Unlabelled: The etiology of sudden deafness can remain undetermined despite extensive investigation. This study addresses the value of magnetic resonance imaging in the analysis of sudden deafness patients.
Study Design: Transversal cohort.
Material And Method: In a prospective study, 49 patients attended at otolaryngology emergency room of Federal University of Sao Paulo--Escola Paulista de Medicina, from April 2001 to May 2003, were submitted to magnetic resonance imaging.
Results: Magnetic Resonance abnormalities were seen in 23 (46.9%) patients and revealed two tumors suggestive of meningioma, three vestibular schwannomas, thirteen microangiopathic changes of the brain and five (21.7%) pathological conditions of the labyrinth.
Conclusion: Sudden deafness should be approached as a symptom common to different diseases. The presence of cerebellopontine angle tumors in 10.2% of our cases, among other treatable causes, justifies the recommendation of gadolinium-enhanced magnetic resonance use, not only to study the auditory peripheral pathway, but to study the whole auditory pathway including the brain.

Osteoarthritis (OA) is heterogeneous and involves structural changes in the whole joint, such as cartilage, meniscus/labrum, ligaments, and tendons, mainly with short T2 relaxation times. Detecting OA before the onset of irreversible changes is crucial for early proactive management and limit growing disease burden. The more recent advanced quantitative imaging techniques and deep learning (DL) algorithms in musculoskeletal imaging have shown great potential for visualizing "pre-OA.

Objective: To evaluate the postoperative complications and prognosis of renal cell carcinoma (RCC) in a solitary kidney after irreversible electroporation (IRE).
Materials And Methods: A total of 8 patients with 9 RCCs in a solitary kidney treated with computed tomography (CT)-guided IRE from February 2017 to September 2020 were retrospectively analyzed. Follow-up included contrast-enhanced CT or magnetic resonance imaging examinations at 1 day, 1 week, 1 month, 3 months, 6 months, 12 months, and each year after IRE and the evaluation of the incidence of postoperative complications, renal function changes, local tumor recurrence, and metastasis.

Performance: Spontaneous dissections of the cerebral arteries are among the leading causes of stroke in young adults. They result from hemorrhage into the outer layers of the arterial wall, which can lead to stenosis or even complete vessel occlusion. Clinical presentations vary, ranging from localized pain to cerebral ischemic complications.

Purpose Of Review: Psoriatic arthritis (PsA) is a complex heterogeneous inflammatory disease that affects about one-third of patients with psoriasis. PsA leads to significant physical impairment and reduced quality of life. Therefore, early diagnosis and intervention are critical for improving long-term outcomes.
