Primary sinonasal melanoma is a rare disease. We present a case of melanoma in sinuses without abnormal F-FDG activity anywhere in the scanned portion of the body. In further assessment, C-choline PET/CT revealed high activity in the paranasal sinuses, skull base, and adjacent brain, in agreement with the high signal on contrast-enhanced T1-weighted MRI scan, which suggested the residual tumor.

Optimizing skull base defect repair: leveraging the reused nasoseptal flap as a reliable material.

Eur Arch Otorhinolaryngol

Purpose: The escalating number of endoscopic skull base procedures necessitates exploring additional materials to reduce postoperative cerebrospinal fluid (CSF) leaks in revision or staged surgeries. This study evaluates the effectiveness of reused nasoseptal flaps (NSFs) in such clinical scenarios.

Methods: A retrospective review was conducted on patients who previously underwent surgery involving NSFs and later had revision or secondary skull base surgeries via endoscopic endonasal approaches (EEAs) at a tertiary medical center.

Purpose: Pituitary adenomas, despite their histologically benign nature, can severely impact patients' quality of life due to hormone hypersecretion. Invasion of the medial wall of the cavernous sinus (MWCS) by these tumors complicates surgical outcomes, lowering biochemical remission rates and increasing recurrence. This study aims to share our institutional experience with the selective resection of the MWCS in endoscopic pituitary surgery.

Chordomas are a low-to-intermediate-grade slow-growing subtype of sarcoma, but show propensity to grow and invade locally with recurrence and metastasis in 10-40% of cases. We describe the first case of spontaneous regression of a solid tumor (histologically and immunohistochemically proven chordoma) after COVID-19. A female patient with clival chordoma underwent occipitocervical fixation prior to tumor resection.

Hydrolethalus Syndrome: A Case of a Rare Congenital Disorder.

Department of Dentistry, Faculty of Dentistry, "Vasile Goldiș" Western University of Arad, 94-96 Revolutiei Blvd., 310025 Arad, Romania.

This is a fatal case of multiple complicated congenital anomalies displaying several symptoms consistent with hydrolethalus syndrome. The newborn's phenotype is characterized by a combination of serious anatomical abnormalities such as open-book cerebral hemispheres, defective lobulation of the lungs (one lobe on the left, two on the right), a smaller right kidney, a smooth cerebral surface, and a specific keyhole-shaped defect in the skull base, primarily associated with hydrocephalus.

Background: Meningioma represents the most common intracranial tumor in adults. However, it is rare in pediatric patients. We aimed to demonstrate the clinicopathological characteristics and long-term outcome of pediatric meningiomas (PMs).
