چکیده
Pneumosinus dilatans (PSD) refers to an abnormally enlarged, air-filled paranasal sinus without radiological evidence of localized bone destruction, hyperostosis, or mucous membrane thickening. This disorder has been associated with meningioma, especially optic nerve sheath meningioma, but its pathophysiology remains unclear. Spontaneous pneumocephalus is an exceptional presentation of PSD and, to our knowledge, has never been associated with meningioma.

Complex Frontal Pneumosinus Dilatans Associated with Meningioma: A Report of Two Cases and Associated Literature Review
Introduction Pneumosinus dilatans (PSD) is a rare phenomenon involving the expansion of the paranasal sinuses, without bony destruction or a mass. Previously documented cases have demonstrated simple expansion of a solitary air cell. We present two unique cases of PSD in the presence of meningioma, in which complex new cells developed within the frontal sinus. One of the two patients developed...

Idiopathic expansion of a paranasal sinus containing air and without an associated mass has been termed pneumosinus dilatans [1] . This rare disorder has been known to occur in all the paranasal sinuses, but it most commonly affects the frontal sinus. Clinical symptoms include pain , visual loss, proptosis, galactorrhea, and hypopituitarism [2-4]. Proposed mechanisms of origin include developme...
