Haemorrhagic conversion of infectious myelitis in an immunocompromised patient.

A 28-year-old man recently diagnosed with HIV (CD4 19 cells/mm3, viral load 3.6 million copies/mL, not on highly active antiretroviral therapy on initial diagnosis at outside hospital), disseminated histoplasmosis, shingles and syphilis presented with paraplegia developing over 3 days. Spine MRI demonstrated a longitudinally extensive cord lesion extending from C3 to the tip of the conus. Brain MRI was consistent with meningoencephalitis. Cerebrospinal fluid findings were notable for positive varicella zoster virus (VZV) and cytomegalovirus (CMV) PCRs as well as a Venereal Disease Research Laboratory titre of 1:2. Patient was started on treatment for VZV and CMV meningoencephalitis, neurosyphilis and high-dose steroids for infectious myelitis. Repeat spine MRI demonstrated subacute intramedullary haemorrhage of the cervical cord. He was ultimately discharged to a skilled nursing facility for long-term intravenous antiviral therapy and rehabilitation. After 59 days in the hospital, his neurological exam remained grossly unchanged, with flaccid paraplegia and lack of sensation to fine touch in his lower extremities.
