A Six- Year Review of Meningioma in Rasht Poorsina Hospital

Meningiomas are usually slow growing and benign neoplasms that arise from the intracranial and spinal meninges and their dural extensions. They constitue about 20% of all central nervous system neoplasms.

The objective of this study was to gain more insight into some of important characteristics of meningioma in neurological department of the hospital.

We reviewed retrospectively a series of 62 patients operated on for an intracranial meningioma over a period of 6 years (1994-1999). Setting of study was Rasht Poorsina Hospital and medical records were used. Demographic characteristics, age, gender, clinical, pathological, radiological and other important data were investigated and analyzed.

Meningioma represent 19.1% [CI95%: 14.8%-23.3%] of intracranial tumors. Mean age was 49.1  11.7 years. Female/ male ratio was nearly 1.6:1. History of head trauma was seen in 5 (8.1%). Contraceptive pills were used in 23.7% of women. The most common presenting symptom was headache. The majority of tumors originated in convexity of brain. Peritumoral edema was observed in 37 (59.7%) of cases. Fibroblastic tumors were the most common reported pathology. In our series, we did not observed malignant meningioma and/or multiple meningioma.

Findings of this study were consistent with other demographic and clinical studies.
