An Atypical Presentation of Crohn's Disease: A Case Report.

Crohn's disease (CD) is an inflammatory bowel disease affecting any portion of the gastrointestinal tract, usually the terminal ileum and the colon, with clinical manifestations such as diarrhea, fever, and weight loss. Clinical presentation of CD may include complications such as enterovesical fistulas, abscesses, strictures, and perianal disease. CD also classically presents with "skipping lesions," unlike ulcerative colitis (UC), which presents with continuous lesions. It can manifest with a wide range of extra-intestinal symptoms such as pyoderma gangrenosum, aphthous stomatitis, episcleritis, uveitis, and arthritic disease. Such a wide range of presentations leads to diagnostic difficulties, as seen in this case. Treatment modalities include steroids, antibiotics, and surgical removal of affected parts, depending on the extent of the disease. Here, we present a case of a young male who presented with manifestations of mesenteric lymphadenitis and had an intraluminal cecal mass causing obstructive symptoms, and was subsequently diagnosed with CD.
