case_images: The radiograph revealed an apparent area of hypotransparency of the femoral head (Fig. 1a) and the ultrasound showed presence of moderate joint effusion. In the 2-3 weeks after childbirth, the patient remained symptomatic and repeated X-ray showing a small lithic zone (2 cm x 2 cm) circumscribed to the internal femoral head (Fig. 1b) and to attain further characterization of the lesion an MRI was performed (Fig. 2).
case_images: Magnetic resonance imaging after conservative treatment with almost complete resolutions of aforementioned findings.

case_images: In February 2014 (20 months after childbirth), she presented a considerable improvement of the complaints, with good mobility/function of the left hip joint, with no need for walking aid, and with a second MRI revealing reduction of intra-articular free fluid and downsizing of the extensive signal change that affected almost the entire left femoral head, which had a size of 1 cm x2 cm (Fig. 3).
