Abstract :

Olfactory groove meningiomas (OGMs) take their origin from the criiform plate and front ethmoidal suture in the floor of anterior cranial base. These meningiomas are thought to arise from arachnoid cap cells of arachnoid granulations in this region and comprise 10% of all meningiomas in the ain. OGMs represent 9.8% of all intracranial meningiomas, with a maximum occurrence between the 3rd and 5th decade with an average age of 47 years with a clear female predominance ( F:M ratio 3:1).this is a single center coherent study done in the neurosurgical department in the ghazi al-Haririhospital of specialized surgeries / the medical city/ Baghdad/Iraq, between the years 1990 to 2001 that reviews 29 cases of OGMs presented to this center, their clinical, radiological, pathological, surgical and operative outcome with comparison to other studies done involving the same subject.
