AI Article Synopsis
- A rare case of a 15-month-old boy with a cerebellar pilocytic astrocytoma presented with massive intracranial hemorrhage, including intratumor bleeding, subarachnoid hemorrhage, and subdural hematoma, highlighting a unique medical scenario.
- MRI indicated the presence of a tumor in the left cerebellar hemisphere, requiring emergency surgery for near-total tumor removal.
- This case is significant as it documents a previously unreported combination of symptoms and suggests that the bleeding occurred due to the tumor leaking into surrounding spaces.
Article Abstract
Introduction: Massive intracranial hemorrhage is a very rare initial presentation of cerebellar pilocytic astrocytomas. There are no reports in the medical literature on a cerebellar pilocytic astrocytoma presenting with intratumor bleeding (ITB), subarachnoid hemorrhage (SAH), and subdural hematoma (SDH).
Case Report: A 15-month-old boy presented with lethargy and nausea to our hospital. Magnetic resonance imaging showed a mass with ITB at the left cerebellar hemisphere in addition to SDH in the posterior fossa and SAH at the interpeduncular cistern. The patient underwent emergency surgery. On incising the dura, we found SDH, the tumor was visible at the cerebellar cortex, and near total removal followed. Microscopic examination of tissue sections revealed a pilocytic astrocytoma.
Discussion: The authors' case is the first report with a presentation including ITB, SAH, and SDH. The presumed mechanism of the SAH and SDH was leaking of the ITB into subarachnoid and subdural spaces.

Cerebellar pilocytic astrocytoma: predictors of recurrence based on MRI morphology-a single-centre experience.
Childs Nerv Syst
December 2024
Department of Neurosurgery, Medical University of Vienna, Währinger Gürtel 18-20, 1090, Vienna, Austria.
Purpose: We aimed to present our surgical experience and the impact of a solid or cystic morphology of cerebellar pilocytic astrocytoma (cPA) on surgery and the risk for a re-resection.
Methods: We retrospectively analyzed all children operated at our institution between 2009 and 2023 for cPA. Tumours were categorized into 4 groups: (i) cystic PA without cyst wall enhancement, (ii) cystic PA with cyst wall enhancement, (iii) solid tumour, (iv) and solid tumour with central necrosis.

The frequency and duration of imaging surveillance in children and adolescents with pediatric low-grade gliomas (pLGGs) aims for the early detection of recurrence or progression. Although surveillance of pLGGs is performed routinely, it is not yet standardized. The aim of the current review is to provide a comprehensive synthesis of published studies regarding the optimal frequency, intervals, and duration of surveillance.

Article Synopsis
- Pediatric posterior fossa tumors have complex diagnostic challenges due to their diverse features; this study evaluates the effectiveness of diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) measurements to aid in tumor classification.* -
- The study analyzed 59 patients under 18 with diagnosed posterior fossa tumors, measuring ADC values and ratios from tumor and normal brain tissues, finding significant differences in ADC values between various tumor types (pilocytic astrocytomas, ependymomas, and medulloblastomas).* -
- Results indicate that ADC metrics can effectively differentiate these tumors, though the study suggests that future research should involve larger patient groups and advanced imaging methods to enhance diagnostic accuracy.*

Article Synopsis
- * This systematic review followed PRISMA guidelines to analyze 21 studies out of 249 citations screened, highlighting radiomics' potential to differentiate medulloblastomas from other tumors and identify their subtypes.
- * The findings suggest that while radiomics shows promise for predicting survival rates in medulloblastoma patients, further research is needed to fully assess its clinical value.

Article Synopsis
- Neuroepithelial tumors resembling pilocytic astrocytoma have been reclassified by the WHO as high-grade astrocytoma with piloid features (HGAP), highlighting their unique characteristics and rarity.
- An 83-year-old woman experienced progressive lower-extremity weakness, leading to the discovery of a neuroepithelial tumor in the conus medullaris, which is an uncommon site for this type of tumor.
- The case emphasizes the need for clinicians to consider HGAP in differential diagnoses for spinal cord masses, as it represents a novel classification of a rare condition.
