Pregnancy related transient osteoporosis of the hip (PR-TOH) is a rare condition that manifests with sudden pain located in the groin region, anterior thigh and buttocks. It is a benign and in the majority of cases self-limiting disease, related to bone marrow oedema. It occurs during the third trimester of pregnancy or less frequently during the post-partum period. Hip movements are usually restricted by pain and it often becomes a non-obstetric indication for Caesarean delivery. Here, we report a case of unilateral PR-TOH diagnosed by magnetic resonance imaging (MRI) and a literature review.
