Schwannomas are derived from Schwann cells, the most common sites being upper extremiteis, trunk, retroperitoneum, head and neck, mediastinum.However they can arise from the gastrointestinal tract too, including the biliary system.We present a case of a 40 year old gentleman, who presented with obstructive jaundice whose computed tomography of the abdomen was suggestive of mass lesion at the porta causing intra hepatic biliary radicle dilatation.And MRCP s/o similar findings with an endosonography s/o hydatid cyst.He underwent local resection with biliary enteric reconstruction and the histopathological examination confirmed a biliary duct schwannoma.On follow at 6 months, the patient is a symptomatic and shows no signs of recurrence.We have also reviewed the literature of biliary tract schwannomas.
