. The mass appeared sclerotic on skull film. Computerized tomography scan of the brain showed a homogeneously enhancing expansile bone tumor. The lesion caused widening of the lower part of the left coronal suture, just above die orbital roof. The patient underwent left frontotemporal craniotomy, and the mass was found to involve the frontal and temporal bones, around the inferior limb of the coronal suture, adherent to the underlying dura. The orbital roof and apex were also affected. The lesion was totally resected. The immediate postoperative course was uneventful.
