Concomitant lipoma arborescens and synovial osteochondromatosis of the knee.

Intra-articular masses are not a rare finding in routine imaging. This is particularly true in patients with underlying joint diseases such as degenerative arthritis. Nevertheless, concomitant presentation is rather uncommon in imaging studies. The authors report an unusual concomitant lipoma arborescens and synovial osteochondromatosis (which has not previously been reported in the literature to the best of the authors' knowledge) in a man in his 60 s with a long-standing history of knee osteoarthritis. In this case presentation, we review the differential diagnosis for noninfectious synovial proliferative disorders presenting as intra-articular masses, their potential association with underlying joint pathology, and discuss the key imaging features and appropriate treatment.

A Case Report of Intussusception After Gastric Bypass.

Intussusception is a rare cause of late complication after gastric bypass. We report the case of a 53-year-old woman having a gastric bypass in 2011. The patient presented to the emergency department with abdominal pain and vomiting. The diagnosis of intussusception was made by CT scan. Laparoscopy found an invaginated intestinal segment at the level of the jejuno-jejunal anastomosis without necrosis. Adhesiolysis and revision of the anastomosis were performed. The post-operative course was favorable. The diagnosis of intussusception was made by CT scan.
