Heterotopic mesenteric ossification: a report of two cases.

Area of Science:

• Gastroenterology
• Surgical Pathology
• Radiology

Background:

• Heterotopic mesenteric ossification (HMO) is a rare condition characterized by abnormal bone formation in the mesentery.
• Approximately 75 cases of HMO have been reported globally, indicating its rarity.

Purpose of the Study:

• To present two distinct cases of Heterotopic Mesenteric Ossification (HMO).
• To discuss the diagnostic features and potential management strategies for HMO.

Main Methods:

• Case report analysis of two patients diagnosed with HMO.
• Review of clinical presentations, imaging findings (CT scan, esophagogram), and surgical resection pathology.

Main Results:

• The first case involved a 39-year-old male with an apple core lesion causing small bowel obstruction.
• The second case involved a 36-year-old female presenting with weakness and emesis post-gastric sleeve resection, showing esophageal kinking.

Conclusions:

• HMO diagnosis can be challenging, requiring integration of clinical, radiological, and pathological findings.
• Conservative management is preferred to avoid further ossification and potential surgical complications.
