Large cholesterol granuloma arising from the frontal sinus--case report.
A 59-year-old male presented with a large cholesterol granuloma arising from the frontal sinus manifesting as a large, fluctuated, soft mass in his brow, compressing left eye. Skull radiography showed dilation of the frontal sinus. Computed tomography and magnetic resonance imaging revealed a cystic mass extending into the left orbit and anterior cranial fossa. Gross inspection at the frontal craniotomy showed mucinous, dark green fluid intermingled with shining material. The histological diagnosis was cholesterol granuloma with epithelial lining. Large cholesterol granuloma with facial deformity is always associated with bone and cosmetic problems. Wide opening of the frontal sinus followed by cyst wall removal and plastic repair of the skull is necessary.
