Insights
Adult intussusception is rare. This case highlights jejunojejunal intussusception caused by metastatic lung cancer, emphasizing the need for thorough investigation in adults presenting with these symptoms.
Area of Science:
- Gastroenterology
- Oncology
- Surgical Pathology
Background:
- Intussusception is common in children but rare in adults.
- Adult intussusception often indicates an underlying pathology, necessitating prompt diagnosis and management.
Observation:
- A 49-year-old male presented with acute jejunojejunal intussusception, characterized by abdominal pain and vomiting.
- Surgical resection revealed metastasis from a primary pulmonary tumor.
Findings:
- Pathological examination confirmed metastatic adenocarcinoma and small cell carcinoma from a right lung primary mass.
- The patient underwent successful pneumonectomy and lymph node dissection for the lung cancer.
Implications:
- This case underscores the importance of considering malignancy in adult intussusception.
- Early diagnosis and multimodal treatment are crucial for favorable outcomes in such cases.
Abstract:
Intussusception is a relatively common disease in pediatric age but it is uncommon in adults. We report a case of a 49-year-old male who presented with an acute jejunojejunal intussusception revealed by abdominal pain and vomiting. He underwent an en bloc resection, and pathological findings concluded to a metastasis of a pulmonary combined small cell carcinoma and adenocarcinoma. A subsequent CT scan revealed the primitive mass of the right lung with no evidence of secondary localization. The biopsy was difficult to perform. The patient underwent a pneumonectomy with lymph node dissection confirming the same diagnosis. He made a good recovery from the surgery, and a postoperative chemotherapy was administrated, and he is in remission until this date.
