Lhermitte-Duclos disease presenting with positron emission tomography-magnetic resonance fusion imaging: a case report

Lhermitte-Duclos disease with excessive calcification in a septuagenarian: A case report

RATIONALE

Lhermitte-Duclos disease (LDD), or dysplastic cerebellar gangliocytoma (DCG), is a rare tumor originating from the cerebellar cortex. LDD is a benign neuroglial tumor with uncertain prognosis. Over 200 cases have been reported in the literature mostly in the form of case reports. Thus, we present a spectacular case of LDD with excessive calcification in a female septuagenarian.

PATIENT CONCERNS

A 72-year-old female presented with progressive dizziness for 8 months and suffered a head and sacrococcygeal region injury 20 days prior to her admission in our neurosurgery department.

DIAGNOSIS

Computed tomography scan showed a right nonspecific cerebellar mass with striated calcification. Magnetic resonance imaging revealed a right "tiger-striped" alteration of the cerebellar cortex. H&E staining revealed a low grade glial neural tumor which was consistent with the diagnosis of LDD or DCG.

INTERVENTION

The lesion was total resected.

OUTCOMES

The patient recovered well and the cerebellar dysfunctional symptoms subsided 3 months after the operation and 2 years follow-up revealed no recurrence of the lesion and no neurological deficits.

LESION

We postulate that the calcification of LDD is age-related and the pathogenesis of disease often observed in young adulthood.
