Myxomas are a heterogeneous group of mesenchymal tumors. Soft tissue myxomas are divided into myocardial, intramuscular, juxta-articular, superficial, aggressive, and nerve sheath myxomas. Although benign, myxomas have site-specific biologic behavior and syndromic associations, which can influence prognosis and management. In addition, myxomas need to be distinguished from malignant neoplasms, such as myxofibrosarcomas, low-grade fibromyxoid sarcomas, myxoid liposarcomas, and peripheral nerve sheath tumors. While myxomas can occur throughout the body, these tumors arise more commonly in the thigh, shoulder, buttocks, and upper extremity, and less often in the head and neck. Rarely, myxomas can arise in a periocular location, typically in the conjunctiva and eyelid skin. In this case report, we present a patient with recurrent intramuscular myxoma of the eyelid and discuss the differential diagnosis and syndromic associations of this neoplasm. To our knowledge, there have been no prior reports of intramuscular myxoma of the eyelid and orbit.

Carcinoma of unknown primary (CUP) comprises 2-5% of cancer diagnoses worldwide, with a prevalence that has modestly declined with increased availability of advanced diagnostic tools such as next-generation sequencing (NGS). This case presentation illustrates the possibilities and gaps that remain with improving diagnostic capabilities in identifying and effectively treating CUP. This is the case of a rapidly enlarging right axillary mass without a primary tumour site and histological evaluation demonstrating a poorly differentiated neoplasm.

Objectives: While lumbar puncture (LP) remains gold standard for assessing intracranial pressure (ICP), LP can be difficult to perform and lead to complications. Noninvasive correlations for elevated ICP via ocular ultrasound (OUS) have shown mixed results. The primary objective of this study is to identify the frequency and test characteristics of the crescent sign on OUS for elevated ICP.

Large hemispheric infarction (LHI) is a severe form of stroke with high mortality and poor outcomes. Ultrasonic optic nerve sheath diameter (ONSD) is considered an effective indicator for intracranial hypertension. Our study aimed to validate the efficiency of ultrasonic ONSD and develop a nomogram to identify LHI patients who have 90-day mortality.

Schwannomas are benign tumors that can develop in any part of a nerve containing Schwann cells. Skull base schwannomas are rare, representing approximately 4% of extracranial schwannomas. Among these, vidian nerve schwannomas are particularly uncommon, with only a few documented cases.
