Metástasis ganglionar mesentérica de neoplasia neuroendocrina: una causa infrecuente de obstrucción de intestino delgado

Small intestine neuroendocrine tumors (NET-SI) are relatively rare neoplasms. If encountered, the most common location is the ileum. Symptoms are usually non-specific, delaying the tumors diagnosis. NET-SI are often small in size and can be challenging to recognize on imaging studies. However, they...

If encountered, the most common location is the ileum. Symptoms are usually non-specific, delaying the tumors diagnosis. NET-SI are often small in size and can be challenging to recognize on imaging studies. However, they have a tendency to induce a pronounced fibrotic reaction in the mesentery, often accompanied by large calcified mesenteric adenopathies. In some cases, the fibrotic reaction can produce rare complications, such as intestinal obstruction or vascular congestion with occasional secondary ischemia. This case report presents a 79-year-old male with a partial small bowel obstruction caused by a fibrotic reaction and mesenteric adenopathies of a well-differentiated neuroendocrine tumor of the ileum. The patient also presented multiple peritoneal metastases at diagnosis. Characteristic imaging findings of the tumor, allowed an accurate and early diagnosis. Once the acute episode was resolved, the diagnosis was confirmed with an image guided biopsy.info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.149 n.3 20212021-03-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872021000300464es10.4067/s0034-98872021000300464
