Myocardial perfusion imaging in a case of cardiac strangulation: A novel approach to detect pacemaker-induced ischemia.

Cardiac strangulation is a rare phenomenon in children following epicardial pacemaker implantation, caused by compression of the heart and great vessels by the epicardial pacemaker wires. We report a rare case of cardiac strangulation presenting after 8 years of epicardial pacemaker implantation. On routine follow-up, computed tomography angiography showed significant extrinsic compression of the mid-left anterior descending (LAD) artery by the epicardial pacing wire.

Beyond the Marrow: Unveiling Uncommon Sites of ALL Relapse with F-FDG PET/CT.

Extramedullary infiltration of acute lymphoblastic leukemia/lymphoma (ALL) to genital organs is extremely rare. Here, we present a case report of an asymptomatic 49-year-old female, known case of precursor B-cell ALL, who was incidentally detected with thickened and heterogeneously hyperechoic endometrium on sonography. Contrast magnetic resonance imaging detected large polypoidal enhancing lesions showing intense diffusion restriction occupying the endometrial cavity and similar lesions in the left adnexa, left ovary, and fallopian tube which were suspicious for leukemic infiltration because of the clinical history and atypical appearance of the lesions.

Trifecta of Tumors: Simultaneous Detection of Three Primary Malignancies by Different Radiotracers of Nuclear Medicine.

Malignancies are increasing worldwide with changing lifestyle, pollution, increasing life expectancy, and diagnostic advancements. However, multiple primary malignancies (MPMs) detected simultaneously are very rare. Here, we present a rare case of three primary malignancies (sigmoid colon, prostate, and thyroid) detected simultaneously in a 77-year-old male patient, who initially presented with bleeding per rectum and was then found to have a large pedunculated mass in the sigmoid colon on colonoscopy, which further turned out to be adenocarcinoma.
