Prenatal Sonographic Diagnosis of Asymmetric Fibular Hemimelia with Anteromedial Tibial Bowing: A Case Report

Fibular hemimelia is a rare congenital lower limb deficiency, often characterized by an absent or hypoplastic fibula, tibial bowing, and congenital talipes equinovarus (CTEV). Prenatal detection, enhanced by high-resolution ultrasound and fetal magnetic resonance imaging, enables detailed assessment, genetic evaluation, and parental counseling. We report a case of asymmetric fibular hemimelia with tibial bowing and bilateral CTEV in a fetus of a diabetic mother with negative genetic testing. The severity of the condition guides postnatal management, ranging from limb lengthening procedures to reconstructive surgery or amputation. Early diagnosis and reporting of such cases help inform prognosis, counseling, and surgical planning.
