[Sphenoidal pneumosinus dilatans: a case report (author's transl)].
Pneumosinus dilatans is an abnormal dilatation of a paranasal cavity containing air only. The case described here can be added to the 51 cases in the literature. Various pathogenetic theories have been proposed: mucocele, intrasinus hypertension, inflammation, endocrine disorder. The authors suggest that this pathological form is the result of overextension of a normal process in the morphogenesis of the sinuses. The symptomatology depends on the location and on the rate of onset of the dilatation.
