Background: The incidence of symptomatic hemangioblastoma of the posterior fossa during pregnancy is extremely low. Previous reports have noted that pregnancy seems to aggravate the clinical course of intracranial tumors, but little is known about the possible reasons. Various theories have been proposed to explain the rapid neurologic deterioration of hemangioblastoma patients during pregnancy; however, the pathophysiologic behavior and histogenesis of this vascular tumor are still not well understood.
Case: A case of cerebellar hemangioblastoma was diagnosed during pregnancy. Urgent surgery was required due to rapid development of obstructive hydrocephalus and brainstem compression.
Conclusion: Obstetricians and neurosurgeons should be aware of the rare clinic entity of hemangioblastoma during pregnancy. Surgery might be indicated as soon as the tumor becomes symptomatic.

Intracranial cystic lesions such as hemangioblastoma (HB) are commonly found incidentally; however, they can be difficult to diagnose because they require various differential diagnoses. A contrast-enhanced mural nodule on magnetic resonance imaging (MRI) is typical and can be diagnosed preoperatively; however, some small nodules cannot be visualised and only cysts may be seen, complicating preoperative diagnosis. In such cases, thorough observation of the cysts is necessary for a definitive diagnosis.

Article Synopsis
- Von Hippel-Lindau is a rare genetic disorder with an autosomal dominant inheritance pattern, leading to multiple vascular tumors, especially in the brain, eyes, and organs.
- The disease can manifest at any age, with retinal tumors often being one of the first signs; MRI and fluorescein angiography are key diagnostic tools.
- A case study highlights a woman in her late 30s with vision loss, revealing various eye and kidney abnormalities, including cystic lesions in her brain and elevated urine protein levels.

Article Synopsis
- * Spinal cord hemangioblastomas make up a small percentage (1.1% to 2.4%) of central nervous system tumors, typically presenting as single tumors in adults around their 40s, while they are rare in children, especially those without VHL syndrome.
- * The thoracic spinal cord is the most common location for these tumors, which can lead to serious symptoms like spinal cord compression and bleeding, despite being classified as benign.

Article Synopsis
- * Five pediatric patients with VHL-associated hemangioblastomas were treated with belzutifan, leading to improvements in tumor size and vision for those with retinal lesions, and benefits in neurologic symptoms for patients with intracranial tumors.
- * The treatment resulted in minor side effects, such as grade 1-2 anemia in four patients, and suggests belzutifan could be a promising therapy for young patients with these tumors.
