Retinochoroidal toxoplasmosis in a patient with cerebral post-transplant lymphoproliferative disease of Hodgkin’s type: a diagnostic challenge

Toxoplasmosis is a relatively rare complication in renal transplant patients and can pose diagnostic challenges, especially when it manifests as an ocular inflammation. Authors hereby report an unusual case of a 57-year-old male who developed retinochoroidal toxoplasmosis after 15 years of renal transplant, the diagnoses of which were challenging as the patient was also a known case of cerebral post-transplant lymphoproliferative disease (PTLD) of Hodgkin's type, which misled the ophthalmologists towards a clinical diagnosis of ocular PTLD. Histopathology examination of the enucleated eye revealed numerous toxoplasmosis cysts within the retina and choroid. No ocular PTLD was observed.
