Convexity subarachnoid haemorrhage: a practical guide.

Area of Science:

• Neurology
• Radiology

Background:

• Atraumatic convexity subarachnoid haemorrhage is bleeding in the brain's sulci without brain tissue damage.
• Common causes include reversible cerebral vasoconstriction syndrome, cerebral sinus venous thrombosis, posterior reversible encephalopathy syndrome, and cerebral amyloid angiopathy.

Purpose of the Study:

• To detail the clinical and radiological characteristics of non-traumatic convexity subarachnoid haemorrhage.
• To explore its diverse presentations, etiologies, management strategies, and patient outcomes.
• To highlight key clinical considerations and potential challenges through case examples.

Main Methods:

• Review of clinical case data.
• Analysis of radiological imaging findings.
• Literature review of relevant conditions and their management.

Main Results:

• Detailed description of clinical symptoms and radiological signs associated with atraumatic convexity subarachnoid haemorrhage.
• Identification and categorization of various underlying causes.
• Summary of current treatment approaches and prognostic factors.

Conclusions:

• Non-traumatic convexity subarachnoid haemorrhage has varied presentations and causes.
• Understanding these features is crucial for accurate diagnosis and effective management.
• Clinical vignettes aid in recognizing important diagnostic and therapeutic nuances.
