| ABSTRACT |
|
A 33-month-old girl was admitted to the department of Neurosurgery, Seoul National University Hospital complaining of progressively growing suboccipital mass of 14 months' duration. A round, rubbery, child-fist sized mass was situated at the suboccipital area slightly on the right side from midline. The mass was not tender, pulsatile, and bruits were not audibl. There were no significant neurological abnormalities. Simple skull x-ray showed the huge, blown-out osteolytic lesion at suboccipital area and right retrograde brachial angiogram demonstrated no vascularity within the mass. The thick grayish white, well encapsulated cystic mass was firmly adhered to the adjacent bone and underlying dura, and contained about 30cc of chocolate-like deep brownish red, greasy fluid, and soft grumous brownish materials representing organizing blood clots, and consisted of spongy or honeycombed, coarsely trabeculated architecture. The mass was totally extirpated. The report of biopsy was a typical aneurismal bone cyst. She had uneventful postoperative course. |
