A case report on 'k cells' - pneumatised suprameatal spine, a peculiar anatomical variation

Suprameatal spine (Spine of Henle) is an important surgical landmark on lateral surface of temporal bone. Several types and dimensions of this anatomical entity have been described in literature. However a pneumatised supremeatal spine has not been described. Presence of such rare, unreported anatomical variation may create a confusion, especially for a novice surgeon. This case report presents a rare anatomical pneumatised variant of supremeatal spine and proposes an eponym 'K cell' for it. The aim of this report is to encourage reporting of such variant more frequently, so that suitable modification in current classification can be done.
