Posterior tibial artery pseudoaneurysms are rare and can occur in the setting of trauma. Endovascular treatment of post-traumatic pseudoaneurysms has become a viable less-invasive method particularly in young patients in whom the presence of collaterals guarantees distal vascularization. We report an unusual case of a 16-year- old patient who sustained blunt trauma to his right lower extremity due to a bicycle injury and developed a delayed symptomatic pseudoaneurysm of the posterior tibial artery in the absence of tibia fracture. Superselective endovascular treatment with Ethylene Vinyl Alcohol Copolymer based liquid embolic system (Menox) was successfully performed, achieving exclusion of the pseudoaneurysm with preservation of the remaining vascularization of the lower limb.

Appendiceal mucocele is an uncommon entity that may arise due to benign or malignant processes. The radiologic exploration of this entity is necessary for diagnosis, and its imaging manifestations vary, with some findings being more common than others. More specifically, the radiological findings of a superinfected mucocele are rare, with few reports in the literature. Herein we present the case of a 68-year-old male patient with a superinfected appendiceal obstructive mucocele caused by a fecalith, which was diagnosed by abdominal CT evaluation.
