Rare case of intra articular lipoma arborescens of hip join

Abstract

Lipoma arborescens is a chronic, slow-growing, intra-articular lesion of benign nature, characterized by villous proliferation of the synovium, with replacement of the sub synovial connective tissue by mature fat cells. We present the case report of a 44-year-old male patient with complaints of right hip pain for 4 years. Patient presented with pain, limp and restriction of range of motion at right hip. Plain radiographs followed by MRI scans revealed intra articular lobulated hyper intense lesion with osteoarthritic changes at the right hip joint. Total hip arthroplasty with simultaneous excision of the lesion was planned and carried out for the patient. The aim of the case report presentation is the inclusion of this rare condition lipoma arborescens as a differential diagnosis in such patients and citing the importance of early diagnosis and prompt treatment for the above disease pathology.
