Is It an Overlooked Injury? Magnetic Resonance Imaging Examination of Occult Talus Lesions Concomitant to Tibial Shaft Fracture.

Long-term studies have shown that 10% to 20% of patients continue to experience ankle pain years after tibial fracture, which causes poor functional results and dissatisfaction. The aim of this study was to show that there could be a talus injury in patients with a tibial shaft fracture and to reveal occult talus lesions with magnetic resonance imaging (MRI) examination. Fifty-two patients with a tibial shaft fracture, with closed epiphyses, not extending to the joint and with no problems in the application of MRI examination were included.

Functional evaluation of secondary renal amyloidosis with diffusion-weighted MR imaging.

Giant cemento-ossifying fibroma of the maxilla.

Introduction: Fibro-osseous lesions of the skull and facial bones are benign tumors, but they can be mistaken for malignant tumors due to their clinically aggressive behavior. Cemento-ossifying fibroma (COF) is a benign fibro-osseous lesion characterized by slow growth and fibrous and calcified tissue content. COFs are locally destructive lesions causing deformities in the bones.

Intramedullary lipoma of the cervico-thoracic spinal cord.

Most of the spinal cord lipomas reported in the literature are intradural extramedullary, and true intramedullary lipomas are very rare. We present a case of intramedullary spinal cord lipoma of the cervico-thoracic region with extensions over many spinal segments. Magnetic resonance (MR) examination showed an intramedullary lipoma of the cervico-thoracic spinal cord of both high T1 and T2-weighted signal intensity and suppression on fat saturation sequence.

Aneurysmal bone cyst of the calcaneus.

Aneurysmal bone cysts (ABCs) are benign, non-neoplastic, expansile, vascular, locally destructive lesions. The lesion may arise de novo (65%) or secondarily (35%) in pre-existing benign or malignant lesions (giant cell tumor, osteoblastoma, chondroblastoma, angioma, and others). The calcaneus is a rare localization for ABC, comprising only 1.

Spinal inflammation by magnetic resonance imaging in patients with ankylosing spondylitis: association with disease activity and outcome parameters.

Magnetic resonance imaging (MRI) has major contribution in early diagnosis of ankylosing spondylitis (AS). As it is difficult to determine disease activity owing to the lack of close relation between laboratory tests, clinical findings and imaging, MRI has been used as an objective outcome measure. The aim of this study is to investigate the relation between spinal MRI findings with disease activity and other outcome measures.
