A Rare Cause of Thigh Pain: Morel-lavallée Lesion

Morel-Lavallée lesion is an unusual clinical entity which was first described by the French surgeon Maurice Morel-Lavallée in 1853. These lesions result from peeling off the surfaces between the fat tissue and the muscular fascia. During this decomposition, the rupture of small vessels may cause an effusion full of necrotic blood, lymph and fat cells. In prolonged cases, these lesions may become increasingly painful, leading to be confused with other diagnosis such as sciatalgia, piriformis syndrome, trochanteric bursitis or soft tissue tumor. Herein, we present a-65-year-old female case who had pain in the right thigh for one year and was referred to our clinic with radicular pain.
