AI Article Synopsis
- - A 61-year-old man experienced urinary and defecation issues for 4 months, leading to an abdominal contrast-enhanced CT that showed large rectal masses suspected to be cancerous and affecting nearby organs.
- - An 18 F-FDG PET/CT scan was conducted for staging, revealing intense activity in masses involving the rectum, bladder, prostate, left ureter, and abdominal wall in the pelvic area.
- - Further histopathological analysis identified the masses as malakoplakia, characterized by specific cells (von Hansemann cells) and unique structures known as Michaelis-Gutmann bodies.
Article Abstract
Abdominal contrast-enhanced CT was performed in a 61-year-old man with difficulties of urination and defecation for 4 months, which revealed huge rectal masses involving multiple adjacent organs, suspected as malignant lesions. 18 F-FDG PET/CT was subsequently performed for staging. The images showed intense FDG uptake and slightly hyperdense masses involving rectum, bladder, prostate, left ureter, and the anterior abdominal wall at the level of the pelvic cavity. Histopathological examination confirmed the masses were due to malakoplakia, which displayed as abundant von Hansemann cells aggregated and infiltrated in lesions, with distinctive cytoplasmic inclusions termed Michaelis-Gutmann bodies.

Ductal carcinoma (DCIS), a noninvasive breast cancer, rarely metastasises to distant locations. When the initial lesion is stable, bone marrow metastasis (BMM) and bone marrow necrosis (BMN) are even less common. Here, we report the case of a 47-year-old female patient who underwent localized surgery and radiotherapy for right-sided DCIS.

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.

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).

Purpose: The study aimed to compare the diagnostic accuracy of Ga-DOTA-FAPI-04 (Ga-FAPI) and F-FDG PET/CT for peritoneal carcinomatosis (PC) in patients with various types of cancer.
Methods: The study enrolled 113 patients with suspected peritoneal malignancy, each of whom underwent Ga-FAPI and F-FDG PET/CT scans. Lesions in all patients were confirmed through pathology or radiological follow-up.
