🧠 PILOCYTIC ASTROCYTOMA vs HEMANGIOBLASTOMA
Two classic posterior-fossa lesions that can look remarkably similar on MRI: cyst + enhancing mural nodule.
🔵 Pilocytic Astrocytoma (PA)
• Usually children/adolescents
• Well-circumscribed cerebellar lesion
• Cyst + enhancing mural nodule
• Cyst wall may enhance
• Usually less vascular; flow voids uncommon
• High ADC, without marked diffusion restriction
🔴 Hemangioblastoma (HB)
• Typically young/middle-aged adults
• Cyst + intensely enhancing mural nodule
• Highly vascular → prominent flow voids
• Markedly elevated rCBV
• Cyst wall typically non-enhancing
• Consider VHL, especially with multiple lesions or young age
🔑 Radiology pearl: A cerebellar cystic lesion with a brilliantly enhancing mural nodule + prominent flow voids/high rCBV should raise suspicion for hemangioblastoma.
🔎 Concise differential diagnosis:
• Pilocytic astrocytoma
• Hemangioblastoma
• Metastasis
• Medulloblastoma
• High-grade glioma
• Ependymoma
• Abscess/infective lesion
📚 Based on concepts from Youmans & Winn Neurological Surgery and clinical localization principles from DeJong’s Neurologic Examination.
⚠️ Diagnostic disclaimer: This post is intended for medical education only. MRI features can overlap between posterior-fossa tumors, and imaging findings alone may not establish a definitive diagnosis. Final diagnosis requires correlation with the complete clinical history, appropriate imaging sequences, and, when indicated, histopathological examination by qualified specialists.
