Parathyroid carcinoma is a very rare malignant tumor of the parathyroid gland. Clinically, this cancer is characterized by the presence of severe primary hyperparathyroidism. Diagnosis is based on histological examination but is not always easy. Surgery is the treatment of choice. We report the case of a 59-year old woman with a personal history of arterial hypertension and of recurrent renal lithiasis, presenting with diffuse bone pain associated with asthenia. Neck examination showed hard basi-cervical swelling with nonpalpable lower edge...

We are witnessing an era of increased clinical interest in metastatic castration-resistant prostate cancer, both in terms of treatment and also in terms of imaging options. This surge in interest is attributed to the recent developments in treatments for metastatic prostate cancer that are able to confer a significant survival advantage. We are therefore anticipating an increase in the number of patients that we will need to treat at this disease stage. Imaging is undoubtedly crucial in monitoring disease response to treatment and progression...

Osteosarcomas are especially rare in the mandible and maxilla, representing 1.6% of all bony malignant tumours. In this article, we described a case of osteosarcoma of the mandible. Computed tomography (CT) image showed a well-circumscribed homogeneous mass, with nonhomogeneous contrast enhancement. T1-weighted magnetic resonance imaging (MR) image showed intermediate signal intensity on, and after administration the lesion showed signal intensity lower than muscle. T2-weighted MR image showed heterogeneous high signal intensity...

A Tc-MDP bone scintigraphy was performed in an 88-year-old man with a history of right external oblique muscle leiomyosarcoma, which was resected 8 months ago. The static images showed abnormal tracer uptake in the region of resection bed. SPECT/CT images demonstrated that the increased activity was from a partially calcified soft tissue mass in external oblique muscle. Subsequent pathological examination confirmed recurrent tumor.

A 64-year-old man with lung cancer with a history of revascularization of the occluded right femoral artery underwent bone scintigraphy, which showed intense uptake in the distal side of the right leg. The additional SPECT/CT clarified that the uptake was predominantly increased in the epiphyses of the right ankle and foot with possible osteopenia. One month later, follow-up SPECT/CT showed the manifestation of periosteal resorption in the hypermetabolic sites with slight decrease in bone metabolism. Radiological correlation between bone metabolism and subsequent bone resorption in addition to clinical symptoms in this patient suggested the diagnosis of reflex sympathetic dystrophy...

We present 3 cases of patients with castration-resistant prostate cancer and bone metastases treated with Ra, belonging to our prospective and multicenter ChoPET-Rad study. All patients underwent clinical, hematological, and biochemical monitoring between each Ra administration. Initial and follow-up F-fluorocholine PET/CT and Tc-biphosphonate bone scintigraphy were performed previously and after the third Ra administration. Both techniques correctly established the response to treatment, in agreement to the biochemical response, although differences in the disease expression (concordant and discordant patterns) were found because of the different radiotracer biodistribution and molecular information derived from them...

We present images of a 13-year-old boy with Gorham-Stout disease affecting the mandible. Initial bone scintigraphy showed poor visualization of Tc-methylene diphosphonate (Tc-MDP) uptake in the mandible body. However, abnormally increased Tc-MDP uptake was noted in the bilateral mandibular rami. In the follow-up examination a year later, bone scintigraphy indicated that the disease had progressed to the bilateral mandibular rami with no uptake. In addition, massive osteolysis of the mandible was noted that had progressed since the initial computed tomography...

Prostate cancer is the second most common cancer in men worldwide, with a wide spectrum of biologic behavior ranging from indolent low-risk disease to highly aggressive castration-resistant prostate cancer. Conventional imaging with computed tomography, magnetic resonance imaging, and bone scintigraphy is limited for the detection of nodal disease and distant bone metastases. In addition, advances in the available therapeutic options, both localized and systemic, drive the requirement for precise diagnostic and prognostic tools to refine the individual therapeutic approach at various times in the management of patients with prostate cancer...

Pediatric skeletal scintigraphy is a noninvasive imaging modality which aids in functional as well as anatomic evaluation of bone. Bone scintigraphy plays a major role in diagnosis and evaluation of various benign, primary malignant and metastatic pediatric bone pathologies. The advantage of bone scan is that it becomes positive well before the bone pathology is evident on radiographs and specifically the entire skeleton can be imaged in a single examination. Pediatric bone scintigraphy evaluation can be challenging to the general radiologist not routinely exposed to the study, as the growing skeleton is quite different from a mature skeleton especially at or near the growth plates...

PURPOSE: Bone scintigraphy is the standard of reference in bone metastases in prostate cancer patients. However, new radiotracers employed in prostate-specific membrane antigen (PSMA)-ligands has led to the growing importance of PET/CT as diagnostic tool. The aim of our study was to investigate the difference between bone scan and PSMA-PET/CT for the detection of bone metastases in prostate cancer. METHODS: Thirty patients with bone metastases originating from prostate cancer were examined by (99m)Tc-MDP bone scan and (68)Ga-PSMA-PET/CT within an average of 21 days...

Nuclear medicine imaging is widely used in pain medicine. Low back pain is commonly encountered by physicians, with its prevalence from 49% to 70%. Computed tomography (CT) or magnetic resonance imaging (MRI) are usually used to evaluate the cause of low back pain, however, these findings from these scans could also be observed in asymptomatic patients. Bone scintigraphy has an additional value in patients with low back pain. Complex regional pain syndrome (CRPS) is defined as a painful disorder of the extremities, which is characterized by sensory, autonomic, vasomotor, and trophic disturbances...

BACKGROUND: Fibrous dysplasia (FD) is a rare benign bone disorder in which the normal bone is replaced by immature fibro-osseous tissue. However, some case reports have reported that FD showed significantly increased (99m)Tc-methylene diphosphonate ((99m)Tc-MDP) uptake on whole-body bone scintigraphy (WBS), which may mimic bone metastasis or skeletal involvement of the patients with known cancer. Thus, the purpose of present study is to observe the reliable characteristics and usefulness of single photon emission computed tomography/computed tomography (SPECT/CT) for the diagnosis of FD...
