Intradural cranial congenital dermal sinuses: diagnosis and management

Excerpt

The authors report on their experience with a series of 15 cranial dermal sinus tracts associated with intradural extension that underwent surgical excision. Ten were located in the posterior and five in the anterior cranial fossa. As expected, the anterior locations were associated with an obvious nasal pit, whereas the posterior locations presented with a more variegated clinical pattern (dimple, lump, or sinus tract). Most patients were diagnosed in their early infancy, although in a few cases, the diagnosis was obtained only at a later stage. Also in our experience [1], these lesions were usually diagnosed in early childhood and only exceptionally later than 3 years of age. Likewise, anatomical distribution was quite similar with about 2/3 of the lesions located in the posterior and 1/3 in the anterior cranial fossa. …
