Perforated Jejunal Diverticulitis. Small intestinal diverticula are very rare; their incidence ranges from 0.06 to 1.3%, with a higher prevalence after the 6th decade of life. Among these small intestinal diverticula, duodenal diverticula are more frequent, followed by diverticula of the jejunum and ileum. A jejunal diverticulum is usually asymptomatic; sometimes patients complain of vague chronic symptoms like malabsorption, pain, or nausea that easily lead to misdiagnosis. Complications are rarely reported, only in 10% of patients. We report a unique case of a 70-year-old female who presented with confusion due to sepsis from perforated jejunal diverticulitis, which was successfully managed with initial resuscitation and definitive surgery.
