Abstract
ObjectiveTo illustrate three different ophthalmic presentations of cryptococcal meningitis (CM). IntroductionCM is the most common manifestation of extra-pulmonary cryptococcosis. Intracranial hypertension occurs in up to 75% of patients with CM and is associated with increased mortality. CM can present to the ophthalmologist as vision loss, papilledema, abducens palsy, and/or other cranial neuropathies. Participants and MethodsWe report three cases, two C. neoformans and one C. gattii, highlighting the various CM presentations. The first was a woman immunosuppressed following kidney transplantation in whom idiopathic intracranial hypertension (IIH) was initially suspected. The second was a man immunocompromised by previously undiagnosed HIV/AIDS who presented with signs and symptoms of increased intracranial pressure. The third case is an immunocompetent man with bilateral disc edema and an incomplete macular star diagnosed with presumed neuroretinitis. Further evaluation revealed positive CSF cryptococcal antigen with culture positive for C. gattii. ConclusionsOphthalmologists should be aware that cryptococcosis can mimic more benign etiologies including IIH and neuroretinitis. Additionally, C. gattii, an emerging organism, can infect immunocompetent patients. In contrast to the typical treatment of increased ICP, serial lumbar punctures are recommended while acetazolamide and surgical CSF shunting may be harmful.
