A Unique Technique for Precise Targeting in Treatment of Rare Bifocal Intraosseous Ganglion Cysts of the Talus: A Case Report and Review of the Literature.

BACKGROUND This article presents a rare case of 2 separate intraosseous ganglion cysts of the talus in a 51-year-old man, treated with a unique technique of precise lesion targeting to avoid extensive bone loss and minimize articular chondral injury of the talus. CASE REPORT Two separate intraosseous ganglion cysts of the talus were diagnosed in a 51-year-old man with chronic ankle pain. A single straight-line incision with an entry point through the talonavicular joint was created to spare the precarious blood supply of the talus network.

Internal carotid artery origin of the anterior cerebral artery: A rare anatomic intracranial arterial variation in a child with morning glory disc anomaly and moyamoya vascular pattern; case report and review of literature.

Morning glory disc anomaly (MGDA) characterizes a congenital dysgenetic disorder of the optic disc, coexisting with arterial intracranial abnormalities, including Moyamoya vascular disease, a significantly rare disease in the European populations. We report a 2.5-year-old female child from Greece previously diagnosed with MGDA, who presented with right-hand paresis, accompanied by focal epileptic spasms, followed by an episode of brief absence seizure, as well as some arm clonic spasms.

Arthroscopic Treatment of Luxatio Erecta Humeri Associated with Greater Tuberosity Fracture, Bankart Lesion, and Partial Rotator Cuff Tear: A Case Report.

BACKGROUND Luxatio erecta humeri (LEH) is a rare injury present in only 0.5% of shoulder dislocations. Much of the relevant literature is focused on the initial management and proper reduction techniques, although the prevalence of associated injuries can reach 80%.

An MRI study of immune checkpoint inhibitor-induced musculoskeletal manifestations myofasciitis is the prominent imaging finding.

Objective: To assess: (i) the prevalence, and clinical and imaging characteristics of immune checkpoint inhibitor (ICI)-induced musculoskeletal immune-related adverse events (ir-AEs) in a prospective manner and (ii) whether serum levels of cytokines associated with the Th1/Th2/Th17 response are differentially expressed in patients with and without musculoskeletal Ir-AEs.

Methods: All patients treated with ICI who developed musculoskeletal manifestations were referred to the Rheumatology Department, and an MRI of the involved area(s) was performed.

Results: During the study period, a total of 130 patients were treated with ICIs.

An ischemic stroke as the presenting manifestation of rapidly progressive primary angiitis of central nervous system in a 17-year-old boy.

Background: Childhood primary angiitis of the central nervous system (cPACNS) is an increasingly recognized inflammatory brain disease in children.

Case Presentation: We present a case of a 17-year-old boy with recurrent ischemic events over a short time period. Diagnosis of angiography positive cPACNS was made based on neuroimaging findings while secondary causes or mimics of CNS vasculitis were meticulously excluded.

Bilateral Supratentorial Subdural Hematomas after Craniotomy for Posterior Fossa Tumor Removal.

A 69-year-old man was admitted to the emergency department with headache and dizziness. He was submitted to brain computed tomography (CT) which showed a tumor in the right cerebellar hemisphere, findings which were subsequently confirmed with magnetic resonance imaging (MRI). He underwent a paramedian suboccipital craniotomy for removal of the mass.

Frequent Benign, Nontraumatic, Noninflammatory Causes of Low Back Pain in Adolescents: MRI Findings.

Introduction: Low back pain (LBP) is common in children and adolescents. There are many factors that cause LBP, including structural disorders, degenerative changes, Scheuermann's disease, fractures, inflammation, and tumors. Magnetic Resonance Imaging is the gold standard for diagnosing spinal abnormalities and is mandatory when neurological symptoms exist.

Massive bilocular spinal cord intramedullary lipoma of the thoracic spine.

Spinal cord intramedullary lipomas are rare, comprising 2% of intramedullary tumours. They are more often associated with spinal dysraphism, while lipomas not associated with spinal dysraphism are even less frequent, accounting for 1% of cases. The pathogenesis of spinal cord intramedullary lipomas remains unclear.

Giant cell tumor of the tendon seath of the tendinous insertion in pes anserinus.

A 56-year-old woman with a palpable lump in the medial surface of her left knee was referred for diagnostic workup with magnetic resonance imaging. The lesion was pathogically confirmed to be a giant cell tumor of the tendon seath. The MR features of the lesion are presented.

OPTIMISATION OF PATIENT DOSE AND IMAGE QUALITY IN ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY: A PHANTOM-BASED EVALUATION.

A phantom-based study is presented aiming to optimise patient dose and image quality (IQ) in endoscopic retrograde cholangiopancreatography procedures, utilising a fluoroscopy system equipped with a flat panel detector. The patient thickness was simulated with various polymethyl methacrylate slabs, whilst IQ was evaluated using the Leeds test object. The main factors evaluated were phantom thickness, distance between phantom and detector, field of view and pulse rate.
