BACKGROUND Stress fractures are the injuries of soft tissues and bones caused by intensive and repeated stress on a bone. Repeated submaximal stress disturbs the balance between the processes of bone production and resorption that results in fracture. CASE REPORT We presented a case of a patient with stress fracture of metatarsal bone. The patient was diagnosed and treated as having reactive ...

AIM The accuracy of bone scintigraphy in diagnosing symptomatic accessory navicular bones has not been well studied. We conducted a retrospective study to explore the results and use of scintigraphy in symptomatic and asymptomatic accessory navicular bones. MATERIALS AND METHODS Thirteen patients with a total of 13 symptomatic and 10 asymptomatic accessory navicular bones were included in the...

Multiple benign osteolytic lesions are very hard to differentiate from disseminated bone metastasis. Whole-body bone scintigraphy (WBBS) with technetium-99m methylene diphosphonate (Tc-99m MDP) demonstrates multiple lesions with increased uptake in any bone involved. Even combined with medical history and multiple imaging results, such as MRI and CT, the clinical diagnosis of metastasis lesion ...

Meningeal extramedullary hematopoiesis (EMH) is a rare finding in idiopathic myelofibrosis. Intracranial EMH is typically asymptomatic and sites are usually found by chance. Diagnosis of EMH is difficult, based on clinical circumstances and the use of different diagnostic imaging modalities, such as CT, MRI or radionuclide imaging. We present a case with intracranial medullary hematopoiesis due...

UNLABELLED Neurofibromatosis type 1 or von Recklinghausen's disease is one of the most common autosomal dominant genetic disorders. Between 29% and 77% of patients may suffer from a wide range of skeletal abnormalities and, thus, patients with neurofibromatosis frequently undergo skeletal scintigraphy, at which time the common peripheral nerve soft-tissue tumors that occur in this syndrome (neu...

A number of people suffered rhabdomyolysis caused by eating crayfish in China and the final diagnosis was a rare disease called Haff disease. In this study, we present a 26 years old man with a history of severe muscular soreness for whole body after eating crayfish and this status lasted for about 3 months. Blood analysis showed significant increase in serum creatine kinase and lactate dehydro...

Extraction of impacted third molars is a well-established and documented procedure. Guided tissue regeneration can be used to aid in wound healing and increase osseous tissue formation. To assess the regenerative treatment outcome, several variables are routinely used; these include primarily histology and direct measurement of bone. Other proxy measurements, such as radiographic analysis, clin...

AIM The aim of this study was to evaluate the value of bone scintigraphy for the assessment of graft viability following vascularized bone grafts in patients with mandibular reconstruction. METHODS We investigated 16 patients with vascularized grafts from the fibula (13 patients) and iliac crest (3 patients) in the last 8 years. For the follow up of all these patients, Tc-99m MDP bone scintig...

Metastatic pulmonary calcification is a complication of patients with renal failure [1], but is rarely seen after successful renal transplantation. A 51-year-old Japanese male demonstrated progression of diffuse pulmonary ground-glass attenuations over time. He had been treated with oral corticosteroids and immunosuppressants since undergoing left renal transplantation from his mother at 26 yea...
