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.
