Abstract

Transient osteoporosis of the hip (TOH) associated with pregnancy is a rare, self- limiting skeletal disorder affecting women, usually in the third trimester, which resolves spontaneously within several months postpartum. Magnetic resonance imaging (MRI) is used primarily for early diagnosis and monitoring the disease progression. Early differentiation from more aggressive conditions such as avascular osteonecrosis, septic coxitis, arthritis, osteomyelitis with long-term sequela is essential to avoid unnecessary treatment. Unilateral involvement of TOH is common. To our knowledge, there has been no case with bilateral involvement of TOH during pregnancy in Korea. We report a rare case with bilateral TOH associated with pregnancy.
