A pelvic rib or pelvic finger is a benign and unusual congenital entity of hip with a finger or rib like bone formation in soft tissues around pelvis. It is generally asymptomatic and incidentally discovered in a plain radiograph. This is a very rare but not unknown entity.
A 25-year-old male reported to our institution with dull aching pain over right hip and abduction gait, then followed up the radiograph and magnetic resonance imaging, in which there was a osteochondroma like lesion in medial aspect of lesser trochanter of right proximal femur was seen. Surgical excision of the lesion was done and sent for histopathological study in which pelvic rib was confirmed.
The real challenge is diagnosis of this condition with its differentials i.e. heterotrophic ossifications around hip, osteochondroma, post-traumatic ossification, or avulsion injuries in and around hip joint This entity should be in mind of radiologists, orthopedic surgeons, and orthopedic onco-surgeons for differential diagnosis of chronic hip pain to avoid unnecessary investigations and procedures.
盆腔肋骨或盆腔指状骨是一种良性且罕见的髋部先天性病变，在骨盆周围软组织中有指状或肋骨样骨形成。它通常无症状，在X线平片中偶然发现。这是一种非常罕见但并非不为人知的病变。
一名25岁男性因右髋部隐痛和外展步态前来我院就诊，随后进行了X线平片和磁共振成像检查，结果显示右股骨近端小转子内侧有一个骨软骨瘤样病变。对该病变进行了手术切除并送去做组织病理学研究，结果证实为盆腔肋骨。
真正的挑战是对这种疾病进行诊断并与其他病症相鉴别，如髋部周围的异位骨化、骨软骨瘤、创伤后骨化或髋关节及其周围的撕脱伤。放射科医生、骨科医生和骨肿瘤外科医生在鉴别诊断慢性髋部疼痛时应考虑到这种病变，以避免不必要的检查和手术。
