A Textiloma on the Pterion : A Rarely Occurred Craniotomy Complication
A 64-year-old woman complained of a painful expansion in the temporal region that she had first noticed five months previously. This patient underwent left pterional craniotomy 8 years earlier for a ruptured aneurysm. There were no complications at the time of her operation. On examination, a well-circumscribed, firm, raised scalp mass at the area of previous craniotomy was defined. Computed tomography (CT) showed a tomb-like isodense lesion having a moderate enhancement under the musculo-cutaneous flap (). Thus, a second surgery was performed. A piece of gauze encapsulated by a large amount of granulation tissue was found at the layer between temporalis muscle and dura through surgical defect of calvarium (). Histopathological study confirmed cotton fibers surrounded by a granulomatous foreign body reaction (). She continued to do well after wound revision.
