White Epidermoid Cyst: An Illustrative Case.

White epidermoid cysts are a rare type of epidermoid cyst that appears hyperintense on T1 weighted magnetic resonance imaging (MRI) and are known for their characteristic pearly white outer appearance on gross pathology. White epidermoid cysts are not common findings; therefore, this illustrative case report was written to highlight the characteristics, progression, radiological evaluation, and management of a patient who presented to our center. This case report emphasizes the importance of determining the proper diagnosis to treat and manage the condition appropriately and avoid potential future complications.

Change in management for digital subtraction angiography-identified false-positive traumatic vertebral artery injury.

Background: For patients with suspected traumatic vertebral artery injury (TVAI), CT angiography (CTA) is the first-line screening modality. Digital subtraction angiography (DSA) serves as the confirmatory diagnostic imaging, and is the gold standard for cerebrovascular injury assessment, due to its higher sensitivity and specificity. Among patients with TVAI based on CTA who have undergone follow-up DSA, this study aims to investigate how diagnostic information with additional imaging affects clinical management.

Elective outpatient middle meningeal artery embolization for chronic subdural hematoma is safe.

Background: Middle meningeal artery embolization (MMAE) is a safe and effective treatment for chronic subdural hematoma (cSDH); however, the appropriate level of postoperative care is unknown.

Objective: To evaluate whether elective MMAE for cSDH could be safely performed in an outpatient setting.

Methods: This was a multicenter, retrospective study of patients with cSDH who underwent elective MMAE.
