True Diverticulum of the Gallbladder in Acute Calculous Cholangitis: A Rare Presentation

Abstract

A true diverticulum is a congenital rare anomaly of the gallbladder and includes all 3 layers of the gallbladder wall. The ultrasound appearance of a true diverticulum of the gallbladder is typical and clinches the diagnosis. This case report describes a 44-year-old male with features of acute calculous cholangitis and a rare presentation of an incidentally detected true gallbladder diverticulum.

Gallbladder Diverticulum as a Rare Disease and a Therapeutic Challenge: A Case Report

“…Clinically, patients with gallbladder diverticula may be asymptomatic or present with symptoms that mimic cholecystitis, such as right upper quadrant pain, nausea, and vomiting [1,4,[7][8][9]. This overlap in symptoms can complicate the diagnostic process.…”

“…Ultrasonography is the first-line imaging modality for diagnosing gallbladder diverticulum due to its accessibility and non-invasiveness [9,10]. However, its sensitivity can be limited, necessitating additional imaging techniques such as CT or magnetic resonance imaging (MRI) to confirm the diagnosis and rule out other pathologies.…”

“…Asymptomatic cases may be managed conservatively with regular follow-up [11]. However, symptomatic patients or those with complications such as recurrent cholecystitis or suspicion of malignancy typically require surgical intervention [6,9]. LC is the preferred surgical approach due to its minimally invasive nature and reduced recovery time compared to open surgery.…”

“…7×109 /L with 49.5% neutrophils. Liver function tests revealed alanine aminotransferase (ALT) at 22 U/L, aspartate aminotransferase (AST) at 19 U/L, alkaline phosphatase (ALP) at 52 U/L, gamma-glutamyl transferase (γ-GT) at 17 U/L, total bilirubin (TBiL) at 12.3 umol/L, direct bilirubin (DBiL) at 2.6 umol/L, and indirect bilirubin (IBiL) at 9.7 umol/L.…”
