Background: Persistent sciatic artery (PSA) is a congenital malformation due to incomplete involution during the embryonic period. Its etiology is unknown, with an estimated incidence of 0.02 - 0.04% in the whole population and a mean age of 60-65 years. Its presentation can be bilateral. It is asymptomatic in most cases and is usually detected accidentally; however, some symptoms may appear, such as claudication, sciatic neuralgia, and pain in the affected limb. It can also manifest as an aneurysmal dilatation or thrombosis that can generate distal embolism with ischemia. Case Report: In this case study, a patient in her 90s with a suspected peripheral arterial disease, which required an angiotomography of the lower limb, showing a superficial femoral artery running to the middle and distal third of the thigh and a vascular structure running in the sciatic neurovascular bundle corresponding to a persistent sciatic artery presenting atherosclerotic changes and extensive occlusion, was presented. The patient's treatment was clinical with dual antiplatelet therapy and prophylactic anticoagulation. This was due to comorbidities and age. Moreover, the PSA occlusion was not critical and did not significantly impact the patient's quality of life. Conclusion: Most patients with this anatomical variant are asymptomatic all their lives, but some of them may present symptoms with serious consequences. It is important to suspect it by clinical presentation and perform diagnostic confirmation by angiotomography. Treatment has yielded excellent results with endovascular techniques. Certain patients only require conservative treatment with anticoagulants and antiplatelet agents.

El dedo (falange) pélvico es una alteración benigna resultante de una anomalía en el desarrollo óseo, donde se encuentra una estructura ósea con apariencia radiológica característica en los tejidos blandos, especialmente en relación con la articulación coxofemoral, aunque puede tener otras localizaciones. Se trata de una entidad benigna que usualmente es asintomática y se encuentra como hallazgo incidental. Conocer su origen y características imaginológicas es de gran importancia para poderla diferenciar de otras lesiones como osificaciones postraumáticas o lesiones por avulsión, que son frecuentes en esta misma localización. Se presentan seis casos con hallazgo incidental de dedo pélvico en diferentes modalidades diagnósticas.
