Positioned along the ventral surface of the pons, proximal superior cerebellar artery (SCA) aneurysms account for only 1.7% of all intracranial aneurysms [1]. Unlike more commonly encountered basilar artery aneurysms, patients often experience good outcomes when treated via endovascular coiling or surgical clipping [1,2].

- Cranial and spinal CSF leaks function differently, with opposing fluid dynamics, indicating distinct causes for each type of leak.
- A 66-year-old woman experienced tension pneumocephalus linked to a CSF leak, requiring cranial surgery; however, she later developed positional headaches and imaging showed complications like subdural hematomas.
- It's crucial for doctors to be vigilant about signs of intracranial hypotension due to spinal leaks following surgical repairs for CSF leaks, especially in cases involving otogenic pneumocephalus.
Introduction: Due to loss of brain buoyancy, spontaneous spinal cerebrospinal fluid (CSF) leaks cause orthostatic headaches but also can cause symptoms indistinguishable from behavioral variant frontotemporal dementia (bvFTD) due to severe brain sagging (including the frontal and temporal lobes), as visualized on brain magnetic resonance imaging. However, the detection of these CSF leaks may require specialized spinal imaging techniques, such as digital subtraction myelography (DSM).
Methods: We performed DSM in the lateral decubitus position under general anesthesia in 21 consecutive patients with frontotemporal dementia brain sagging syndrome (4 women and 17 men; mean age 56.
Article Synopsis
- Intracranial solitary fibrous tumors (ISFTs) are rare tumors from the meninges, often misdiagnosed due to their similarities with other brain tumors, and display unpredictable clinical behaviors despite being previously considered benign.
- A case report details the malignant transformation of an ISFT in a 60-year-old female after radiation therapy, showcasing a progression from a benign diagnosis to a malignant one after recurrence.
- This study highlights the importance of understanding the complex behavior of ISFTs and suggests that their clinical trajectory can vary significantly, which poses challenges for diagnosis and treatment.
Objective: In the current era of modern neurosurgery, the treatment strategies have been shifted to "nerve-preservation approaches" for achieving a higher facial and hearing function preservation rate following facial nerve tumors. We have conducted this novel report on determining the outcome of patients with facial nerve schwannomas (FNS) treated with hypofractionated stereotactic radiosurgery (hfSRS).
Patients: Retrospective chart review of a prospectively maintained database search was conducted.
