Mycotic pseudoaneurysm (or infected pseudoaneurysm) is an infectious arteritis, leading to the destruction of the arterial wall with the formation of a blind, saccular outpouching contiguous with the arterial lumen. Delayed management or non-management of mycotic pseudoaneurysms is associated with high morbidity and mortality due to complications such as arterial rupture, hemorrhage, and fulminant sepsis. Earlier diagnosis of mycotic pseudoaneurysm is essential for time management. Multidetector computed tomography (MDCT) is a widely used imaging modality for detecting the mycotic pseudoaneurysm, its characterization, and vascular mapping. MDCT findings of mycotic pseudoaneurysm are blind, saccular outpouching of an artery with irregular arterial wall, perivascular soft-tissue mass, or edema. Uncommon results of MDCT include arterial lumen thrombosis, arterial wall calcification, and perivascular gas. Management of mycotic pseudoaneurysm includes endovascular stenting with graft repair, endovascular embolization, open surgery, medical therapy (intravenous antibiotics), or a combination of these. We report three cases of mycotic pseudoaneurysm affecting aortic isthmus, a segmental branch of the pulmonary artery, and the internal mammary artery. All cases posed a diagnostic challenge, which only on subsequent imaging revealed to be a mycotic pseudoaneurysm.

Solid pseudo-papillary epithelial neoplasm (SPEN), also known Hamoudi tumors or Franz tumors, are rare pancreatic neoplasm which are almost always seen in young women predominately of non-Caucasian descent with only a small minority of cases diagnosed in men [1]. The rst published description of an SPN was by Frantz in 1959[2].It is a rare tumor comprising of less than 3 percent of all pancreatic tumor. It is seen most often in the region of tail of pancreas. This tumor is mostly asymptomatic and usually detected when it reaches large size. These are tumors with low malignant potential and rarely vascular invasion and metastatic disease can be seen in aggressive cases. Here we report two cases, one each of benign SPEN and malignant SPEN with contrasting imaging ndings and polar outcomes.

Cysticercosis cellulosae is a systemic parasitic infection caused by the larval stage of pork tapeworm, taenia solium which involve humans as either a denitive or secondary host. It is a common disease in developing countries. The cases presenting as an isolated muscle mass is an extremely rare entity and demands documentation. Herein, we present a case of healthy pediatric patient who presented with unilateral cheek swelling which on ultrasound suggested a benign cystic lesion. The diagnosis was conrmed on ne needle aspiration cytology (FNAC).
