  1. Artikel ; Online: Simultaneous multiple cervical vessel dissection manifested as pulsatile tinnitus.

    Abstract A previously healthy 43-year-old woman with Wallenberg syndrome, stemming from a left vertebral artery dissection and resulting in a left lateral medulla oblongata infarct, was later diagnosed with simultaneous bi-carotid and right V3 dissection. Seven days post-admission, she experienced sudden right-sided pulsatile tinnitus and exhibited a right-sided carotid murmur. High-resolution vessel wall MR imaging confirmed the new dissections. While spontaneous cervical vessel dissections involving more than two arteries are rare (less than 2% of cases), the prognosis is generally favorable. This case is noteworthy for presenting pulsatile tinnitus as a rare post-stroke dissection recurrence symptom, as documented in medical literature.

    Abstract Vasculitides are characterized by inflammation of the vessel wall, with their categorization relying on clinical and paraclinical manifestations, vessel type, size, distribution, histological attributes, and associated conditions. This review delves into the salient neuroimaging hallmarks of central nervous system vasculitis associated with the most prevalent systemic diseases and highlightings potential pitfalls and diagnostic confounders.

    Abstract Background: Facial palsy is a rare, unexpected complication of temporal lobectomy (TL) for intractable epilepsy. Even without direct manipulation, the facial nerve fibers may be at risk of injury during supratentorial surgery, including TL.
    Observations: The authors presented two cases of facial palsy after unremarkable TL. In the first case, the palsy appeared in a delayed fashion and completely resolved within weeks. In the second case, facial nerve dysfunction was observed immediately after surgery, followed by progressive recovery over 2 years. The second patient had a dehiscence of the roof of the petrous bone overlying the geniculate ganglion, which put the facial nerve at risk of bipolar coagulation thermal injury.
    Lessons: Two major mechanisms could explain the loss of facial nerve function after TL: surgery-related indirect inflammation of the nerve resulting in herpesvirus reactivation and delayed dysfunction (Bell's palsy) or indirect thermal damage to the geniculate ganglion through a dehiscent petrous roof.

    Abstract Increased intracranial pressure is the most common cause of papilledema. Multiple etiologies such as cerebral edema, hydrocephalus, space occupying lesions, infection, and idiopathic intracranial hypertension among others should be considered. Imaging plays a critical role in the detection of pathologies that can cause papilledema. MRI with contrast and CE-MRV, in particular, are key for the diagnosis of idiopathic intracranial hypertension. This review will focus in common and infrequent causes of papilledema, the role of imaging in patients with papilledema as well as its potential mimickers.

    Abstract There is great potential for artificial intelligence (AI) applications, especially machine learning and natural language processing, in medical imaging. Much attention has been garnered by the image analysis tasks for diagnostic decision support and precision medicine, but there are many other potential applications of AI in radiology and have potential to enhance all levels of the radiology workflow and practice, including workflow optimization and support for interpretation tasks, quality and safety, and operational efficiency. This article reviews the important potential applications of informatics and AI related to process improvement and operations in the radiology department.
