A case report of acute gangrenous cholecystitis presenting as right lower quadrant abdominal pain

This rare case highlights that AGC should be considered in patients with right lower quadrant pain, even in those without the classic right upper quadrant symptoms. Timely imaging (ultrasound, computed tomography), paracentesis with fluid amylase/lipase testing, and early laparoscopic exploration are essential for early diagnosis and intervention to improve the outcomes. This case aims to enhance the awareness of atypical presentations of AGC and aid early diagnosis.
