We report the clinical case of an adult patient referred to our hospital because of trismus due to a tumour in the right infratemporal and pterygomaxillary fossa. He referred hyporexia, weight loss and right trigeminal neuralgia. On physical examination, he had trismus and diplopia. On neuroimaging, the tumour invaded the central nervous system affecting the right temporal lobe and orbit, and the sellar region. Tumour biopsy revealed foamy histiocytes and isolated giant multinuclear cells immunoreactive to CD68 and negative to CD1a and S100...

AIM: The differentiation of osteomyelitis from bone tumors is of great importance in clinical decision-making; however, the features of both osteomyelitis and bone tumors are noncontributory. Tc-ubiquicidin scintigraphy is a new promising method with the ability to specifically localize the infection site by bacterial cell membrane binding. This study aimed to evaluate the ability of this radiopeptide for the differentiation of these two entities. PATIENTS AND METHODS: Thirty consecutive patients (mean age=20...

INTRODUCTION: Necrotizing otitis externa remains a severe and sometimes life-threatening disease in diabetic patient. Many therapeutic approaches have been described but what about the real benefit of hyperbaric oxygenotherapy in the management of this disease? METHODS: The authors reported a retrospective study about 42 patients treated for necrotizing external otitis over a period of 9 years (2006 to 2014). The patients were treated either by only antibiotherapy (23 cases) or with both antibiotherapy and hyperbaric oxygenotherapy (19 cases)...

Fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) has been recommended as a complementary tool for the staging of various malignancies, including malignant lymphoma. PET findings often shift patients to higher stages and may affect treatment outcomes. In this study, we retrospectively compared staging and treatment outcomes of newly diagnosed diffuse large B-cell lymphoma (DLBCL) assessed by PET (n = 153) or gallium-67 scintigraphy (Ga) (n = 95). In total, Ga upstaged two (2.1%) of 95 patients, whereas PET upstaged 13 (8...

Primary hyperparathyroidism is a disease that occurs more frequently than generally thought and is often overlooked. Classical symptoms are bone pain and osteoporosis, renal calculi and peptic ulcers. Many patients are asymptomatic or have unspecific complaints. It is easy to establish the biochemical diagnosis based on calcium and parathormone (PTH) levels and 24-h urine calcium excretion. The most sensitive localization procedures for parathyroid adenomas are sonography and Tc-99(m)-MIBI scintigraphy. The indication for surgery is undisputed in symptomatic patients; however, there is controversy concerning patients without classical symptoms...

INTRODUCTION: The most common cause of chronic hypercalcemia is primary hyperparathyroidism (PHPT). However, owing to the diverse presentation of hypercalcemia, the diagnosis often goes unnoticed culminating as a continuum of recurrence of symptoms. Nephrolithiasis, decreased bone mineral density and peptic ulcer disease are the main clinical sequelae. Among the causes of PHPT 80% are caused by parathyroid adenomas (PA). However, only rarely, these adenomas are found ectopically. PRESENTATION OF CASE: We present the case of a 66-year-old female with a history of recurrent renal stones and peptic ulcer disease...

Posttreatment imaging of primary bone tumours represents a diagnostic challenge for radiologists. Depending on the primary bone tumour common radiological procedures, such as radiography, computed tomography (CT), and magnetic resonance imaging (MRI), are employed. Radiography and CT are particularly useful in benign bone tumours and in matrix-forming bone tumours. MRI comes into consideration with malignant tumour recurrence and tumoral soft tissue infiltration. Bone scintigraphy is of superior importance if a primarily multifocal manifestation of bone tumour or metastasizing tumour disease is suspected...

Tc-99m-methylene diphosphonate (MDP) whole body scintigraphy is the method of choice for detection of metastatic bone diseases. It is primarily used to help diagnose various bone-related conditions such as primary or metastatic cancer of the bone, location of bone inflammation, and fractures that may not be visible on traditional X-ray images, as well as detection of bone damage due to infections and other conditions. In addition, bone scanning is often used for the follow-up or evaluation of response to treatment in some malignancies like prostate and breast cancers...

The appearance of a hot kidney on bone scintigraphy is rare and can be seen due to various factors. In our clinic, we observed hot kidney appearance in two patients to whom technetium-99m methylene diphosphonate (Tc-99m MDP) whole body scan has been performed: a young male adult at the age of 18 who was diagnosed with acute lymphocytic leukemia with a presumptive diagnosis of avascular necrosis, and a 9-year-old girl with cystitis for a pre-diagnosis of osteomyelitis. The first patient had a history of cyclosporine usage and the second patient was being treated with amikacin + vancomycin...

Super scan is a well-known finding described in skeletal scintigraphy characterized by uniform symmetrically increased radiopharmaceutical uptake by bones and consequently diminished renal parenchymal activity. Sy et al. hypothesized that the faint visualization of renal cortex in bone scintigraphy might be the result of increased uptake of radiopharmaceutical by pathologic bones and reduced phosphate excretion. The super scan on (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) has been observed in various conditions such as prostate cancer, lung cancer, renal adenocarcinoma, gastric cancer and primitive neuroectodermal tumor of the kidney...

OBJECTIVE: Seronegative spondyloarthritis (SpA) is characterized by chronic inflammation affecting the axial skeleton, entheses and occasionally peripheral joints. The involvement of the sacroiliac joints, sacroiliitis, is considered as a pathognomonic radiographic finding. Magnetic resonance imaging (MRI) is the method of choice for its early detection. Bone scintigraphy (BS) is characterized by high sensitivity in the diagnosis of bone and articular diseases. Limited value of BS in the diagnosis of sacroiliitis may be attributed to the use of planar imaging...

BACKGROUND: Radium-223-dichloride (Ra-223) is an alpha-emitting, bone seeking radionuclide therapy approved for patients with metastatic castration-resistant prostate cancer (mCRPC). In the fall of 2014, a global temporary shortage of Ra-223 occurred for 2 months due to production irregularities. The aim of this study was to assess whether prolonged interval between Ra-223 cycles to non-disease related causes had a negative impact on clinical outcome of therapy. MATERIALS AND METHODS: Retrospective single-center study of mCRPC patients who initiated Ra-223 therapy in the period from March 2014 to February 2015...

PURPOSE: The quality of conventional bone scintigraphy can be poor in patients with end-stage renal disease (ESRD). Fluorine-18-sodium fluoride (F-NaF) PET-computed tomography (CT) has rapid single-pass extraction, fast clearance from the soft tissues and a better target to background ratio. The aim of the present study is to preliminarily assess the superior tracer kinetics of F-NaF in ESRD patients. MATERIALS AND METHODS: A cohort comprising of 13 patients with ESRD (mean age 65...

Skeletal metastases are severe complications in the course of cancer, and they indicate a worse prognosis. The use of modern imaging techniques allows rapid diagnosis of bone metastases. Properly selected diagnostic imaging (scintigraphy, positron emission tomography, whole body MRI) allows us to evaluate the number of metastatic foci in the skeletal system. Complementary imaging examinations (X-ray, computed tomography, magnetic resonance imaging) determine the extent of metastasis and its character: osteolytic, osteoblast, mixed)...

BACKGROUND Synchronous bilateral breast cancer is rare. A case is presented where whole breast irradiation (WBI) was planned after breast conserving surgery in a patient with synchronous bilateral breast cancer. A comparison was made between the feasibility of helical tomotherapy and direct tomotherapy. CASE REPORT A 60-year-old woman was found to have bilateral breast nodules on routine mammographic screening, resulting in bilateral lumpectomy and sentinel lymph node biopsy. Histopathology showed a 6 mm diameter invasive ductal carcinoma in the right breast (Grade 1, hormone receptor positive, HER2 negative) and an 8mm diameter tubular carcinoma in the left breast (Grade 1, hormone receptor positive, HER2 negative)...
