Nasofrontal dermoid sinus

Description

A 19-year-old woman presented with recurrent episodes of headache and intermittent caseous discharge from a midline pit near the rhinion, since childhood. There was no fever, nausea, vomiting or seizure. Physical examination revealed a widened nasal bridge and a midline aperture with a protruding hair. Patient's neurological examination was normal. A contrast-enhanced CT scan of the head showed a small hypodense lesion at the anterior basifrontal region. T1-weighted MRI images identified a hyperintense intracranial lesion, which showed suppression with fat suppression sequences. T2-weighted images also revealed a high signal lesion modelling the cerebral parenchyma (figure 1), with a small tract going up to the nasal bridge (figure 2). The patient was diagnosed with a nasofrontal dermoid cyst with the extracranial nasal sinus tract and surgical excision was proposed. The histopathological analysis confirmed the previous diagnosis.
