Spinal extradural arachnoid cysts (SEACs) are rare and usually asymptomatic, and they usually do not require surgical treatment. If symptoms manifest, however, surgical treatment is required. A 25-year-old male patient complained of impotence upon admission. Magnetic resonance images (MRIs) of his lumbar spine showed a SEAC located longitudinally from the T11 to L3, which was accompanied by thecal sac compression. Verifying the location of the dural defect is crucial for minimizing surgical treatments. Cystography, myelography, and lumbar spine MRI were conducted to locate the leak in real-time; however, it was not found. Hence, the location of the cerebrospinal fluid leak was estimated based on cystography, computed tomography, myelography, and MRI findings. We suggest that the region with the earliest contrast-filling, as well as the middle and widest area of the cyst, may correspond to the location of the dural defect.

Pseudomeningoceles are among the most common postoperative neurosurgical complications, usually presenting in the early postoperative period and often responding well to nonsurgical management. Here, we present a case of a giant cranial pseudomeningocele that developed three years after parasagittal meningioma resection, without any known risk factors. Despite conservative measures, the pseudomeningocele grew significantly over two years, reaching 22 cm along its long axis.

Traumatic cerebrospinal fluid (CSF) leakage from skull base fractures increases the risk of bacterial meningitis, which is associated with a high mortality rate in adults, and commonly results in severe neurological outcomes. While most cases of CSF leakage occur within three months post-injury and generally resolve spontaneously, delayed-onset meningitis remains a challenging complication. Herein, we report a rare case of severe bacterial meningitis with an intraventricular abscess one year following a frontal skull base fracture, despite no CSF leak.

Background: Spinal epidural arachnoid cysts (SEACs) are rare, non-neoplastic pathologies that can cause compressive myelopathy. Preoperative identification of the exact fistula location is crucial for minimally invasive management.
Methods: This single-center retrospective study included 27 patients with SEACs who underwent "double-needle puncture myelography" to precisely localize the fistula before minimally invasive surgery.

Background: The authors report the first case of thoracic interdural spinal cysts presenting as radiculopathy attributed to overdrainage-related cervical venous plexus enlargement. This case emphasizes the importance of considering interdural spinal cysts and cerebrospinal fluid overdrainage in the differential diagnosis of radiculopathy.
Observations: A 37-year-old male patient with a history of orthostatic headache presented with bilateral deltoid muscle atrophy consistent with C5 radiculopathy.

Article Synopsis
- Tinnitus affects about 25% of older adults, with non-pulsatile tinnitus usually lacking structural causes, while pulsatile tinnitus may indicate underlying health issues that can be identified through imaging.
- A thorough clinical evaluation is essential for determining the appropriate diagnostic strategy and imaging is warranted for unilateral non-pulsatile tinnitus or any pulsatile tinnitus cases.
- Imaging methods like MRI or CT are used based on the type of tinnitus and any accompanying symptoms, with special attention needed for potential serious conditions in cases of pulsatile tinnitus.
