Jejunojejunal Intussusception due to Metastatic Melanoma Seven Years after the Primer

Abstract EN

Intestinal intussusception in adults is a rare medical condition accounting for less than 5% of all intussusceptions.

Herein we present a 45-year-old patient with a history of abdominal pain and loss of weight.

CT scan revealed jejunojejunal intussusceptions.

The patient was subjected to exploratory operation and small intestine resection due to a mass causing intestinal intussusception.

Pathology confirmed suspected diagnosis of metastatic melanoma to small intestine secondary to melanoma, 7 years after the initial manifestation.

Postoperative evaluation with 18FDG-PET/CT revealed increased uptake in the thyroid gland.

Subsequent total thyroidectomy revealed severe Hashimoto thyroiditis and no signs of metastasis.

The patient received adjuvant immunotherapy and is healthy with no signs of recurrence 3 years after the initial diagnosis and treatment.
