Relapsing symptoms post herpes simplex virus 1 (HSV) encephalitis (HSVE) usually occur a few weeks after viral therapy and represent either 1) a true viral relapse of HSVE (CSF PCR positive for HSV, new necrotic lesions on brain MRI, and response to acyclovir therapy) or 2) a disorder postulated to be immune-mediated (CSF negative for HSV, no new necrotic lesions, and no response to acyclovir). It has been suggested that this immune-mediated disorder may be related to NMDA receptor (NMDAR) antibodies, and we recently reported a child in whom relapsing symptoms post HSVE were the presentation of anti-NMDAR encephalitis. We report an adult with this disorder, demonstrate that synthesis of NMDAR antibodies began after HSVE, and show that relapsing symptoms were due to steroid-responsive anti-NMDAR encephalitis.

Introduction: Excision and primary anastomosis (EPA) urethroplasty is the standard treatment for traumatic urethral strictures, but managing them remains challenging for urologists. Identifying factors leading to EPA urethroplasty failure benefits both patients and surgeons. This study aims to analyze risk factors for urethral stricture recurrence after one-year follow-up of EPA urethroplasty.

Background: The differential diagnosis between benign and malignant thyroid nodules continues to be a major challenge in clinical practice. The rising incidence of thyroid neoplasm and the low incidence of aggressive thyroid carcinoma, urges the exploration of strategies to improve the diagnostic accuracy in a pre-surgical phase, particularly for indeterminate nodules, and to prevent unnecessary surgeries. Only in 2022, the 5th WHO Classification of Endocrine and Neuroendocrine Tumors, and in 2023, the 3rd Bethesda System for Reporting Thyroid Cytopathology and the European Thyroid Association included biomarkers in their guidelines.

Chondromyxoid fibroma (CMF) in the foot is a rare condition. We report a case of CMF in a 7-year-old girl, affecting the distal phalanx of the great toe. Radiographs revealed a lytic lesion involving the entire distal phalanx, with destruction of both the medial and lateral cortices, while the articular surfaces remained intact.

Persistent primitive olfactory arteries (PPOAs) are a rare variant of the anterior cerebral artery (ACA). Cerebral aneurysms may arise in the PPOA; most are saccular and on the unilateral PPOA. We report a 66-year-old male with bilateral PPOAs and a fusiform aneurysm on the left side detected at a health check-up.
