Ruptured Vertebral Artery Dissecting Aneurysm Concurrent with Spontaneous Cervical Internal Carotid Artery Dissection: A Report of Three Cases and Literature Review.
Multiple dissections rarely occur with ruptured vertebral artery dissecting aneurysms (VADAs). Here we report 3 cases of ruptured VADA concurrent with spontaneous cervical internal carotid artery (ICA) dissection. ⋯ The clinical management of patients with SAH and cervical ICA dissection is complicated. Given that rebleeding of VADA is fatal, achieving hemostasis is the priority. Subsequently, ICA revascularization should be considered to manage ischemic stroke or aneurysmal changes, depending on the SAH stage. In contrast to the typically benign course of sporadic cervical ICA dissection, hemodynamic changes related to SAH and internal trapping of a VADA may exacerbate the cervical ICA dissection. Careful follow-up may be required for cervical dissecting aneurysms in this specific pathological setting.

Spinal arteriovenous malformation associated with Parkes Weber syndrome: Report of two cases and literature review.
To present 2 cases of Parkes Weber syndrome (PWS) with spinal arteriovenous malformation (AVM) and discuss the radiologic features and clinical treatment with literature review. ⋯ Awareness of the association between spinal AVM and PWS is essential for radiographic screening of spinal lesions with myelopathy or intracranial subarachnoid hemorrhage. Clinical therapeutic strategy should be multidisciplinary and individualized on the basis of vasculature and lesion behavior.

Pineal region tumors represent a rare and histologically diverse group of lesions. Few studies are available to guide management and the outcomes after stereotactic radiosurgery (SRS). ⋯ SRS is a safe modality for the management of pineal region tumors. Its specific role is highly dependent on tumor histology. As such, all efforts should be made to obtain a reliable histologic diagnosis.

Rhabdoid Meningioma Arising Concurrent in Pulmonary and Intracranial with a Rare Malignant Clinical Progression: Case Report and Literature Review.
Rhabdoid meningioma (RM) is an unusual variant of meningioma, classified as World Health Organization grade III. Although its recurrence is common, extracranial metastasis is rare and usually misdiagnosed. The transfer mechanism and pathway are ambiguous; once the metastasis occurs, the prognosis is poor, and there is no effective management. The present case is the first report of concurrent intracranial and pulmonary RM with rapid and widespread metastasis. We hope this report can serve as a helpful reference for clinicians and radiologists. ⋯ Intracranial RM is a relatively rare tumor with the potential for wide intracranial and extracranial transfer. Cystic components and necrosis can be seen in this type of meningioma. Metastatic meningioma should be kept in mind when dealing with isolated lung lesions. This case report may serve as a helpful reference for clinicians and radiologists.

Review Case Reports
Malignant cerebral swelling after cranioplasty due to ipsilateral intracranial vasculopathy: case report and literature review.
Cranioplasty is a well-established surgical operation that is used worldwide for patients with skull defects following decompressive craniectomy (DC). However, in some cases, potentially fatal complications may occur, such as malignant cerebral swelling after uneventful cranioplasty. ⋯ Our case demonstrates for the first time that ipsilateral intracranial vasculopathy is a risk factor for malignant cerebral swelling after cranioplasty. Patients with traumatic brain injury with suspected intracranial vasculopathy should undergo a comprehensive vascular evaluation before cranioplasty to help prevent malignant cerebral swelling.
