Rare case of extracranial chordoid meningioma adjacent to the carotid sheath: illustrative case

Seung W. Jeong, Michael Moran, Shahed Elhamdani, Dorian M. Kusyk, Chen Xu, Kymberly Gyure, and Richard Williamson

Meningiomas are the most common benign tumors arising from within the central nervous system (CNS), comprising approximately 15% of intracranial and 25% of spinal tumors. 1 In rare cases (∼1%), they may arise outside the CNS, 2 and only 0.1% are thought to have metastatic seeding from an intracranial primary tumor. 3 The World Health Organization (WHO) has defined 15 histological meningioma subtypes that fall into a 3-tier grading system that stratifies recurrence risk. 4 Chordoid meningiomas are a rare grade 2 variant with regional histological patterns

The use of an endoscopic endonasal approach for a secondary intraorbital meningioma: illustrative case

Breno W. M. Guedes, Joilson F. de Souza Júnior, Nelson A. D’Avila Melo, João M. B. de Menezes Neto, André Beer-Furlan, and Arthur M. P. Oliveira

Meningiomas are the most frequent benign primary tumors in the central nervous system (CNS), accounting for approximately 36.6% of all cases. 1 They originate from the arachnoid cap cells and may be located anywhere in the CNS, including the extradural compartment. 2–4 An intraorbital site is uncommon and accounts for only 0.2% to 4% of all CNS meningiomas. 5 , 6 Intraorbital meningiomas are classified as primary, secondary, or ectopic. Primary lesions account for 30% of intraorbital meningiomas and originate on the surface of the optic nerve sheath (ONS

Bilateral infraoptic origin of the anterior cerebral artery: illustrative case

Neil Majmundar, Joseph Quillin, James K Liu, and Pankaj K Agarwalla

infraoptic origin of the ACAs encountered during microsurgical resection of a sphenocavernous meningioma. It is important to recognize this variant prior to microsurgical resection in this region to avoid vascular injury. Illustrative Case A 67-year-old female presented with dizziness worsening over a week-long period. Neurological examination did not elicit any focal deficits. Computed tomography (CT) scanning of the head and magnetic resonance imaging (MRI) of the brain demonstrated a large left sphenocavernous meningioma with optic, cavernous, and suprasellar

Ruptured aneurysm of the artery of Davidoff and Schechter: illustrative case

Lane Fry, Frank A. De Stefano, Kevin S. Chatley, Catherine Lei, Jeremy Peterson, and Koji Ebersole

The artery of Davidoff and Schechter (ADS) is a meningeal branch arising from the P1 or P2 segment of the posterior cerebral artery (PCA) that is not well described in the literature. 1 The ADS supplies the dura of the inferomedial portion of the tentorium cerebelli in hemodynamic balance with the artery of Bernasconi and Cassinari. 2 The vessel is typically only identified in the setting of pathology involving the tentorium or posterior falx, often with dural arteriovenous fistulas (DAVFs), 2–6 or meningiomas. 7 Overall, discussion of the ADS in the

Primary hypothyroidism presenting as neuropsychiatric symptoms and pituitary enlargement in a young woman: illustrative case

Shanzay Haider, Kelsey Templeton, S. Bulent Omay, and Silvio E. Inzucchi

Enlargement of the sellar contents in an adult patient is most often associated with neoplasia, with pituitary adenomas accounting for approximately 80%–90% of all such masses. 1 , 2 In fact there is a high prevalence of nonfunctioning, benign pituitary adenomas, the vast majority being microadenomas, reported in up to 20% in the general population. 2–4 Other pathological causes of pituitary enlargement include cysts, craniopharyngiomas, or meningiomas. However, physiological enlargement of the pituitary gland can also occur, stemming from several causes

motor cortex, corona radiata, internal capsule, basal ganglia, brainstem, and spinal cord. 2–4 Several conditions have been reported to cause SFD, including brain tumors (meningioma, glioma), metastases, cerebrovascular accidents (CVAs), cervical disc herniations, demyelinating plaques due to multiple sclerosis (MS), traumatic brain injury, cerebral abscess/contusion, spinal cord compression, and neurocysticercosis. 2–10 Cerebral cases may arise in the parasagittal area because of either direct damage or local mass effect because the medial homunculus of the primary

-related hemorrhages as well as vascular malformations. The majority of tumor-related hemorrhages are typically associated with ependymomas, followed by neurofibromas, astrocytomas, and lastly, meningiomas. 3 Spinal SAH that occur secondary to vascular malformations are frequently caused by arteriovenous malformations (AVMs), spinal angiomas, and aneurysms. 2 Spinal hematomas that occur as a result of trauma are less common. 4 , 5 There are only seven reported cases of traumatic cervical SAH in the literature. 6–12 Treatment is dependent on the patient’s neurological examination

the trapezius and sternocleidomastoid muscles, indicating a proximal compression point. Advanced imaging, such as CT with three-dimensional reconstruction and MRI, was helpful in excluding other causes of extrinsic SAN compression, such as a glomus tumor or meningioma. In these cases of SAN compression from an angulated or calcified styloid process, surgical decompression and styloidectomy led to good results with the recovery of trapezius function despite the prolonged degree of muscle atrophy. It is unclear if the patients will regain significant middle and
