Pheochromocytoma is a rare tumor located in the medulla of the adrenal gland that is characterized by high catecholamine synthesis. Surgery is the treatment of choice and is usually curative if appropriately diagnosed and excised. Imaging methods, both morphological and functional, are of great importance in presurgical evaluation.We report the case of a female patient with multiple endocrine neoplasia...
We report the clinical value of FDG PET/CT imaging in a 57-year-old woman who was diagnosed with uterine leimyosarcoma 6 years ago. In a staging procedure, whole body FDG PET/CT discloses the presence of both local recurrence and remote metastases at widespread musculocutaneous sites, liver and femur. With its advantage of scanning the whole body in a single procedure, we propose the use of PET/CT...
We present a case of a 78-year-old female with effort angina. A myocardial perfusion SPECT (MPS) showed increased tracer uptake in two synchronic tumor lesions, a thymoma and a breast cancer. This case highlights the contribution of SPECT-CT in the characterization of these findings and its essential role in rapid decision-making. The patient underwent surgery of both lesions that had gone undetected...
Multicentric reticulohistiocytosis is a rare systemic disease of unknown etiology. It is characterized by erosive arthritis and skin lesions. Diagnosis and treatment should be performed early to avoid sequelaes.We report the case of a 67-year-old man diagnosed with multicentric reticulohistiocytosis and left hip arthroplasty. The patient consulted for local pain in his left leg. Final diagnosis was...
Intravascular lymphoma is a rare subtype of extranodal Non-Hodgkin's lymphoma. Its prognosis is poor in a high percentage of cases due to its insidious appearance and low clinical suspicion. Its diagnosis is usually only reached after an autopsy. It may affect different organs as a whole or only one organ. It is extremely rare that the lung is the only damaged organ. Its diagnosis depends on the clinician's...
There is no general consensus on the optimal criteria for the application of bone scintigraphy in screening of bone metastasis in patients with prostate cancer. Our study was conducted to assess the value of bone scan for pre-treatment staging of asymptomatic treatment-naïve patients with prostate cancer.A total of 203 consecutive asymptomatic and treatment-naïve patients with prostate cancer (age:...
Since Pall-Gelman stopped manufacturing ITLC-SG, it has become necessary to validate alternative stationary phases.To validate different stationary phases versus ITLC-SG Pall-Gelman in the determination of the radiochemical purity (RCP) of 111 In-pentetreotide ( 111 In-Octreoscan) by planar chromatography.We conducted a case–control study, which included 66 111 In-pentetreotide...
In the context of the limitations of structural imaging, brain perfusion and metabolism using SPECT and PET have provided relevant information for the study of cognitive decline. The introduction of the radiotracers for cerebral amyloid imaging has changed the diagnostic strategy regarding Alzheimer's disease, which is currently considered to be a “continuum.” According to this new paradigm, the increasing...
Several case reports describing the coexistence of sarcoidosis and malignancy have been published. Therefore, sarcoidosis should always be considered as a differential diagnosis when a cancer patient develops lymphadenopathy. Positron-emission tomography (PET) 2-[18F]-fluoro-2-deoxy-d-glucose (FDG) combined with computed tomography (CT) is widely used for cancer staging and surveillance because it...
The body mass index (BMI) is used to assess nutritional status. The result in athletes may be overestimated due to increase in muscle mass.To assess the usefulness of fat mass index (FMI) and lean mass index (LMI) determination as indicators of nutritional status and to compare the results with BMI.We studied 28 amateur rugby players, male. After being subjected to whole body densitometry by dual...
