Jejunal lymphangioma causing intussusception: An unusual cas
Adult intussusception is rare, and 90% are due to a lead point secondary to a pathologic condition. The present case has been published in the Annals of Medicine & Surgery.

A 70-year-old male patient with multiple pre-existing pathologies such as advanced ADPKD (Autosomal dominant polycystic kidney disease), multiple persistent tubulovillous colon polyps and colon cancer in situ, was hospitalized due to rapid weight loss of 20 lbs, hematemesis, and abdominal pain.

He was subsequently found to have jejunal intussusception caused by two lymphangiomas of the small bowel. The portion of intussuscepted jejunum was resected and final diagnosis on pathology was two jejunal lymphangiomas.

• Intussusception is rare in adults, but should be considered on the differential for abdominal pain until ruled out using a thorough review of the imaging and symptom set.

• Lymphangiomas of the small bowel are rare compared to occurrence in the head and neck, but if found they can cause a lead point through which intussusception can occur.

• The effect of cytogenesis and tumor formation extra-renally in autosomal dominant polycystic kidney disease is poorly understood. Implications for formation of these cysts and tumors outside of the kidneys could explain this incidence of lymphangioma, and possibly his list of multiple other gastrointestinal cancers.
