BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2015-212670 DESCRIPTION A 21-year-old Japanese woman developed acute onset of persistent epigastric pain and nausea, and presented to the emergency department 12 h after the onset of symptoms. There was no significant medical history, nor was there allergy, significant family history, recent travel or trauma, and she had not undergone any particular change in eating habits. On examination, she was in acute distress; the blood pressure was 124/75 mm Hg, pulse 90 bpm, respiration 20 breaths/min and temperature 37.4°C. The abdomen was soft and flat, but with positive Mallet-Guy sign (tenderness of left upper quadrant palpation with the patient lying in a right lateral decubitus position). Peripheral white cell count was 1.5×10/L. Renal and liver functions were normal. A diagnosis of acute pancreatitis was suspected and the patient was started on volume replacement and loxoprofen. However, serum lipase and amylase levels were normal and the CT of the abdomen revealed a high-density lesion behind the pancreas, within the retroperitoneal space (figure 1). On day 4, MR cholangiopancreatography showed an increased signal density of retroperitoneal fat (figure 2). A diagnosis of retroperitoneal panniculitis was considered. The abdominal pain gradually disappeared and white cell count returned to normal (7.8×10/L) on day 4. The patient was discharged on day 7. Although abdominal panniculitis is usually recognised in mesenteric fat tissue, few cases with retroperitoneal panniculitis have been previously reported. While causes of abdominal panniculitis may include infectious, neoplastic or autoimmune diseases, our case was considered to have an idiopathic cause because of the self-limited course.

Mesenteric panniculitis is an inflammatory, chronic, and idiopathic disease that mainly affects the adipose tissue of the mesentery of the small intestine. It is considered as the inflammatory stage of a sclerosing mesenteritis, which can evolve into a third stage called retractable mesenteritis where fibrosis predominates.1 Two cases have been described where mesenteric panniculitis extends in...

There are a variety of fat-containing lesions that can arise in the intraperitoneal cavity and retroperitoneal space. Some of these fat-containing lesions, such as liposarcoma and retroperitoneal teratoma, have to be resected, although resection can be deferred for others, such as adrenal adenoma, myelolipoma, angiomyolipoma, ovarian teratoma, and lipoma, until the lesions become large or sympt...
