Intraocular medulloepithelioma is an extremely rare unilateral intraocular tumor arising from the nonpigmented ciliary epithelium. Medulloepitheliomas may be classified as benign and malignant and as teratoid and nonteratoid tumors. As a rule a long latency period occurs after first symptoms until the final diagnosis of a medulloepithelioma is made. Differential diagnosis includes in particular unilateral retinoblastoma. Intraocular medulloepithelioma may occur as masquerade-syndrome simulating uveitis. We present 10 patients with intraocular medulloepithelioma. In 7 of these patients the eye had to be enucleated. Metastasis did not occur, but epiretinal tumor seeding did occur in one patient. In one of the 3 not enucleated eyes, ruthenium-106 brachytherapy could salvage the tumor containing eye.

A 13-month-old, neutered, male, domestic shorthair cat was referred with a history of progressive paraparesis, proprioceptive ataxia, and lumbar spinal pain. Neurological examination revealed non-ambulatory paraparesis consistent with L4-S1 myelopathy. Magnetic resonance of the thoracolumbar spinal cord identified a dorsal intradural extramedullary space-occupying lesion extending from L5 to L6.

Metastatic tumors to the eye and eyelid are generally seen in patients with disseminated metastases in the setting of advanced disease. Occasionally, they can present as the first sign of occult malignancy. The choroid is the most common site of intraocular metastases secondary to its dense vascular supply.

Introduction And Importance: Medulloepithelioma is the second most common primary intraocular malignant tumor in children but is often diagnosed late, which worsens the prognosis.
Case Presentation: We are reporting a 6-year-old boy presenting with a ciliary body (CB) teratoid malignant medulloepithelioma (TMM), which was missed at the initial presentation. We added our case to the 97 previously reported cases in our literature review that were confirmed by cytological or histopathological examination.
