Olfactory groove meningiomas clinical and therapeutically features a retrospective study
Abstract
Objectives. Descriptive, retrospective study assessing clinical symptomatology, ancillary diagnostic tests, therapeutically options and clinical outcome in the patients admitted with this diagnostic to Bagdasar-Arseni Clinical Emergency Hospital between 2000 and 2004. Method. Cases were included based on the diagnostic codes in the hospital archives and their clinical records were studied retrospectively. Subgroups were defined according to sex and age criteria in order to provide an accurate epidemiological evaluation. Results.20 cases of olfactory groove meningioma were admitted and investigated during the period mentioned above; 14 were female and 6 male (F/M = 2.3/1), between the ages of 46 and 77; mean age was 57.35±9. Ancillary diagnostic tests were used, including imaging techniques: CT, MRI, angio-MRI, corroborated with ophthalmologic examination. 18 patients underwent surgery. Exitus occurred in 2 patients, consecutive to respiratory insufficiency due to persistent pulmonary infections associated with prolonged immobilization. Conclusions. Olfactory groove meningiomas are a relatively rare disease, more frequent in females, 4th and 5th life decade. As symptomatology may be insidious, diagnosis is only achieved when the tumor is already large; frequently over 4 cm. Diagnosis is basically imagistic, allowing assessing dural and boning involvement. Surgical management with complete tumor removal is usually curative.
