A 75-year-old patient was diagnosed with a Gleason 9 prostate carcinoma. His PSA level was 50.4 ng/ml. Routine bone scintigraphy was negative for metastasis (a). Due to the high tumour grading and relatively high PSA level, (68)Ga-PSMA PET-CT was ordered to rule out distant metastases. This scan showed numerous skeletal lesions with high tracer accumulation as sign of diffuse osseous metastases (b). On low-dose CT there were no signs of sclerosis (c). (68)Ga-PSMA PET-CT also showed high uptake in the prostate and in para-iliac and para-aortal lymph nodes, without lymph node enlargement...

Systemic sclerosis (SSc) is a rheumatic autoimmune disease of unknown origin causing fibrosis of the skin and the internal organs. The limited cutaneous variant is the most common subtype of SSc, and it is predominantly characterized by skin and soft-tissues involvement. A 72-year-old woman, who had been diagnosed with the limited cutaneous form of SSc 16 years before, underwent fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) examination due to unexplained weight loss and recent onset of fatigue and joint pain...

Systemic sclerosis (SSc) is a rare autoimmune disease, which may affect multiple organ systems. Fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) can demonstrate the degree and anatomical extent of involvement in the entire body and coexisting malignancies in connective tissue diseases. We present a case of SSc with an increased 18F-FDG uptake in the cutaneous and subcutaneous tissues even higher than the neighboring skeletal muscles ("flip-flop phenomenon," that is, an increased 18F-FDG uptake in the skin but a decreased 18F-FDG uptake in the skeletal muscles)...

BACKGROUND: Difficulties in ambulation are one of the main problems reported by patients with multiple sclerosis. A previous study by our research group showed increased recruitment of muscle groups during walking, but the influence of skeletal muscle properties, such as muscle fiber activity, has not been fully elucidated. The purpose of this investigation was to use the novel method of calculating glucose uptake heterogeneity in the leg muscles of patients with multiple sclerosis and compare these results to healthy controls...

Modern imaging procedures play an import role in diagnostic and therapy-control in rheumatic diseases. Reasons are the continuous development, the evaluation and the implementation in local / international guidelines and classification criteria. According to new therapeutic goals and the aim of clinical and radiological remission the early diagnosis and sufficient therapy-control is unalterable. The ultrasound is today an inherent tool in the early diagnosis of joint- and vascular diseases and is used comprehensively in rheumatic diseases...

Positron emission tomography (PET) of the brain is an important problem-solving tool in pediatric neuroimaging, neurology, and neurosurgery. Fluorine 18 fluorodeoxyglucose (FDG) PET or dual-modality PET and computed tomographic (CT) imaging (PET/CT), with magnetic resonance (MR) imaging correlation, can be used to evaluate childhood epilepsy and pediatric brain tumors, areas in which PET adds value in patient management. FDG PET has been widely used in pediatric temporal lobe epilepsy, most commonly manifesting as mesial temporal sclerosis, which demonstrates hypometabolism at interictal PET and hypermetabolism during seizures...

Scleromyxedema is a generalized skin disease mostly associated with monoclonal gammopathy. In its chronic course, it can lead to systemic disorders related to mucin deposits in organs. We describe here specific lymph node involvement, hitherto not reported in scleromyxedema. A 68-year-old man with a 1-year history of micropapular eruption and skin sclerosis involving the neck, trunk, hands, and face was diagnosed with scleromyxedema associated with IgG kappa monoclonal gammopathy. Enlarged mediastinal lymph nodes found on thoracic X-ray and computed tomography scan were hypermetabolic on positron emission tomography...

Hodgkin lymphoma (HL) is a curable malignancy which shows a bimodal curve in incidence in economically developed countries; there is a putative association with Epstein-Barr virus. The WHO 2008 classification schema recognises two histological types of HL: the nodular lymphocyte predominant and the "classic" HL. The latter encompasses four entities: nodular sclerosis, mixed cellularity, lymphocyte depletion, and lymphocyte-rich. Most patients with HL present with asymptomatic superficial lymphadenopathy. The commonest sites of disease are the cervical, supraclavicular and mediastinal lymph nodes, while sub-diaphragmatic presentations and bone marrow and hepatic involvement are less common...

Malignant pleural mesothelioma (MPM) is a relatively rare but aggressive pleural tumor. Systemic sclerosis (SSc) is associated with the development of lung cancer and other malignancies. We describe a 58-year-old never-smoker female, previously diagnosed with limited cutaneous SSc, who presented with chest pain on the left side, dyspnea and circumferential nodular left pleural thickening. Fluorodeoxyglucose positron-emission tomography-computed tomography showed intense uptake in the thickened left pleura, mediastinal lymph nodes and left femur...

Autoimmune pancreatitis is the pancreatic manifestation of a novel clinicopathological disorder called systemic IgG4-related sclerosing disease. Beside the pancreas, this entity affects other sites (salivary glands, orbit, lung, thyroid, gallbladder, biliary tree system, kidney, abdominal aorta, retroperitoneum, prostate, and lymph node) by infiltration with IgG4-positive plasma cells. Several case reports and small case series have demonstrated the utility of integrated positron emission tomography/computed tomography (PET/CT) in monitoring therapy and documenting relapse and flare-up of autoimmune pancreatitis...

Systemic sclerosis (SSc) is a chronic disease of unknown etiology which affects the vascular system and connective tissue. A wide series of studies showed an increased prevalence of cancer in patients with SSc than the normal population. Prostacyclin (PGI2) is an endogenously produced element that is basically synthesized by arachiodonic acid through prostacyclin synthesis in vascular system endothelial cells. Iloprost is a stable analogue of PGI2 which is used in the treatment of pulmonary arterial hypertension (PAH)...

The endocannabinoid system modulates neuronal excitability, protects neurons against hyperexcitability and is involved in epileptogenesis in animal models of mesial temporal lobe epilepsy with hippocampal sclerosis. We performed in vivo positron emission tomography imaging of the type 1 cannabinoid receptor in patients with mesial temporal lobe epilepsy with hippocampal sclerosis. Twelve patients with refractory mesial temporal lobe epilepsy due to hippocampal sclerosis received a [(18)F]MK-9470 scan to assess type 1 cannabinoid receptor availability in vivo...

Numb chin syndrome (NCS) is a rare but important clinical symptom and sign. It describes a condition presenting as anaesthesia or paraesthesia over the chin, which is usually unilateral. The condition manifests spontaneously with no history of trauma, infection or obvious odontogenic cause. NCS is a clinically important finding as it may be the primary manifestation of Multiple Sclerosis (MS) or sign of systemic malignancy. We present a case of a 58-year-old gentleman who was referred to a regional oral and maxillofacial unit with a three-month history of sudden onset unilateral numbness of the chin...

Malignant lymphoma (ML) is frequently associated with several forms of collagen diseases such as Sjören syndrome, systemic lupus erythematodes, and rheumatoid arthritis. However, the occurrence of ML in systemic sclerosis (SSc) patients has rarely been reported. Here we report an SSc patient who developed mediastinal (thymic) large B-cell lymphoma (MLBCL). A 31-year-old woman was diagnosed as having SSc in August 2007. The patient was treated with low-dose prednisolone (10 mg/day) without any effect. One year after the diagnosis, chest computed tomography-scan demonstrated thymic tumor in the anterior mediastinum...
