Imaging characteristics of meningiomas in Yemen – Impact of Khat abuse

Maleka Alansi

Abstract. Intracranial meningiomas are the most common tumor derived from non-neural epithelial tissues, accounting for 13% to 26% of all intracranial tumors. In Yemen, several epidemiological studies have showed an increasing rate of meningiomas during the last 15-20 years. This can be explained by the influence of specific epidemiological factors (racial, genetic, toxic, etc) as well as, noticeably improved diagnostic imaging. A specific risk factor for Yemeni subpopulation groups is chronic use of Khat (Catha Edulis Forskal, CE ) – an amphetamine-like product, associated with a variety of serious health, social and economic problems. The present study analyzed the imaging characteristics of meningiomas in Yemeni patients, who systemically use CE, compared to those who never consume it.
