Unusually Located Pseudoaneurysms: Superficial Palmar Arc and Superficial Temporal Artery

Peripheral pseudoaneurysms mostly occur owing to diagnostic catheterization but rarely owing to blunt or penetrating trauma, infection, or recurrent microtrauma. They appear as a soft pulsatile mass. Complications may occur owing to rupture or distal embolization. Doppler ultrasound and computed tomography are the imaging techniques used in diagnosis. Endovascular interventions and surgery are among the treatment options. In this report, we present two unusually located pseudoaneurysms, one in the superficial palmar arch following penetrating trauma and another in the superficial temporal artery following blunt trauma
