Introduction: Previous studies have reported a decreased risk of dementia with herpes zoster vaccination. Given this background, this systematic review and meta-analysis aimed to investigate the association between herpes zoster vaccination and the risk of dementia.
Methods: We searched five databases until November 2023 for case-control, cross-sectional, or cohort studies investigating the association of herpes zoster vaccination and dementia.
Dyke-Davidoff-Masson syndrome (DDMS) was first described in 1933 as a cerebral condition of hemispheric atrophy characterized clinically by contralateral hemiparesis, facial-asymmetry, seizures, and mental retardation. Neuroimaging findings include asymmetric thickening of the calvarium and enlargement of frontal and ethmoid sinuses. There have been 21 reported cases described in the literature with the syndrome undiagnosed until adult age, likely due to less severe or absent clinical findings or symptoms as described in the case presented in this report.

A 36-year-old-man with a history of cervical radiculopathy presented with cauda equina syndrome. An MRI was performed for further evaluation demonstrating multiple intradural, extramedullary enhancing lesions in the thoracic and lumbar spine, as well as extra-axial enhancing lesions with involvement of the lateral ventricles and posterior fossa.

In the peri-operative period, brain shift occurs as the consequence of events related to the brain surgery which results in post-operative lead deformation. To quantify post-operative 3-dimensional DBS lead deformation after implantation.

In addition, these structures might be encountered with endovascular procedures within the transverse sinus and are now readily seen on imaging. Therefore as anatomic studies of these structures are scant, the current study aimed to better elucidate these structures within the transverse sinus via a morphologic study in cadavers.

Insult to the thalamus can, therefore, result in complex syndromes involving sensation, cognition, executive function, fine motor control, emotion, and arousal, to name a few. Specific territories in the thalamus that are supplied by deep cerebral arteries have been shown to correlate with clinical symptoms.

We selected consecutive patients with TLE and normal MRI undergoing temporal lobe resection between April and September 2015. Clinical features, imaging, and functional data were reviewed.

Typical examples of these injuries include muscle contusions, lacerations, sprains, and delayed onset muscle soreness. For other less common traumatic muscle conditions (exertional compartment syndrome, muscle herniation, and traumatic denervation), the clinical findings are often subtle or ambiguous and MRI will indicate the correct diagnosis.

However, noninvasive methods can be useful in the detection and characterization of these lesions. The noninvasive diagnosis of liver lesions is usually achieved with contrast material-enhanced computed tomography and magnetic resonance (MR) imaging.

Pulmonary embolism (PE) as a complication of ECT has been rarely reported. We describe a nonfatal case of PE that developed during ECT in a 50-year-old man with depression, hypertension, and diabetes.

Subjects And Methods: Twenty-five patients with urinary bladder cancer diagnosed on conventional cystoscopy underwent MR imaging of the pelvis. Patients were examined without external bladder filling or administration of IV contrast medium.
