Pediatric meningioma with rhabdoid features developed at the site of skull fracture: illustrative case

Sho Takata, Akira Tamase, Yasuhiko Hayashi, Osamu Tachibana, Katsuaki Sato, and Hideaki Iizuka

Meningiomas account for approximately 20% of intracranial tumors and typically occur in adults. Pediatric meningiomas are rare, and their occurrence is reported to occur in 2.2% of all intracranial meningiomas. They tend to be associated with atypical locations, higher histopathological grades, and aggressive behaviors. 1 Tumorigenesis of a meningioma after head trauma has been deliberated upon for many years. 2–4 In 1938, post-traumatic meningioma was first described by Cushing and Eisenhardt, who reported a causal relationship between head trauma

Frontal intradiploic encephalocele in a 44-year-old male patient: illustrative case

Baran Atli, Sebastian Rath, Johannes Burtscher, Johannes A. Hainfellner, and Simon Hametner

, dermoid cysts, or metastasis. The absence of overt malignancy features, the preserved integrity of the outer skull table, and the presence of leptomeninges in the lesion may imply benign cystic lesions such as intraosseous leptomeningeal cysts or intradiploic arachnoid cysts. 14 However, none of these lesions enclose the cerebral parenchyma, which is characteristic of the intradiploic encephalocele. Here, we describe a case of a right frontal intradiploic encephalocele in a 44-year-old man with localized meningothelial proliferation reminiscent of meningioma and trauma

Traumatic rupture of thoracic epidural capillary hemangioma resulting in acute neurologic deficit: illustrative case

Reilly L. Kidwell, Lauren E. Stone, Vanessa Goodwill, and Joseph D. Ciacci

CD31, an endothelial cell marker. 1 Grossly, capillary hemangiomas appear as a reddish purple mass with a rich vascular network and must be carefully dissected from feeding vessels to maintain hemostasis. Radiologically, these present as a well-defined mass with T1 signal isointense to the spinal cord and hyperintensity on T2. 5 They are often confused preoperatively with meningiomas or large nerve sheath tumors. To our knowledge, this case is the first report of a traumatic thoracic epidural capillary hemangioma rupture. Thoracic capillary hemangiomas are

Traumatic cervical spine subarachnoid hemorrhage with hematoma and cord compression presenting as Brown-Séqüard syndrome: illustrative case

-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
