AI Article Synopsis
- An 18-year-old man experienced severe neck pain and other symptoms following a mild head injury from a traffic accident.
- MRI indicated a hematoma in the cisterna magna, extending into the subdural space near the spinal cord, which developed eight days later.
- The case highlights the effectiveness of MRI in diagnosing localized hematomas at the craniovertebral junction and explores the possible cause of the hemorrhage, such as a ruptured bridging dorsal vein.
Article Abstract
An 18-year-old man suffered severe neck pain, signs of meningeal irritation, and dysesthesia of his left breast and left arm after mild head injury incurred in a traffic accident. On the next day, magnetic resonance imaging(MRI) revealed a hematoma in the cisterna magna, and it extended into the posterior spinal subdural space. Eight days after admission, MRI demonstrated the hematoma on the right posterior aspect of the spinal cord at the level of craniovertebral junction. These MRI findings suggested a ruptured bridging dorsal vein from the spinal cord to the occipital or marginal sinus. The usefulness of MRI for diagnosis of localized hematoma around the craniovertebral junction and the mechanism of this hemorrhage are discussed.

Lymphatic filariasis is an uncommon condition in Hong Kong and is currently considered as one of the neglected tropical diseases by the World Health Organization. Blood tests are available for diagnosis of acute infections, but false negative results can occur with chronic manifestations of lymphatic filariasis. We present a case which illustrates how radiological imaging can help with diagnosis of lymphatic filariasis.

This study explored the risk factors associated with hydrocephalus incidence and evaluated the effectiveness of surgical treatments in managing this condition. Patients with PBSH were retrospectively evaluated, identifying clinical and radiological characteristics. A multivariate logistic regression model was used for analyses.

: Subarachnoid hemorrhage (SAH) is a life-threatening cerebrovascular condition that triggers a robust inflammatory response and cerebral vasospasm. This study aimed to evaluate the effects of anakinra, an interleukin-1 receptor antagonist, and tocilizumab, an interleukin-6 receptor antagonist, on inflammation and vasospasm in an experimental rat SAH model. : Forty male Sprague Dawley rats (200-250 g) were randomly assigned to five groups: control, SAH, SAH + anakinra (ANA), SAH + tocilizumab (TCZ), and SAH + anakinra + tocilizumab (ANA+TCZ).

Article Synopsis
- A 2-year-old female Golden Retriever exhibited sudden non-ambulatory paraparesis after initially unremarkable examinations, prompting further investigation.
- MRI revealed an intradural-extramedullary mass causing significant spinal cord compression, indicating a hemorrhagic process, and CSF analysis showed signs of inflammation.
- Following surgery for decompression, the dog showed gradual improvement and regained mobility, and the diagnosis of steroid responsive meningitis-arteritis (SRMA) was supported by clinical findings and treatment response.

Hydrocephalus commonly occurs after subarachnoid hemorrhage (SAH) and is associated with increased morbidity and disability in patients with SAH. Choroid plexus cerebrospinal fluid (CSF) hypersecretion, obliterative arachnoiditis occluding the arachnoid villi, lymphatic obstruction, subarachnoid fibrosis, and glymphatic system injury are considered the main pathological mechanisms of hydrocephalus after SAH. Although the mechanisms of hydrocephalus after SAH are increasingly being revealed, the clinical prognosis of SAH still has not improved significantly.
