Case report: abscess of the adductor muscles of the thigh--an unusual complication of Crohn's disease

Gluteal and Presacral Abscess Due to Crohn's Disease with Multiple Fistulas

The abscess is a common complication of Crohn's disease (CD), with the perianal form more frequent than gluteal or presacral which is relatively rare. There are few case reports of gluteal abscess combined with presacral abscess caused by CD and the treatment has not been established. A 21-year-old male was admitted with right buttock and lower back pain with a duration of 3 months. He had a history of CD in the small intestine diagnosed 10 months previously. He had poor compliance and had not returned for follow-up care during the previous 6 months. Abdominopelvic CT indicated newly developed multiple abscess pockets in right gluteal region, including piriformis muscle and presacral space. Additionally, fistula tracts between small bowel loops and presacral space were observed. Patient's CD was moderate activity (273.12 on the Crohn's Disease Activity Index [CDAI]). Treatment was started with piperacillin/ tazobactam antibiotic but patient developed a fever and abscess extent was aggravated. Therefore, surgical incision and drainage was performed and 4 Penrose drains were inserted. Patient's pain and fever were resolved following surgery. Infliximab was then administered for the remaining fistulas. After the induction regimen, multiple fistula tracts improved and patient went into remission (CDAI was -0.12).

Missed presentation of Crohn's disease in a patient with a fistulating thigh abscess: a case report

Background

Musculoskeletal presentations of Crohn's disease are rare and they include psoas abscess, thigh abscesses and in extreme cases septic arthropathy.

Case presentation

Herein, we present a 53 year old gentleman with bilateral thigh fistulae discovered to be a new diagnoses of extra-intestinal Crohn's disease

Conclusion

It is important to consider Crohn's disease in patients that present with unusual or persistent fistulae and to consider this essential when there are atypical organisms present.

CT imaging of colitis

Computed tomography (CT) is widely used to assess patients with nonspecific abdominal pain or who are suspected of having colitis. The authors recommend multidetector CT with oral, rectal, and intravenous contrast material and thin sections, which can accurately demonstrate inflammatory changes in the colonic wall and help assess the extent of disease. In most cases, the final diagnosis of the type of colitis is based on clinical and laboratory data and colonoscopic and biopsy findings, but specific CT features help narrow the differential diagnosis. Ulcerative colitis is distinguished from granulomatous colitis (Crohn disease) in terms of location of involvement, extent and appearance of colonic wall thickening, and type of complications. Ulcerative colitis and Crohn disease (granulomatous colitis) are rarely associated with ascites, which is often seen in infectious, ischemic, and pseudomembranous colitis. Pseudomembranous colitis also demonstrates marked wall thickening and, occasionally, skip areas but is associated with broad-spectrum antibiotic treatment or chemotherapy. Neutropenic colitis is characterized by right-sided colonic and ileal involvement, whereas ischemic colitis is characterized by vascular distribution pattern and history. Diverticulitis is a focal asymmetric process with fascial thickening and inflamed diverticula. Dilatation of a thick-walled appendix with increased enhancement and adjacent stranding suggests appendicitis, but inflammatory changes may extend to the cecum and terminal ileum. Epiploic appendagitis is a focal rim-enhancing area next to the colon, usually without any substantial colonic wall thickening.

[Sciatica secondary to a presacral abscess as the first manifestation of Crohn's disease]

Presacral abscess is a rare musculoskeletal complication of Crohn's disease. The clinical picture is sometimes insidious and a delay in diagnosis may increase morbidity. Abdominal-pelvic computerized axial tomography (CAT) has proven to be very useful in the diagnosis of this entity, which usually requires surgical treatment. We present the case of a 22-year-old man who presented to hospital for colic-type abdominal pain of 6 months' evolution and intermittent episodes of joint pain. The patient also presented mechanical pain in the right gluteus muscle of two weeks' evolution irradiating to the posterior side of the muscle. Complementary investigations confirmed the suspected diagnosis of Crohn's disease and showed presacral abscess. Treatment was surgical.
