Huge solitary gallstone complicated with liver cirrhosis in a middle-aged woman: case report.

BACKGROUND: Gallstones are increasingly becoming a common diagnosis in hospitals across the continents, with predominance in women. Patients suspected of a gallstone disease require thorough evaluation including endoscopic ultrasound, magnetic resonance imaging, or magnetic resonance cholangiography. A delayed or missed diagnosis is associated with serious complications and poor prognosis.

CASE PRESENTATION: A 44-year-old female patient presented with fever, vomiting, hypochondria, and epigastric pain for 10 days. Clinical examination showed jaundice and tenderness at the right hypochondriac region. Blood analysis revealed elevated bilirubin, alkaline phosphatase, and white blood cells. The patient was sent for a computed tomography (CT) scan which showed a grossly enlarged liver about 17.2 cm in length and a hypo-attenuating mass in the gallbladder fossa that enhanced moderately and heterogeneously following intravenous contrast administration. Dilated intrahepatic biliary ducts were also appreciated. Explorative laparotomy was performed and revealed an enlarged, cirrhotic-appearing liver, a thickened gallbladder, and a whitish-yellow gallstone about 3 cm in the largest diameter situated at its neck. No isolated tumour was found.

CLINICAL DISCUSSION: Although gallstone disease is very common, misdiagnosis still occurs especially in low and lower-middle-income countries. Inadequate evaluation and increased utilization of CT in emergency and surgical departments are the contributing factors for a missed diagnosis.

CONCLUSIONS: A missed gallstone disease occurs due to various factors including inappropriate standard operating procedures, which set a CT scan as the first imaging test for all internal conditions. This case report presents the appropriate approach to achieving the diagnosis of a gallstone disease before surgical intervention.
