18F-Fluorine-18-l-dihydroxyphenylalanine (18F-DOPA) positive isolated peritoneal carcinomatosis from a MENII-related medullary thyroid carcinoma. About an atypical metastatic site and utility of 18F-FDOPA

چکیده
A patient, operated for a medullary thyroid carcinoma (MTC) with a positive RET mutation, showed several peritoneal nodes on a computed tomography (CT), with increased Thyrocalcitonine. A (18)F-Fluorine-18-l-dihydroxyphenylalanine (18-F-FDOPA) positron emission tomography (PET/CT) showed isolated tracer uptake on the nodes. A biopsy confirmed that it was from the MTC, with the same RET mutation as in blood.

BACKGROUND 6-18F-fluoro-L-3,4-dihydroxyphenylalanine (18F-FDOPA) PET is a useful tool in the clinical management of pheochromocytoma (PHEO) and medullary thyroid carcinoma (MTC). 18F-FDOPA is a large neutral amino acid biochemically resembling endogenous L-DOPA and taken up by the L-type amino acid transporters (LAT1 and LAT2). This study was conducted to examine the expression of the LAT syste...

Objective(s): In clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (DTC) patients with high serum thyroglobulin (Tg) and negative 131I whole-body scan (WBS) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. The purpose of this study was to evaluate the value of 18F-FDG PET/CT scan in DTC patients with high seru...

Introduction: Clinical examination and even anatomical imaging may fail to identify primary site of malignancy in patients presenting with cervical nodal metastasis. 18F-Fluorodeoxyglucose Positron Emission Computed Tomography (18F-FDG PET-CT) is known to overcome the limitations of anatomic imaging. Methods: Sixty-three (63) patient...

BACKGROUND An unknown location hampers removal of pancreatic tumours. We studied the effects of enzyme inhibitors on the uptake of 6-[18F]fluoro-l-3,4-dihydroxyphenylalanine ([18F]FDOPA) in the pancreas, aiming at improved imaging of pancreatic adenocarcinoma. METHODS Mice bearing orthotopic BxPC3 pancreatic adenocarcinoma were injected with 2-deoxy-2-[18F]fluoro-d-glucose ([18F]FDG) and scan...

In a recent contribution of Scott et al., the substrate scope of Cu-mediated nucleophilic radiofluorination with [18F]KF for the preparation of 18F-labeled arenes was extended to aryl- and vinylstannanes. Based on these findings, the potential of this reaction for the production of clinically relevant positron emission tomography (PET) tracers was investigated. To this end, Cu-mediated radioflu...
