Proximal focal femoral deficiency (PFFD) is a rare congenital skeletal abnormality characterised by the partial absence of the proximal femoral segment with shortening of the entire lower extremity. It typically presents as a shortened thigh, which is flexed, externally rotated and abducted. Some other skeletal anomalies, especially fibular hemimelia, usually accompany the disorder. The diagnosis of PFFD is made in early childhood and based mainly on conventional radiography. However, the radiographic appearance of the disease evolves as the child grows. In addition, treatment procedures applied to the child affect the radiographic presentation of the disease in adulthood. Almost all cases of PFFD reported to date are in young children and in the current literature, there is a paucity of radiographic images of PFFD in mature skeleton. The aim of this case report is to present the radiographic appearance of PFFD in an adult patient and to increase awareness among radiologists about this disease.
