Pediatric angiocentric glioma with acute intracerebral hemorrhage: A case report with 36 months follow-up

BACKGROUND: Angiocentric glioma (AG) is an extremely rare intracranial tumor that was first described in 2005 and identified as a special type of intracranial tumor in 2007 by the WHO, which mainly affects children and young adolescents. Epilepsy is the main presentation; therefore, it was recognized as a seizure-related tumor in the past. Here, we report a case of AG with acute intracerebral hemorrhage (ICH) as the first symptom who never had a seizure onset. CASE DESCRIPTION: A 3-year-old girl with the right limb weakness was admitted to our hospital 4 h after onset in 2018. Computed tomography showed a hematoma of about 20 ml accompanied by a hyper/iso-dense spheroid lesion located in the sub-cortex of the left parietal lobe. Magnetic resonance image (MRI) showed signs of hypointense signal in T1, T2, and fluid-attenuated inversion recovery sequence, distinct enhancement of this tumefactive lesion in the contrast-enhanced sequence. Thus, the admission diagnosis was neoplasm with acute ICH. A gross total resection of the tumor was achieved by parietal craniotomy. The histopathological diagnosis was AG. No signs showed tumor recurrence after 36 months of follow-up. CONCLUSION: This is the sole case of AGs with acute intracranial hemorrhage as the first symptom without any kind of epilepsy by far. This case had unique MRI signs that were different from the previous description. This case enriches the clinical and radiological manifestations of AG and reveals that further investigations are needed to further understand AG.
