This case study highlights a rare instance of small bowel intussusception caused by metastasis from a primary cardiac intimal sarcoma. Early diagnosis and surgical resection are crucial for managing this rare malignancy and its complications.

Area of Science:

  • Oncology
  • Vascular Surgery
  • Gastroenterology

Background:

  • Intimal sarcomas are rare malignant mesenchymal tumors originating in the heart and large blood vessels.
  • These tumors can cause vascular obstruction and spread to distant sites, including the lungs (40% of cases) and extrathoracically.
  • Adult intussusception is uncommon, typically caused by malignancy, and necessitates surgical intervention.

Observation:

  • A 50-year-old man presented with bowel obstruction due to intussusception.
  • He had a history of surgically resected primary cardiac intimal sarcoma with subsequent chemotherapy and documented local recurrence.
  • Imaging revealed an ileal intussusception secondary to a metastatic intimal sarcoma.

Findings:

  • Surgical resection of the affected ileal segment revealed a 10 cm intussuscepted tract containing a polypoid mass.

  • Histopathological analysis confirmed the mass as a grade II intimal sarcoma, consistent with the patient's primary cardiac tumor.
  • This case demonstrates intussusception as a rare manifestation of metastatic cardiac intimal sarcoma.

    • Implications:

    • Primary heart tumors often present late and may be incompletely resected, increasing the likelihood of metastatic disease.
    • Small bowel intussusception in adults is rare but frequently associated with malignancy.
    • Prompt surgical resection and thorough histopathological examination are essential for accurate diagnosis and management of such rare presentations.
