Sphenoidal pneumosinus dilatans due to anterior skull base meningiomas - CT and MRI aspects: Report of two new cases and literature review

Neuroradiol J. 2016 Aug;29(4):295-7. doi: 10.1177/1971400916648336. Epub 2016 May 24.

Abstract

We report on two patients disclosing a pneumosinus dilatans (PSD) and an anterior skull base meningioma. Our findings, together with those from the pertinent literature, support the thought that this infrequent anomaly of paranasal sinuses is a useful clue to suspect a concomitant meningioma. Moreover, hypotheses concerning the pathophysiology of PSD are discussed.

Keywords: Pneumosinus dilatans; computed tomography; magnetic resonance imaging; skull base meningiomas.
