Hypercalcemia in accelerated phase of chronic myelogenous leukemia (CML) is very rare. Its pathogenesis is considered humoral hypercalcemia of malignancies mediated by parathyroid hormone-related protein (PTHrP). In severe hypercalcemia, calcifications in kidneys, skin, vessels, heart, and stomach may occur. Our two cases were admitted because of severe hypercalcemia in accelerated phase of CML. On Tc-99m methylene diphosphonate (MDP) bone scintigraphies, a marked tracer accumulation was seen in the lung, heart, stomach and kidney. We report increased tracer accumulation of multiple organs on Tc-99m MDP bone scintigraphy in two rare hypercalcemic patients with CML.

2.Nuclear Medicine Imaging Diagnosis in Infectious Bone Diseases.
Nuclear Medicine and Molecular Imaging 2006;40(4):193-199
Infectious and inflammatory bone diseases include a wide range of disease process, depending on the patient's age, location of infection, various causative organisms, duration from symtom onset, accompanied fracture or prior surgery, prosthesis insertion, and underlying systemic disease such as diabetes, etc. Bone infection may induce massive destruction of bones and joints, results in functional reduction and disability. The key to successful management is early diagnosis and proper treatment. Various radionuclide imaging methods including three phase bone scan, Ga-67 scan, WBC scan, and combined imaging techniques such as bone/Ga-67 scan, WBC/bone marrow scan add complementary role to the radiologic imaging modalities including plain radiography, CT and MRI. F-18 FDG PET imaging also has recently been introduced in diagnosis of infected prosthesis and chronic active osteomyelitis. Selection of proper nuclear medicine imaging method will improve the diagnostic accuracy of infectious and inflammatory bone diseases, based on understading of pathogenesis and radiologic imaging findings.

Malignant bone tumors would be classified as primary malignant bone tumors, secondary malignant bone tumors, and metastatic bone tumors. Primary malignant bone tumors are rare diseases occupying 1% of adult cancers, and 6% of pediatric cancers. The chief complaint of malignant bone tumor patients is pain different from that of malignant soft tissue tumor patients. Diagnostic procedures start with clinical evaluation including current illness, past medical history, family history, and physical examination. Then we take a radiograph first and obtain important and diagnostic clues from it. However pathological diagnosis and information about the extent of tumor are required to obtain a more definite diagnosis and staging. Examinations for detection of local and systemic tumor extent are scintigraphy, computed tomography (CT), magnetic resonance imaging, and positron emission tomography-CT. If the clinical and radiographic information suggests aggressive or malignant bone tumor, the patient should be referred to a bone tumor specialist without further evaluations.

BACKGROUND: Bone marrow scintigraphy using Tc-99m labeled antigranulocyte antibody has been reported to be able to evaluate bone marrow status. We have performed antigranulocyte antibody scan and hematopoietic activity in order to identify bone marrow status in patients with hematologic diseases. METHODS: Sixty-nine patients were enrolled in this study from October 1995 to May 1997. Images were acquired at four and twenty-four hour after injecion of 20mCi 99mTc labeled antigranulocyte antibody (BW 250/183). Patients were divided into four groups according to scintigraphic findings, those with increased marrow uptake (marrow expansion), decreased uptake, focal defect and normal findings. RESULTS: Leukemias and myelodysplastic syndromes frequently showed bone marrow expansion. Seventeen of 21 patients (81%) with AML, and all of ALL and biphenotypic leukemias showed bone marrow expansion. Five of 6 with CML, all Hodgkin's diseases and 3 of 4 MDS also showed marrow expansion. In contrast, all aplastic anemia patients showed decreased marrow uptake, and extra-axial noted in 2 patients with aplastic anemia. All of ten patients with multiple myeloma and 2 of 4 (50%) with Hodgkin disease showed focal marrow defects. Three of 11 with non-Hodgkin lymphoma and 4 of 21 with AML also showed focal marrow defects. CONCLUSION: Bone marrow scintigraphy using antigranulocyte antibody has clearly demonstrated the distribution of bone marrow in various hematologic diseases. Thus, it seems to be a useful method in the assessment of bone marrow status in patients with hematologic disease.

7.Whole body bone scintigraphy correlation in a case of multiple extramedullary plasmacytoma.

Multiple extramedullary (soft tissue) plasmacytoma is a rare neoplasm of plasma cells. This is a case of a 63-year-old male who presented with back pain and a one month history of a painful, progressively growing mass at the right anterior chest wall. Since radiographs and computed tomography of the chest showed lytic lesions on the ribs and L4 compression deformity, the patient was referred for whole body bone scintigraphy to evaluate the remainder of the skeleton. Bone scintigraphy revealed osteoblastic lesions and osteolytic lesions in the thoracic cage. Diagnosis of plasmacytoma was established by biopsy and confirmation of microscopic characteristics and immunohistochemical staining.

BACKGROUND/AIMS: Liver scintigraphy is a useful tool in evaluating the chronic liver disease, even though it is less sensitive to detect a mass lesion in the liver than ultrasonography, computed tomography (CT), or magnetic resonance imaging (MRI). We evaluate the clinical usefulness of liver scintigraphy in patients with liver cirrhosis by comparing with the clinical and biochemical indices. METHODS: Liver scintigraphy was taken beginning 20 minutes after the intravenous injection of 370 MBq of Tc-99m phytate. Images were obtained in multiple views with a gamma camera (Basicam(R), Siemens). The size of the liver, left lobe enlargement, inhomogeneity of radioactivity, the size of the spleen, the extrahepatic uptake were evaluated on liver scintigraphy. The compared clinical indices were serum albumin level, serum bilirubin level, INR (international normalized ratio) for prothrombin time, the presence of hepatic coma, and esophageal varix. RESULTS: Forty four patients (M:F=24:20) were included. The extrahepatic uptake such as bone marrow and splenic uptake was positively correlated with the level of serum bilirubin and negatively correlated with the level of serum albumin. The size of the spleen, inhomogenous liver uptake, hypertrophy of left lobe was positively correlated with the degree of esophageal varix. The size of the liver was negatively correlated with that of esophageal varix. CONCLUSION: We suggest that scintigraphic findings in liver scintigraphy could be used in the evaluation of patients with liver cirrhosis not only to diagnose cirrhosis but also to know the severity of cirrhosis.

BACKGROUND: We compared indomethacin therapy with the more aggressive approaches of anti-cancer chemotherapy and surgery in the treatment of isolated Langerhans cell histiocytosis (LCH) of bone in children. METHODS: Comparisons were made with respect to healing of the lesion without recurrence, time to radiological healing of the lesion, time to functional recovery, and complications related to treatment. RESULTS: Complete radiologic healing of the lesion (mean, 15.3 months) and functional recovery (mean, 5.6 months) were observed in all patients treated with either approach. No significant differences were noted in the time to complete radiologic healing or the time to functional recovery between the two groups. There were no recurrences with either approach until the last follow-up (mean, 56 months). Complications were common with anti-cancer chemotherapy, but indomethacin was well-tolerated. CONCLUSIONS: Indomethacin seems to be effective for treating isolated LCH of bone in children. Hence, morbidities associated with aggressive treatment approaches such as anti-cancer chemotherapy or surgery can be avoided.

Scurvy is very rare disease in industrialized societies. Nevertheless, it still exists in higher risk groups including economically disadvantaged populations with poor nutrition, such as the elderly and chronic alcoholics. The incidence of scurvy in the pediatric population is very low. This study reports a case of scurvy in a 5-year-old girl with cerebral palsy and developmental delay based on MRI findings.
