Skeletal-extraskeletal angiomatosis is defined as a benign vascular proliferation involving the medullary cavity of bone and at least one other type of tissue. It has also been known as cystic angiomatosis in which multiple cystic lesions are scattered diffusely throughout the skeleton often with similar angiomatous changes in other tissues, usually the spleen. A case of skeletal angiomatosis i...

BACKGROUND AND PURPOSE Rhabdoid meningioma (RM) is a recently described variant of malignant meningioma, with radiologic features currently not well characterized in the medical literature. The purpose of this study was to describe and characterize clinical features and imaging findings associated with RM. MATERIALS AND METHODS CT (n = 8) and MR (n = 15) images of 15 patients (4 men and 11 wo...

Although the occurrence of bone changes in von Recklinghausen's disease is uncommon, the incidence is difficult to determine, as mild cases are less likely to seek advice, particularly if the disease is already in the family. Holt and Wright (1948) thought it was greater than a previously estimated figure of 7%. Of the bony deformities, scoliosis appears to be the commonest. Weiss (1921) descri...

pleuropulmonary blastoma (ppb) is a rare, malignant intrathoracic tumor that occurs mostly in children before 5 years old. it consists about 15% of all primary pediatric pulmonary tumors and shows various mesenchymal components. its presentations are nonspecific and common symptoms include fever, cough, chest pain, respiratory distress, and pulmonary infection. ppb should be considered in the d...

Introduction: The nevoid basal cell syndrome (Gorlin’s Syndrome) is a dominant autosomic disorder, characterized by multiple basal cell carcinomas, odontegenic keratocysts, dural calcifications, bone and face malformations, tumors including meduloblastoma and ovaric fibromas, as well as different degrees of mental retardation. Characteristic imagine findings of the Gorlin’s Syndrome are odontog...

hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhanci...

BACKGROUND Long-term severe hyperparathyroidism leads to thinning of cortical bone and cystic bone defects referred to as osteitis fibrosa cystica. Cysts filled with hemosiderin deposits may appear colored as "brown tumors." Osteitis fibrosa cystica and brown tumors are occasionally visualized as multiple, potentially corticalis-disrupting bone lesions mimicking metastases by bone scintigraphy ...

Cytokines released by immune system cells play an important role in cyst enlargement. This study aimed to determine, by ELISA, the levels of granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin 3 (IL-3), and IL-6 in fluid and tissue from human radicular cysts. GM-CSF was found in 42.8% of the fluid samples (164.3 pg/mL) and IL-6 in 92.8% (641.4 pg/mL). No IL-3 was detected in ...

AIM The aim of the study was to evaluate the effect of Low-Level Laser Therapy (LLLT) on bone formation in cystic defects following cyst enucleation. PATIENTS AND METHODS The sample was composed of sixteen patients with enucleated maxillary bony cystic lesions. With an age range from 20 - 44 grouped as eight Laser and eight Control patients. Laser group was subjected to low intensity diode la...
