Bilateral Diffuse Uveal Melanocytic Proliferation in a Patient with Recurrent Frontal Lobe Meningioma.

BACKGROUND

Bilateral diffuse uveal melanocytic proliferation (B-DUMP) is a paraneoplastic disorder that may be seen in patients with a known malignancy but more commonly is seen in those without any history of cancer. It leads to multiple uveal tumors with exudative retinal detachment along with thickening of the choroid and generally carries a poor prognosis. Its etio-pathogenesis is poorly understood but is said to involve factors secreted by the systemic malignancy that lead to proliferation of melanocytes in the uvea.

METHODS

We report the presentation and management of a female with history of treated frontal lobe meningioma who presented with neovascular glaucoma along with B-DUMP and was found to have recurrence of the meningioma on neuro-imaging.

CONCLUSIONS

Central nervous system meningiomas can cause B-DUMP and management of the malignancy may lead to partial resolution of posterior segment manifestations of B-DUMP.
