Cerebellar ganglioglioma mimicking the radiographic appearance of Lhermitte-Duclos disease: A case report and review of literature.

BACKGROUND

Lhermitte-Duclos disease (LDD) is a rare condition that typically presents with signs and symptoms of cerebellar dysfunction and elevated intracranial pressure. Magnetic resonance imaging (MRI) plays a pivotal role in the diagnosis of LDD as its characteristic "tiger-striped" appearance is believed to be diagnostic enough to eliminate the need for histopathological examination. We present a case of cerebellar ganglioglioma mimicking the distinct MRI appearance of LDD.

CASE REPORT: A 46-year-old female patient presented with increasing dizziness, blurred vision and headaches. An MRI scan demonstrated the presence of heterogeneous, nonenhancing mass with the characteristic "tiger-striped" appearance of LDD. However, after tumor resection, histopathological examination demonstrated that the tumor histological architecture resembles that of gangliogliomas rather than LDD, leading to an altered diagnosis and therapeutic approach.

CONCLUSION

LDD's "tiger-striped" might not be as unique as previously thought, and histopathological examination is essential for proper diagnosis, treatment and follow-up.
