Abstract
Ollier's disease of the hip bone involving the sacroiliac joint has not yet been reported in the English-language literature in both the mature and immature skeletons. The authors present such a unique case in an adolescent girl that posed a significant diagnostic challenge secondary to the rarity of the lesion and atypical clinical picture.
Highlights
Ollier’s disease is a rare disease consisting of multiple enchondromas, usually metaphyseal, with the most frequent location being the metacarpals, metatarsals, and phalanges of the fingers and toes [1]
Patients with SI joint pain seldom report pain above L5 [10] and most localize their pain to an area close and around the posterior superior iliac spine
The immature skeleton of the SI joint has a more flattened articular surface compared to its adult counterpart, which allows more range of motion and increased risk for SI joint malalignment which may become a pain generator [11]
Summary
Ollier’s disease is a rare disease consisting of multiple enchondromas, usually metaphyseal, with the most frequent location being the metacarpals, metatarsals, and phalanges of the fingers and toes [1]. Flat bone enchondromas such as in the pelvis, ribs, scapula, sternum, or vertebrae have been reported [2]. To the authors’ knowledge this is the first case of enchondromas involving the sacroiliac joint in the English-language literature The patient and her parents were informed and gave consent that data regarding her case will be submitted for publication
