Oxaliplatin-induced papilledema: Rare case report.

Papilledema is the presence of bilateral optic disc edema in the presence of raised intracranial pressure and often is symmetric. We report a case of a 70-year-old male with rectal carcinoma on chemotherapy presented with minimal drop in visual acuity. The patient has bilateral disc edema and investigations including computed tomography and cerebrospinal fluid opening pressure were normal and no evidence of brain metastasis has been found.

Peripheral primitive neuroectodermal tumor of the orbit in Graves' ophthalmopathy - A rare presentation.

Graves' ophthalmopathy is the most common cause of both unilateral and bilateral proptoses in adults. Peripheral primitive neuroectodermal tumor (pPNET) is a small round cell malignant lesion of neuroectodermal origin which very rarely affects the orbit. In this case report, we have discussed about a young woman with existing Graves' ophthalmopathy who presented with worsening proptosis; computed tomography imaging revealed an irregular mass lesion in the right orbit without bone erosion.
