Background: We aimed to present unusual cranial FDG PET/CT findings of a 56-year-old female with multiple myeloma (MM).
Case Report: Plain CT images revealed a lytic lesion in the right parietal bone, filled with an oval-shaped, large, extra-axial, extradural, intracranial mass which measured 75×75×40 mm and had smooth borders. The right parietal lobe was compressed by the mass. The maximum standardized uptake value (SUV) of the mass lesion was 8.94 on FDG PET/CT images. Multiple lytic lesions with an increased uptake were also detected in other calvarial bones, in several vertebras and in the proximal left femur. After seven months, a control FDG PET/CT following radiotherapy and chemotherapy revealed almost complete regression of the right parietal extra-axial mass lesion. The number, size and metabolism of lytic lesions in other bones also decreased.
Conclusions: FDG PET/CT was useful for an initial evaluation of MM lesions and was effective in monitoring the response of these lesions to therapy.

Breast metastasis from rectal carcinoma is very rare. We report a case of imaging findings of breast metastasis in a 31-year-old woman who underwent laparoscopic radical tumor resection 8 months ago. 68Ga-FAPI-04 PET/CT and 18F-FDG PET/CT showed 4 small breast nodules with intense 68Ga-FAPI uptake (SUVmax, 9.

Fibroblast activation protein (FAPI) has been recently incorporated as a molecular imaging radiotracer for the evaluation of epithelial neoplasms that support or complement the role of [F]Fluorodeoxyglucose ([F]FDG) in many cancer subtypes since its development. Both radiotracers have been shown to have diagnostic, prognostic, and predictive value for several neoplasms. Herein, we present a 73-year-old male patient with a complex medical and oncological history who was recently diagnosed with hepatocellular carcinoma (HCC).

Background: The study aimed to overview radiopharmaceuticals used for the nuclear medicine (NM) imaging of prostate cancer (Pca) since the first mentions in the literature up to recent reports, with the special focus on positron emission tomography-computed tomography (PET-CT) radiotracers.
Materials And Methods: We found over 3500 articles discussing the role of PET-CT in Pca patients' management published within 1990-2023. We summarized the past and present interests of the Authors when the Pca diagnostic imaging and the use of radiotracers in Pca diagnosis are considered.
Pneumoconiosis, caused by inhaling mineral dust, remains a significant occupational disease, despite a declining incidence. Coal workers' pneumoconiosis (CWP), a common subtype, varies in presentation from simple to complicated forms. Differential diagnosis is crucial, especially when CWP manifests as lung masses mimicking malignancy.

Positron emission tomography/computed tomography (PET/CT) using prostate-specific membrane antigen (PSMA)-radioligands is currently suggested by several clinical guidelines for the assessment of prostate cancer (PCa) in various clinical settings. However, PSMA will also be overexpressed in different cancers, which should be considered on the PSMA PET/CT reading in patients with concomitant neoplastic diseases. We report a case of 82-year-old male presented with prostate and history of oesophageal cancer and B-cell chronic lymphocytic leukemia (B-CLL).
