Extraosseous accumulation of technetium-99m-methyl diphosphonate (99mTc-MDP) on bone scan is not common. This phenomenon is often attributed to abnormality of calcium metabolism and has been reported in a variety of conditions including metabolic diseases and malignancies. A five years old boy is presented here, who was admitted to the pediatric emergency suffering from fatigue, respiratory sym...

Calciphylaxis is a rare devastating medical condition commonly associated with end-stage renal disease and characterized by extensive microvascular calcifications. We describe a case of calciphylaxis presenting on Tc-99m MDP bone scan imaging with asymmetric radiotracer uptake within the lower extremities corresponding to extensive soft tissue calcifications on Computed tomography. Familiarity ...

Markedly elevated111 In labeled leukocyte activity suggestive of acute osteomyelitis was observed in a region of a composite mandibular allograft that was photon deficient on 99mTc MDP bone scintigraphy. This finding was later confirmed by surgical pathology. The patient was treated with intravenous antibiotics and returned two months later with persistent bone infection. The foHow-up thr...

Osteoid osteoma (OO) is a relatively common skeletal neoplasm, frequently involves long bones. OO of rib is extremely rare, including 0.23-2% of OO cases. Most of them arose in posterior arc, frequently in its head or neck and might lead to painful scoliosis. Involvement of anterior aspect of a rib is extremely rare. Skeletal scintigraphy is highly sensitive for detection of OO. “Doubl...

Neuroblastoma is the third most common malignancy of childhood. Nowadays, MIBG has become a central procedure for staging and defining extent and location of neuroblastoma tumors. The recommendations of the International Neuroblastoma Staging System (INSS) indicate that MIBG scintigraphy must be performed in patients with neuroblastoma at the time of initial staging and as a followup tool durin...

Despite the long history of worldwide use of bacillus Calmette-Guerin (BCG) vaccine, a wide spectrum of adverse reactions has been observed in a small proportion of immunized infants. The most severe complication is disseminated BCGitis, often fatal but extremely rare and considered to be a result of host immunodeficiency. At present, polymerase chain reaction test, CT scan, ultrasound, X-rays ...

A 57-year-old woman with a newly diagnosed lung cancer was referred for a bone survey as a part of cancer workup. An interesting finding on Tc-99m MDP bone scan was accumulation of radioactivity in the bowel, on account of self urine drinking before the imaging. Many people believe that drinking their own urine has a myriad of health benefits, nevertheless, none of which have been scientificall...

We report a 41 years old man with rapidly growing and tender lump on the anteromedial surface of tibia. The patient had the history of gastrectomy and gastrojejunostomy due to gastric carcinoma. On admission, the Simple X-ray of lower extremity disclosed a slight thinning of the anterior cortex of tibia without cortical destruction. The whole-body bone scan with (99m)TC MDP revealed activity of...

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...
