Clinical Perspective on Dysplastic Gangliocytoma of the Cerebellum (Lhermitte-Duclos Disease).

BACKGROUND

Dysplastic gangliocytoma of the cerebellum, also called Lhermitte-Duclos disease (LDD), is known as a rare, benign brain tumor. Around 200 cases have been reported.

CASE DESCRIPTION: Here we introduced a newly diagnosed adult case with intratumoral hemorrhage. Then we reviewed 18 cases diagnosed in our institute, including 12 adults and 6 children.

CONCLUSIONS

Preoperative diagnosis based on magnetic resonance imaging is 50% in adults and 16.7% in pediatrics. Diagnostic tiger stripes are not always seen in pediatric cases. The prognosis of the disease is good if total resection can be achieved. Further examinations for PTEN mutation and other comorbidities are recommended.
