patients with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (melas) present with recurrent and partially reversible neurological deficits. lesions of melas classically cause a signal change in both the grey and white matter, predominantly in the occipital and parietal lobes. these lesions mimic infarction. here, we reported a case of melas with rare neuroimaging finding...

OBJECTIVE To analyze the role of core needle biopsy of axillary lymph nodes with suspected metastases from breast cancer and to correlate the imaging and histologic findings. MATERIAL AND METHODS We retrospectively studied 74 patients diagnosed with breast cancer who underwent ultrasound-guided core needle biopsy of axillary lymph nodes with characteristics suggestive of metastases on ultraso...

Osteointegration is a direct structural relationship between the bone and implant surface, properly osseointegration can function without mobility. We aim to evaluate this process using serial radiological examinations, where characteristics such as sclerosis cortical-periosteal thickening will be investigated. A retrospective analytic-observational study was conducted on 96 patients after ceme...

We have examined gender differences of cortical thickness using a 3-D surface-based method that enables more accurate measurement in deep sulci and localized regional mapping compared to volumetric analyses. Cortical thickness was measured using a direct method for calculating the distance between corresponding vertices from inner and outer cortical surfaces. We normalized cortical surfaces usi...

INTRODUCTION: Alendronate (Aln) is a bisphosphonate agent that has been widely used for the treatment of osteoporosis. Recently, several studies have suggested an association between long-term use of Aln and the occurrence of low-energy subtrochanteric/femoral shaft (ST/FS) fractures. Previous studies described characteristic imaging features of this atypical fracture including transverse orien...

Caffey’s disease was characterized by a triad of symptoms, irritability, soft tissue swelling, and underlying cortical bone thickening. It mostly occurs before the first 5 months life in infancy. The knowledge this pathology essential as it masquerades wide range diseases including acute osteomyelitis, tumors, trauma, battered baby syndrome (child abuse), hypervitaminosis a, scurvy, infantile m...
