Acute Intestinal Infarction Due to Diffuse Jejunoileal and Mesenteric Lipomatosis in a 39-Year-Old Woman

A case report of small intestinal volvulus caused by lipomatosis of the small intestine successfully treated with enterectomy

Small intestinal lipomatosis is a rare condition that presents a diagnostic challenge due to the absence of identifiable clinical symptoms and limitations of small intestine examination methods. Consequently, preoperative diagnosis is difficult and only a limited number of cases have been documented in the scientific literature. Here, we report a rare case of volvulus caused by small intestinal lipomatosis. A 58-year-old female patient was tentatively diagnosed with acute ileus. The whirl sign was detected using abdominal three-dimensional enhanced computed tomography, along with marked local intestinal dilation and multiple irregular fat-like containing lesions. During surgery, abnormal dilation of the small intestine between 80 and 220 cm from the ileocecal valve was detected and the affected intestine displayed a folded and twisted configuration. Examination of the resected intestine showed that the inner wall of the diseased intestinal lumen was covered with more than 100 lipomas of different sizes, the largest of which measured ~8.0 cm in diameter. Based on clinical symptoms alone, it was difficult to identify the cause of intestinal volvulus before surgery. Complete resection of the affected small intestine and subsequent pathological analysis yielded a definitive diagnosis of small intestinal lipomatosis. While small intestinal lipomatosis is a rare condition, prognosis is favorable if diagnosed early and treated appropriately. The application of three-dimensional enhanced computed tomography imaging can aid in accurate diagnosis, while complete resection of the affected small intestine is crucial to improve patient prognosis.

Diffuse Jejunal Lipomatosis and Associated Complications

Small intestinal lipomatosis is a rare condition with a poorly understood epidemiology and pathophysiology. Cases of small intestinal lipomatosis have been documented in multiple countries over the last century, yet little has been published regarding the natural history of this disease. Therapeutic options are largely surgical and based on limited evidence. We report a unique case of diffuse jejunal lipomatosis in a 62-year-old man with complications of small bowel obstruction, small bowel volvulus, jejunal diverticulosis, pneumatosis intestinalis, malnutrition, small intestinal bacterial overgrowth, and intestinal dysmotility developing over a 12-year period.

Confluent Small Bowel Lipomatosis: A Rare Cause of Recurrent Abdominal Pain

Small intestine lipomatosis is rare but may be associated with pain, intussusception, and gastrointestinal bleeding. In this report, we examine the case of a 41-year-old man who had recurrent presentations to the emergency department with non-specific abdominal pain. Preoperative imaging suggested extensive infiltration of small intestine with macroscopic fat. At surgery, extensive and confluent small bowel lipomatosis were seen. The affected ileal segment was resected, and the patient remained symptom-free after surgery. Abdominal lipomatosis is a rare condition which can be completely treated by resection of the affected gut segment but is often unsuspected and difficult to diagnose. In this report, we describe a case with the most extensive lipomatosis on record with more than 70 cm of gut with confluent lipomatosis. Magnetic resonance Enterography (MRE) is a useful non-invasive diagnostic modality, although laparoscopy/laparotomy may be necessary for assessment of the extent of disease. Symptomatic cases should be treated with segmental small bowel resection, which is curative.

Small Intestinal Intussusception Due to Complicated Giant Jejunal Diverticulosis

Background: Jejunal diverticulosis and jejunal lipomatosis are uncommon conditions. Usually asymptomatic, they may cause severe complications in some cases. Intussusception is unusual in adults, but when diagnosed swiftly it can be treated surgically, usually with good outcome. Case presentation: We present a 60-year-old female patient with a history of chronic malnutrition and anemia, complaining of acute abdominal pain, vomiting and diarrhea. Contrast-enhanced abdominal computed tomography (CT) showed intussusception, multiple giant jejunal diverticula and multiple lipomas. The patient underwent urgent surgery, but radical treatment was not possible due to the extent of the diseases. One month later, another surgery was needed due to ileostomy obstruction caused by lipomas. The patient’s condition deteriorated due to malnutrition and concomitant metabolic disorders, which eventually led to her demise. Conclusions: Radical treatment is not always possible in an extensive jejunal disease. Prolonged malnutrition impairs postoperative healing, and therefore surgical or nutritional treatment should be considered in jejunal diverticulosis before the onset of severe complications requiring urgent surgical intervention.
