EC Clinical and Medical Case Reports

Avascular necrosis of the talus is a debilitating condition that affects the ankle joint and results from a deficiency in bone vascularization. It is defined as the death of bone tissue due to a disruption in blood circulation, which can result from trauma, compression, or vascular occlusion. It presents with ankle pain and decreased mobility. We present a case of a 36-year-old patient with chronic post-traumatic ankle pain underwent an MRI, revealing a signal abnormality in the talus dome characterized by T1 hypointensity, T2 hyperintensity with fat suppression, surrounded by a serpiginous peripheral halo showing T1 and T2 hypointensity. The diagnosis of osteonecrosis was made based on these radiological findings. Treatment can be medical, involving pain relief and offloading, or surgical, depending on the stage of the disease.
