Pneumosinus Dilatans

Abstract

Although the presenting complaint of patients with PD is most commonly aesthetic in nature, a significant percentage may have an associated diagnosis. Health care providers must be able to recognize the condition and carry out the appropriate clinical evaluation to avoid missing an associated diagnosis.

Binasal hemianopia caused by pneumosinus dilatans of the sphenoid sinuses

“…[458] These symptoms include gradual painless visual loss, recurrent transient visual loss, and even sudden visual loss. [4578] Approximately 1 mm of the optic canal wall separates the optic nerve from the sinus cavity. Excessive pneumatization can lead to thinning and gross dehiscence of the canal wall and result in compression of the optic nerve.…”

“…[4] The sphenoid sinus, when involved, has not only the highest rate of associated conditions among all sinuses, but also has the most severely associated conditions. [8] The conditions most commonly associated with PSD of the sphenoid sinus are meningioma, arachnoid cyst, and hydrocephalus. [48] Fortunately, these associated medical conditions were ruled out in our case by neuroimaging.…”

“…[8] The conditions most commonly associated with PSD of the sphenoid sinus are meningioma, arachnoid cyst, and hydrocephalus. [48] Fortunately, these associated medical conditions were ruled out in our case by neuroimaging. It will be necessary to consider the possibility of concomitant conditions in the evaluation of patients with PSD of the sphenoid sinus.…”

Non-axial proptosis secondary to pneumosinus dilatans of the maxillary sinus

“…Pneumosinus dilatans can affect all paranasal sinuses. Most frequently affected sinuses are the frontal sinus (63%), the sphenoid sinuses (24%), and the maxillary sinus (20%) with the ethmoidal sinus being least commonly involved (19%) 5 . The commonest presenting complaint of patients with PD the maxillary sinus is cosmetic in nature.…”

“…The commonest presenting complaint of patients with PD the maxillary sinus is cosmetic in nature. Other complaints including facial pain or pressure (worsen by nose blowing or sneezing), nasal obstruction, otalgia, hearing loss, orbital displacement and proptosis 5, 6, 7. Patients with PD of the maxillary sinus have 56% chance of having associated condition at the time of diagnosis.…”
