Jugular foramen schwannomas are a rare event with an estimated 200 cases reported in the literature. These tumors represent only 2.9% to 4% of all intracranial and less than 1% temporal bone lesions [1,2].

This paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

Ewing Sarcoma is the second most common primary bone cancer. To date, only a few cases of cutaneous have been published. We present unique case Sarcoma, which presented as blue to violaceous mass on young woman’s chest. The lesion clinically did not align with previous reports but pathology and immunohistochemical stains confirmed diagnosis. Because may masquerade benign tumors, dermatologists ...

Introduction One of the important applications of nuclear physics in medicine is the use of radioactive elements as radiopharmaceuticals. Metastatic bone disease is the most common form of malignant bone tumors. Samarium-153-ethylene diamine tetramethylene phosphonate (153Sm-EDTMP) as a radiopharmaceutical is used for pain palliation. This radiopharmaceutical usually emits beta particles, which...

We compared MRI, CT and bone scintigraphy in the examination of experimentally produced metastatic bone tumors. Three Japanese white rabbits with VX-2 bone tumor were used. T1 weighted (T1W) and T2 weighted (T2W) images were obtained in each MRI examination. All the tumors distributed from the bone marrow to the extraosseous region. T2W images were the best to detect the extraosseous tumors. CT...

Chondromyxoid fibroma (CMF) is a rare benign cartilaginous tumor with a predilection for the bones of lower extremities and about one fourth of the tumors involve the foot.Radiologically, an eccentric lytic lesion with well defined margins is seen in the metaphysis of the bone. We hereby, report an 18 yr old young male who presented to Orthopedic Outpatient Department, JN Medical College, Aliga...

Positron emission tomography (PET) using [ 18 F]fluorodeoxyglucose (FDG) is a useful modality to examine many kinds of tumors, including primary bone tumors. Malignant bone tumors show higher FDG accumulation than benign tumors and earlier reports mention that FDG-PET can differentiate malignancy from benignancy; however, some benign bone tumors present with high FDG accumulation, which increas...

OBJECTIVE The present study was done to find out the frequency of malignant tumors of bone and to categorize the prevalence of various histological types of osseous malignancies with respect to age, sex and site of origin. SETTING This study included consecutive cases of malignant bone tumors, which were diagnosed in the department of pathology at the Aga Khan University Hospital, Karachi dur...
