F-Fluorocholine (F-FCH) PET/CT is widely used to study patients affected by prostate cancer. F-FCH PET/CT is suitable for the detection of pelvic and abdominal nodal and skeletal metastases. Indeed, F-FCH PET/CT sensitivity for other organs, such as the liver and the urinary tract, is lowered by the radiopharmaceutical urinary washout and intense liver uptake. Herein, we report the case of a patient affected by oligometastatic prostate cancer in good clinical condition treated with total androgen blockade. F-FCH PET/CT showed a diffuse and intense uptake in the shaft of the penis, which was an evidence of a rare penile metastasis.

Up-to-Date Imaging for Parathyroid Tumor Localization in MEN1 Patients with Primary Hyperparathyroidism: When and Which Ones (A Narrative Pictorial Review).

Patients diagnosed with multiple endocrine neoplasia type-1 (MEN1) often initially present with primary hyperparathyroidism (pHPT), and typically undergo surgical intervention. While laboratory tests are fundamental for diagnosis, imaging is crucial for localizing pathological parathyroids to aid in precise surgical planning. In this pictorial review, we will begin by comprehensively examining key imaging techniques and their established protocols, evaluating their effectiveness in detecting abnormal parathyroid glands.

Article Synopsis
- This study assessed the effectiveness of F-fluorocholine (FCH) PET/CT for locating hyperfunctioning parathyroid glands in patients with primary hyperparathyroidism (PHPT) before surgery.
- The research involved 80 patients who underwent FCH PET/CT, comparing the imaging results with histological findings and postoperative outcomes to evaluate the method's diagnostic performance.
- Results showed that FCH PET/CT had a sensitivity of 88% and a positive predictive value of 91%, indicating it is a valuable tool for pre-surgical localization of problematic parathyroid tissue in PHPT patients.*
A challenging diagnosis of prostate cancer seeding in the perineal needle-tract after transperineal biopsy: is PET-CT the imaging of choice?

Perineal seeding is an extremely rare complication after prostate biopsy. We found a perineal localization of prostatic adenocarcinoma 5 years after the transperineal biopsy in a patient with metastatic castration resistant prostate cancer. The tumor was identified by aF-Fluorocholin positron emission tomography-computed tomography (F-FCH PET-CT) performed after a sudden rise of PSA levels during androgen deprivation therapy and after a negative CT scan.

The utility of the [18]F fluorodeoxyglucose positron emission tomography-computed tomography ([18]F FDG PET-CT) marker for breast cancer is well established. Given its limitations in localizing FDG-negative malignant tumors, the expression of [18]F-fluorocholine ([18]-FCH) may potentially be helpful to improve the overall accuracy in evaluating breast cancer. This study determined the potential of [18]- FCH PET CT as a potential marker in assessing breast cancer phenotypes.

Parathyroid pathologies are suspected based on the biochemical alterations and clinical manifestations, and the predominant roles of imaging in primary hyperparathyroidism are localisation of tumour within parathyroid glands, surgical planning, and to look for any ectopic parathyroid tissue in the setting of recurrent disease. This article provides a comprehensive review of embryology and anatomical variations of parathyroid glands and their clinical relevance, surgical anatomy of parathyroid glands, differentiation between multiglandular parathyroid disease, solitary adenoma, atypical parathyroid tumour, and parathyroid carcinoma. The roles, advantages and limitations of ultrasound, four-dimensional computed tomography (4DCT), radiolabelled technetium-99 (Tc) sestamibi or dual tracer Tc pertechnetate and Tc-sestamibi with or without single photon emission computed tomography (SPECT) or SPECT/CT, dynamic enhanced magnetic resonance imaging (4DMRI), and fluoro-choline positron emission tomography (F-FCH PET) or [C] Methionine (C -MET) PET in the management of parathyroid lesions have been extensively discussed in this article.
