Abstract

|
A magnetic resonance imaging was performed on a 25-years-old male patient who had a stuffy nose, and an extra-axial lesion was detected in the right frontal bone with a welldefined hypotonic border and a mixed signal strength. As the size of the mass increased, and en-bloc resection was performed during the follow-up. The operation results showed dark-brownish turbid fluid with a sludge-like matter surrounded by a capsule. In the histopathology of the tumor, bone trabeculae were infiltrated by extensive hemosiderindeposited macrophages and cholesterol clefts, which suggested an aneurysmal bone cyst. The patient showed a stable course and was later discharged from the hospital. The brain computed tomography performed one month after the operation showed clear findings without tumor recurrence. Herein, we reported one case of aneurysmal bone cyst occurred in the right frontal bone, which was successfully treated by surgical resection.
