Galloping ophthalmoplegia and numb chin in Burkitt lymphoma.

A 57-year-old man developed complete bilateral ophthalmoplegia over a period of 10 days, together with bilateral facial pain and numbness of the chin. He had no other clinical manifestations. Findings on brain magnetic resonance imaging and spinal fluid formula from the first lumbar puncture were normal, but cerebrospinal fluid flow cytometry disclosed a kappa restriction monoclonal B-cell population, indicating malignant lymphoma.

Metastatic neuroblastoma presenting with binocular blindness from intracranial compression of the optic nerves.

A 2-year-old boy with blindness as an isolated symptom was found to have no light perception binocularly because of compression of both optic nerves by a neuroblastoma infiltrating the walls of the optic canals and medial sphenoid bone. Imaging disclosed a primary tumor near the kidney and multiple osseous metastases. Although neuroblastoma commonly causes blindness by metastasis to the orbit, it rarely causes bilateral blindness from intracranial compression of the optic nerves.
