Intracranial @entity48 commonly present as a discharging sinus, @entity4 , @entity66 , or @entity733 formation. These can sometimes be found in association with @entity154 . The author presents two original cases of infected posterior fossa dermoid associated with @entity299 ( @entity299 ) that is very rare. The embryologic basis for this unique occurrence is reviewed, and a new hypothesis proposed. Two @entity1 with CHD presented with infected midline posterior fossa dermoid. Excision of the @entity48 with the sinus tract was performed. Postoperative period was uneventful. Both the @entity1 had undergone surgery for congenial @entity299 a few months prior to the present clinical presentation with uneventful recovery. Infected posterior fossa @entity48 without a discharging sinus should prompt a thorough examination to detect CHD. Early diagnosis and timely management results in better outcome.
