Symptomatic Os Vesalianum Pedis in Young Adult: A Case Report

Os vesalianum pedis is a rare accessory foot ossicle, which is located proximal to the base of the fifth metatarsal bone. This anatomic variant is usually asymptomatic and detected incidentally on routine foot radiographs. However, it can be an infrequent cause of lateral foot pain and rarely become symptomatic following traumatic injuries to the ankle or foot. To date, there are few reported cases of symptomatic os vesalianum pedis described in the literature and most of them were treated surgically. We report a case of symptomatic os vesalianum pedis in a young adult female, which was misdiagnosed initially and managed conservatively with physiotherapy. Patient's symptoms regressed completely after a few sessions of physiotherapy and didn't require surgical intervention. We intended to publish this case to increase the awareness of this rare entity among radiologists and clinicians.
