3 years, Male, history of nasal polyps, tics concerning for possible seizure activity. Brain parenchyma appears within normal limits without evidence of intracranial mass or mass effect. No findings to suggest seizure focus are appreciated. No evidence of cortical dysplasia or gray matter heterotopia. Bilateral hippocampi appear unremarkable. No evidence of prior ischemia or hemorrhage. The ventricles are within normal limits in size and configuration. No extra-axial collections. Major flow-voids are preserved. There is diffuse opacification of the bilateral middle ear cavities and mastoid air cells.Examination of the paranasal sinuses demonstrates moderate opacification of the ethmoid air cells and partially pneumatized maxillary sinuses. Bilateral frontal sinuses and sphenoid sinuses have not yet pneumatized. No discrete polypoid lesion is evident. No discrete polypoid lesion is evident.
1. Brain MRI appears within normal limits without findings to suggest a seizure focus2. Moderate opacification of the partially pneumatized maxillary sinuses and the bilateral anterior and posterior ethmoid air cells, which is nonspecific. No discrete polypoid lesion is evident but can be correlated with direct endoscopic exam.3. Opacification of the bilateral mastoid air cells and middle ear cavities.
