Abstract
Background
Dysembryoplastic neuroepithelial tumours (DNETs) are benign brain tumours that most commonly arise at supratentorial sites. The cerebellum is an extremely rare location for DNETs. We report a case of cerebellar DNET along with literature review.
Case description
A girl aged 2 years and 3 months presented with gait instability. Imaging examination showed a very large cystic-solid mass with mixed densities/signal intensities in the cerebellum. The entire lesion was successfully removed, and the patient achieved a good prognosis.
Conclusion
Cerebellar DNET lacks characteristic imaging-based signs, and the diagnosis mainly relies on pathological examination. However, this diagnosis should be considered when a cerebellar lesion in child consists of cystic-solid mass with mixed densities/signal intensities.
