Findings: • Narrow anterior choana/nares with abnormal “waist” like shape of the maxillary spines and medial angulation of the nasal walls • Central mega incisor
Hx: Pyriform aperture stenosis • Other midline anomalies are common such as holoprosencephaly and central megaincisor Normal nasal cavity for comparison (walls of max sinuses and septum are parallel, not funnel shaped)
Findings: • Defect in between nasal bone and frontal bone • Brain bulges through the defect
Dx: Nasofrontal encephalocele • Congenital extension of brain through skull at the Glabella (should never biopsy this mass) • Treated surgically
Findings: • Well defined area left medial canthus with minimal peripheral enhancement of the wall • Lt mass in nose • Lt soft tissue swelling preseptal
Dx: Dacrocystitis • Needs prophylactic antibiotics and definitive therapy somewhat urgently to prevent infection and nasolacrimal duct damage
Findings: • Well defined area right medial canthus with minimal peripheral enhancement of the wall and fluid level • Rt mass in nose • Rt soft tissue swelling preseptal
Dx: Dacrocystocele • Well defined area right medial canthus with minimal peripheral enhancement of the wall and fluid level • Rt mass in nose • Rt soft tissue swelling preseptal
Findings • Sublingual fluid with cellulitis/inflammation
Findings • Enhancing left parotid with tiny foci of low density; rt is normal; no calcifications a
