Diagnostic assessments:
Blood work up included complete blood count, serum electrolytes, liver function tests, renal function tests, INR, RCT and Hepatitis surface antigens (Table 1). CT scan was done and it revealed a huge cystic mass in the right upper quadrant extending inferiorly to the right lumbar region, surrounded by a thin enhancing wall on intravenous contrast. It was continuous with common bile duct and was compressing the gall bladder, head of pancreas and the right kidney (Figure 3). There was no focal or diffuse masses seen on the liver and there was no regional lymphadenopathy.
