Parathyroid adenoma presenting with multiple Brown tumors in an adolescent patient.

Parathyroid glands are endocrine glands that secrete parathyroid hormone (PTH) and regulate calcium-phosphor metabolism. The overexpression of PTH is called hyperparathyroidism (HPT), and is classified as primary, secondary, and tertiary. Primer HPT (PHPT) is the most common cause of parathyroid adenomas (80%-85%).

Subperiosteal hemorrhage due to a distal femoral physeal fracture in a neonate.

Femoral physeal fractures have been rarely reported as a birth-related injury. As the plain radiograph findings are variable, the diagnosis may be challenging. In this case report, we describe a male neonate presenting with periosteal elevation at the left distal femur.

Effects of short and long term electromagnetic fields exposure on the human hippocampus.

The increasing use of mobile phones may have a number of physiological and psychological effects on human health. Many animal and human studies have reported various effects on the central nervous system and cognitive performance from of exposure to electromagnetic fields (EMF) emitted by mobile phones. The aim of the present study was to evaluate the effects of mobile phones on the morphology of the human brain and on cognitive performance using stereological and spectroscopic methods and neurocognitive tests.

Contribution of 3-T Susceptibility-Weighted MRI to Detection of Intraarticular Hemosiderin Accumulation in Patients With Hemophilia.

Objective: The purpose of this study was to assess the feasibility of 3-T susceptibility-weighted imaging (SWI) for detecting intraarticular hemosiderin accumulation in patients with hemophilia.

Subjects And Methods: Forty-one joints in 24 patients with hemophilia were imaged with conventional MRI and SWI sequences. Two experienced musculoskeletal radiologists and one general radiologist (reader 3) interpreted the images for hemosiderin accumulation.

Quantitative assessment of muscular stiffness in children with cerebral palsy using acoustic radiation force impulse (ARFI) ultrasound elastography.

Purpose: To evaluate the feasibility of quantitative analysis of muscle stiffness in the medial gastrocnemius muscle (GCM) by acoustic radiation force impulse (ARFI) ultrasound elastography in children with spastic cerebral palsy (CP).

Methods: Seventeen children with spastic CP and 25 healthy children participated in the study between the years 2016-2017. The medial GCM in the CP group was assessed using the Modified Ashworth Scale (MAS) by a physiatrist.

Quantitative assessment of muscle stiffness with acoustic radiation force impulse elastography after botulinum toxin A injection in children with cerebral palsy.

Purpose: Our objective in this study was to assess the changes in medial gastrocnemius muscle (GCM) stiffness after botulinum toxin A (BTA) injection in children with cerebral palsy (CP) by using acoustic radiation force impulse (ARFI) elastography and to research the usability of this technique in clinical practice.

Materials And Methods: Twenty-four spastic lower extremities of 12 children with CP were assessed. BTA injection treatment was applied to the medial GCM.

Accuracy of Percutaneous CT-Guided Spine Biopsy and Determinants of Biopsy Success.

Purpose: The purpose of this study was to investigate the accuracy of CT-guided spine biopsy as well as the factors that may influence its success.

Methods And Materials: A total of 170 CT-guided biopsies performed on 156 patients with vertebral lesions were retrospectively analyzed. The accuracy of the biopsies was evaluated by comparing the final diagnosis with the biopsy results for patients who underwent surgery or with six-month clinical and radiological follow-up findings for patients who did not have surgery.

Vaccine-induced myositis with intramuscular sterile abscess formation: MRI and ultrasound findings.

Although limb swelling is a well-known complication of vaccination, its rarity and wide band of differential diagnosis of limb swelling make it a diagnostic challenge. In this case report, we describe three cases of vaccine-induced myositis with intramuscular sterile abscess formation in patients with limb swelling and their magnetic resonance imaging and ultrasonography findings. Both radiologists and clinicians should be familiar with this rare entity, its clinical and imaging spectrum, and follow-up strategies.

Osteoskeletal manifestations of scurvy: MRI and ultrasound findings.

Scurvy has become very rare in the modern world. The incidence of scurvy in the pediatric population is extremely low. In the pediatric population, musculoskeletal manifestations are more common and multiple subperiosteal hematomas are an important indicator for the diagnosis of scurvy.

Psoas abscess with septic arthritis of the hip: a case report.

Psoas abscess associated with septic arthritis of the hip is unusual in infants. A 12-month-old infant presented with the complaints of fever, left hip pain and limp. Magnetic resonance imaging revealed left psoas abscess accompanied by septic arthritis of the hip.

Distribution and evaluation of bone and soft tissue tumors in the middle Black Sea Region.

Objective: The aim of this study was to evaluate the characteristics of bone and soft tissue tumors operated on at the Department of Orthopedics and Traumatology at Ondokuz Mayıs University Faculty of Medicine Hospital between January 1987 and January 2012.

Methods: This descriptive study retrospectively evaluated 1,925 patients hospitalized with a preliminary diagnosis of tumor. Patients were analyzed for age, gender, tumor incidence and localization.

Early spondyloarthropathy: scintigraphic, biological, and clinical findings in MRI-positive patients.

There are no specific diagnostic tests or a gold standard method for measuring disease activity and outcome in spondyloarthropathies (SpA). Many different methods have been developed to assess the signs and symptoms in SpA. The aim of this study was to evaluate the value of scintigraphy, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and Bath Ankilosing Spondylitis Disease Activity Index (BASDAI) in the evaluation of disease activity in early axial SpA diagnosed with magnetic resonance imaging (MRI).

Melanotic neuroectodermal tumor of infancy of the femur.

Melanotic neuroectodermal tumor of infancy (MNTI) is a rare neoplasm that often occurs during the first year of life. More than 90% of MNTIs occur in the head and neck region, with most on the anterior part of the maxillary ridge. MNTI has also been reported in the mediastinum, thigh, foot, shoulder, and gonads.

Acquired von Willebrand syndrome in a patient with Ewing sarcoma.

Acquired von Willebrand syndrome is a rare bleeding disorder with clinical and laboratory features closely resembling to hereditary von Willebrand disease. The syndrome may accompany various conditions, including malignant disorders, most often with Wilms tumor and adrenal cell carcinoma. In this report, the authors present a patient with AvWS in association with Ewing sarcoma for the first time in the literature.

The effects of section thickness on the estimation of liver volume by the Cavalieri principle using computed tomography images.

Estimation of liver volume using routine CT scans has been described previously. We have, however, not found a gold standard study which analyzes the effect of section thickness on the estimation of liver volume using CT images. In the present study, five normal livers obtained from cadavers were scanned using a Spiral CT Scanner (Xpress/GX Toshiba, Tocigi-Ken) in the horizontal plane.

Neurologically normal complete asymmetric lumbar spine duplication.

Spine duplication, which is at the severe end of the split cord malformation, is rarely seen. Radiographic, CT, and MR images of a 15-year-old girl who had lower back pain showed asymmetric lumbar spine duplication with spinal cord tethering secondary to a filum lipoma in the sacrum. Despite gross spinal abnormalities, the patient was neurologically intact and has been followed up with conservative treatment.

Evaluation of the patients with renovascular hypertension after percutaneous revascularization by Doppler ultrasonography.

Objective: Evaluation of the effectiveness of percutaneous revascularization is based primarily on clinical criteria, and laboratory findings rather than direct investigation of luminal width. The purpose of this study was to evaluate the success of endovascular revascularization with serial Doppler ultrasound (US) examinations.

Methods And Material: 19 patients (14 were atherosclerotic, five were with fibromuscular dysplasia) with suspected renovascular hypertension treated by percutaneous revascularization were included in a prospective study.
