Atypical Presentation of Chronic Appendicitis With Concurrent Epididymo-Orchitis in a 71-Year-Old Patient: A Case Report and Clinical Implications.

Chronic appendicitis is an uncommon and often overlooked condition that may present with recurrent, nonspecific abdominal pain, leading to significant delays in diagnosis. The clinical manifestations frequently resemble other gastrointestinal or genitourinary disorders, which further complicates recognition and timely management. We present the case of a 71-year-old man with persistent abdominal pain accompanied by testicular discomfort and swelling, an atypical presentation that obscured the underlying etiology. Through careful evaluation and imaging, the diagnosis of chronic appendicitis was established, and definitive surgical management resulted in complete resolution of symptoms. This case underscores the importance of considering chronic appendicitis in patients with persistent abdominal complaints, highlights the diagnostic value of maintaining a broad differential, and reinforces the role of surgical resection in preventing progression and associated complications.
