Leukaemic infiltration and cytomegalovirus retinitis in a patient with acute T-cell lymphoblastic leukaemia in complete remission.

Clinical Case: A 43-year-old woman in remission from T- cell acute lymphoblastic leukaemia was referred to our hospital with suspected leukaemic retinitis. The funduscopic examination of her left eye revealed multifocal yellow-white peripheral retinitis and retinal haemorrhage. The patient was treated for cytomegalovirus retinitis after an extended haematological investigation showed no abnormalities. Initial improvement was followed by papillitis in the left eye and motility restriction in the right eye. Magnetic resonance and lumbar puncture confirmed leukaemia relapse. Specific treatment was initiated with complete resolution.
Discussion: Ocular involvement may precede haematological leukaemia relapse. Physicians should be alerted when ocular symptoms appear in these cases.
