Fatal Moans and Bones in Crohn’s
Abstract Introduction/Objective Heterotopic mesenteric ossification (HMO) is a rare, reactive condition involving abnormal bone formation within the mesentery. While its etiology is uncertain, reports suggest two possible inciting events - either metaplasia from trauma and/or inflammation or dislodgment of bone fragments from other sites during abdominal surgery. With less than 50 reported cases, there is much unknown about this disease process. Herein, we present a rare, fatal case. Methods/Case Report A 43-year-old man with a history significant for Crohn’s disease status-post multiple abdominal surgeries and with resultant chronic abdominal pain was found unresponsive at home by family with an unknown downtime. He was taken to the local hospital where he was admitted to the Intensive Care Unit. Given a poor prognosis, family transitioned him to comfort care measures and he died shortly thereafter. Autopsy examination revealed a thin man with an ostomy and severe abdominal scarring. Internally, there were multiple aberrant bone fragments within the mesentery which neither perforated the bowel nor caused obstruction and which microscopically appeared to be mature and benign. Ancillary studies were significant severe dehydration. Follow-up conversation with his family revealed that due to debilitating abdominal pain, the decedent had significantly decreased his oral intake and had stopped taking medications to control his high output ostomy. Given the autopsy and investigative findings his death was certified as a natural death caused by dehydration due to complications of Crohn’s disease. Conclusion This is the first reported case of HMO occurring in inflammatory bowel disease. Awareness of this condition is important for clinicians as it can alter management of these patients. Early review and recognition from radiologists and pathologists can potentially improve the morbidity and mortality of this group.
