Tuberculosis (TB) of the Terminal Ileum and Cecum with Ascites
A 24-year-old female presents with abdominal pain, night sweats, and a 25-pound weight loss. CT scan coronal (a, b, and c), axial (b and e), and sagittal views show a thickened and enhancing terminal ileum (pink arrowhead a, magnified in d, and b), a focal stricture (red arrowhead a and d), thickened and enhancing contracted cecum and ascending colon (brown arrowhead b, e, and f) with thickened and indurated pericolic soft tissue and peritoneum (white arrowhead b, c, and e). Loculated ascites is noted alongside the ascending colon (orange asterisk a and d).
Comment:
Findings are consistent with ileo-colitis, and in the appropriate clinical setting, tuberculosis. The differential diagnosis of ileo-colitis includes Crohn?s disease. However, simultaneous continuous involvement of both the ileum and colon without skip areas, as seen in this case, is more characteristic of tuberculosis, while Crohn?s disease typically presents with segmental skip lesions and non-contiguous bowel involvement.

Title: Tuberculosis (TB) of the Terminal Ileum and Cecum with Ascites
A 24-year-old female presents with abdominal pain, night sweats, and a 25-pound weight loss.
CT of the abdomen and pelvis (coronal view) and magnified in the lower image demonstrates thickening and enhancement of the ileocecal wall, loculated ascites in the right lower quadrant (RLQ), and free ascites in the pelvis. Findings in the appropriate clinical setting are consistent with gastrointestinal tuberculosis.
Comment: Gastrointestinal tuberculosis frequently involves the ileocecal region, often presenting with wall thickening, lymphadenopathy, and ascites, which may be loculated or free.

Key Features of Tuberculous Peritonitis:

  • Caused by hematogenous or lymphatic spread of Mycobacterium tuberculosis or direct spread from an adjacent infected structure (like ileocecal TB).
  • Radiologic findings often include:
    • Peritoneal thickening and enhancement
    • Loculated ascites
    • Omental caking due to granulomatous inflammation
    • Lymphadenopathy, often with rim enhancement
  • Pathophysiology: The infection stimulates a granulomatous reaction with exudative ascites and peritoneal fibrosis.

Tuberculosis (TB) of the Terminal Ileum and Cecum with Ascites and Omental Thickening
A 24-year-old female presents with abdominal pain, night sweats, and a 25-pound weight loss.
CT axial (a, c) and coronal (b, d) views reveal ileocolic thickening with transmural involvement, induration of the surrounding fat, and thickening of the peritoneum (a). Image (b) shows free ascites and omental caking anteriorly, which is better visualized in the coronal projections (b and d).
Comment: The findings are consistent with tuberculous peritonitis, most likely due to Mycobacterium bovis, which commonly involves the bowel, particularly the ileocecal region, following ingestion of unpasteurized dairy products. The combination of ileocolic thickening, peritoneal enhancement, omental caking, and ascites supports this diagnosis.

MRE – 8/17/2018
1. Short segment of wall thickening and enhancement of the terminal
ileum and cecal base.
Colonoscopy: Circumferential Ulcers at the cecum with gross deformation of the IC valve. Concern for TB vs. CMV
Mycobacterum tuberculosis complex as well as positive Quantiferon Gamma Testing.
Pathology: TI: Ulceration with severe chronic and acute inflammation, necrosis and caseating granuloma
Cecal Biopsy: Fragments of necrotic tissue with chronic and actue inflammatory cell infiltrate and few poorly developed necrotizing granulomas
Tuberculous Enteritis s/p Treatment with RIPE therapy (6 months)
Follow up
Underwent a colonoscopy with evidence of a structural deformity of the cecum and IC valve stricture but no evidence of active inflammatory bowel disease. Her ileum was biopsied which showed eivdence of ileal mucosa with crypt distortion and branching. The findings were “consistent with quiescent CD. AFB stains were negative.”
