We present a case of a tenosynovial giant cell tumor (TGCT) incidentally discovered at the shoulder on PET/CT, in a patient with history of thyroid cancer. Many documented cases of TGCT have been incidentally imaged by PET/CT and have been found to have varying levels of metabolic activity, however the shoulder location is unusual. This type of musculoskeletal lesion often has MRI characteristics, such as gradient echo blooming, which can render a confident diagnosis without need for biopsy.

Background: Long-axial field-of-view (LAFOV) Positron Emission Tomography (PET) scanners provide high sensitivity, but throughput is limited because of time-consuming patient positioning. To enhance throughput, a novel Walk-Through PET (WT-PET) scanner has been developed, allowing patients to stand upright, supported by an adjustable headrest and hand supports. This study evaluates the degree of motion in the WT-PET system and compares it with the standard PET-CT.

Hibernomas are rare brown fat tumors that garnered attention in the literature with the increasing use of [F] Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography ([F] FDG PET/CT) for the staging workup and follow-up of solid malignancies. Despite being benign tumors, they exhibit high metabolic activity due to their thermogenic nature, leading to significant radiotracer uptake on functional imaging. This can pose a challenge in differentiating them from the malignant lesions, especially the fat-containing malignancies such as liposarcoma.

Background: Primary pericardial mesothelioma (PMPM) is a rare, aggressive, and lethal form of cancer. Due to its rarity, low incidence and poor prognosis, PMPM has no accepted standard-of-care treatment options with management and outcomes often extrapolated from diffuse pleural mesothelioma. Disease-specific studies are needed to better define PMPM.

Article Synopsis
- A new derivative of minigastrin, DOTA-CCK-66, shows promising results in imaging and therapy for medullary thyroid carcinoma (MTC) when labeled with either Gallium (Ga) or Actinium (Ac).
- In a study using tumor-bearing mice, treatment with either Lu- or Ac-labeled DOTA-CCK-66 significantly reduced tumor growth and increased survival times compared to a control group treated with Ga-labeled DOTA-CCK-66.
- The Ac-labeled treatment resulted in the highest mean survival rate, indicating its strong therapeutic potential for MTC in future patient management.

Background: Biliary tract cancers (BTCs) are a diverse group of malignancies with varied genetic backgrounds. The prevalence of intrahepatic cholangiocarcinoma (iCC) is increasing, particularly in Western countries. Despite advancements in treatments, the prognosis for BTC remains poor.
