PURPOSE To describe the characteristic CT, MR, and angiographic features of giant serpentine aneurysms and discuss their endovascular treatment. METHODS Thirteen patients with giant serpentine aneurysms were studied at our institution in the last 3 years. They all underwent CT and MR studies as well as cerebral angiography. More recently, some of the patients were studied with MR angiography....
Medulloblastoma with extensive nodularity is a rare subtype of the most common malignant childhood brain tumor and has been associated with more favorable prognosis. The authors report the case of a 10-month-old girl with a posterior fossa tumor of excessive nodularity with decreased diffusivity on diffusion-weighted magnetic resonance imaging sequences and robust grape-like postgadolinium cont...
Calcifying aponeurotic fibroma is a rare, benign fibroblastic tumor. The lesion has a propensity for local invasion and a high recurrent rate. Therefore, accurate preoperative diagnosis and complete excision are important to prevent the recurrence of the tumor after surgical removal. However, radiographic and magnetic resonance imaging findings of calcifying aponeurotic fibroma have been extrem...
BACKGROUND Ollier's disease is a non-hereditary, benign bone tumor which is usually characterized by presence of multiple radiolucent lesions (enchondromas) in the metaphysis of long bones with unilateral predominance. The disease is a rare clinical entity with 1/100000 occurrence in early childhood. Patients mostly present with multiple hard swellings and deformity of the tubular bones special...
We present a case of solitary fibrous tumor of pleura (SFTP) in a 63-year-old male. Clinical manifestations of this entity, including paraneoplastic syndromes, are discussed, albeit absent in our presented case. Furthermore radiographic findings and pathologic correlations are provided. SFTP remains a rare neoplasm for which radiographic features are suggestive yet nonspecific, and immunohistoc...
repeating x-ray radiographs, as a common problem in radiology units, represent additional, non-billable costs due to increased film, chemistry, and equipment use as well as increased personnel time. furthermore, patients receive additional radiation exposure from repetitions and must remain on the premises until the second exam is completed. compounding the overt negative financial impact on th...
introdouction: the aim of the present study was to investigate image magnification in digital panoramic radiography and assess the effect of anatomical sites on the magnification in both males and females. materials and methods: in this retrospective study, digital panoramic radiographs of 48 patients with 202 implants were investigated. implant diameter and length were measured on panoramic ra...
OBJECTIVES The clinical management of meningioma is guided by tumor grade and biological behavior. Currently, the assessment of tumor grade follows surgical resection and histopathologic review. Reliable techniques for pre-operative determination of tumor grade may enhance clinical decision-making. METHODS A total of 175 meningioma patients (103 low-grade and 72 high-grade) with pre-operative...
Context: The essential role of a general dental practitioner is recognizing the nature of the oral cavity lesions. Periapical lesions, which are observed in radiographs of patients, may have odontogenic or nonodontogenic origins. This review aimed to study differential diagnosis of common and important periapical lesions. Evidence Acquisition: English-language literature were searched by manual...
OBJECTIVE To describe skeletal findings in patients with Kniest dysplasia, focusing on osseous abnormalities that have not been characteristically associated with this disorder. MATERIALS AND METHODS This was a retrospective study. The radiographs of four patients with known Kniest Dysplasia were evaluated by three musculoskeletal radiologists. RESULTS Bilateral radial head dislocations and...
