Paraparesis in a patient with advanced HIV infection: a diagnostic conundrum

In patients with HIV infection, lower limb weakness is a result of the pathological involvement of the brain, spinal cord or peripheral nervous system. The pathological process can be opportunistic infections, nutrient deficiencies, neoplastic infiltration or HIV itself. Here, we present the case of a 50-year-old manual labourer who presented with gradually progressive lower limb weakness, sensory disturbances, impotence and urinary urgency. He was diagnosed with HIV during evaluation. Based on the presentation and other supportive laboratory and radiological evidence, the following differentials were considered: vacuolar myelopathy, amyotrophic lateral sclerosis and myeloradiculopathy. The patient was initiated on antiretroviral therapy, and he showed significant improvement of symptoms on follow-up. We report this case to discuss the diagnostic puzzle.

Atypical HIV-vacuolar myelopathy: a case report

Background Here, we report an atypical HIV-vacuolar myelopathy and search the available medical literature about atypical presentations of human immunodeficiency virus associate vacuolar myelopathy (HIV-VM) and immunoglobulin therapy response. Case A 26-year-old lady who was 4 weeks postpartum presented to us with acute flaccid quadriparesis, with no sensory level. Extensive workup ruled out other causes of myelopathy. She developed a stage 3 acute kidney injury, and MRI showed diffuse cord atrophy involving the lower cervical and thoracic cord. The patient received IV-immunoglobulin, ARVs, and supportive therapy with inadequate response. Unfortunately, she developed nosocomial pneumonia and died. Discussion In HIV-VM, there is spinal cord atrophy, which mainly involves the thoracic cord. In our case, this pathological process also affected the spinal cord's cervical region, leading to flaccid tetraplegia, with high CD4 level, without response to the treatment, including intravenous immunoglobulin. Keynotes Vacuolar myelopathy, HIV, Immunoglobulin therapy, flaccid tetraplegia, hypokalaemia. Renal failure.

HIV-vacuolar myelopathy: an unusual early presentation in HIV

Human immunodeficiency virus (HIV)-vacuolar myelopathy is a late presentation of HIV infection and rarely the presenting symptom. Treatment of HIV-vacuolar myelopathy involves anti-retroviral therapy, but neurological deficits are devastating if diagnosis is delayed. We present a rare case of a patient who presented with HIV-vacuolar myelopathy as the initial presentation in a case of newly diagnosed HIV. The case emphasizes the importance of a high index of suspicion and diagnosis for better outcomes in HIV-vacuolar myelopathy.

HIV-associated vacuolar myelopathy: A rare initial presentation of HIV

HIV-associated vacuolar myelopathy, or AIDS-associated myelopathy, is a rare initial presentation of HIV. One of the common HIV-associated neurocognitive disorders, HIV-associated vacuolar myelopathy presents with advanced immunosuppression in patients and is frequently associated with dementia. However, most cases are subclinical with characteristic findings identified through physical examination and/or imaging modalities. HIV-associated vacuolar myelopathy is characterized by progressive spastic paraparesis, gait disturbance and lower extremity sensory abnormalities including vibratory sensation. Magnetic resonance imaging findings in the spinal cord are abnormal in some patients with HIV-associated myelopathy, characteristically showing spinal cord atrophy at the level of the thoracic spine, but they may also be normal. Unfamiliarity with this as initial presentation of HIV infection may lead to failure to diagnose and intervene appropriately. We present a case of newly diagnosed HIV with myelopathy and dementia with minimal spinal cord involvement on magnetic resonance imaging.

HIV-Associated Vacuolar Myelopathy and HIV-Associated Dementia as the Initial Manifestation of HIV/AIDS

HIV-associated vacuolar myelopathy (HIV-VM) is the most common cause of spinal disease in HIV/AIDS. HIV-VM causes progressive spastic paraparesis, sensory ataxia, and autonomic dysfunction. It is a progressive myelopathy that shares features with subacute combined degeneration seen in vitamin B12 deficiency as well as other neurological diseases and can occur synchronously with HIV-associated dementia (HAD). Here, we describe a rare case in which a patient’s initial presentation of HIV/AIDS was both HIV-VM and HAD. A fifty-three-year-old man presented with a six-month history of numerous falls due to progressive gait instability with associated memory loss, tremor, urinary retention, and impotence. His exam was significant for hyperreflexia and weakness in bilateral lower extremities, upgoing plantar reflex, dysmetria, and ataxic gait. MRI-brain was notable for nonspecific volume loss and diffusely increased T2 signal throughout the supratentorial white matter. Lumbar puncture showed isolated lymphocytic pleocytosis with all other CSF testing unremarkable. He ultimately tested positive for HIV-1, with a CD4 count of 157 cells/mm3 and a viral load of 874,000 copies/mL. He was diagnosed with HIV-VM and HAD which improved after several months of antiretroviral therapy. This case highlights the importance of considering HIV testing in a patient with a sensory neuropathy and/or progressive cognitive impairment.

HIV-Associated Vacuolar Encephalomyelopathy

We report a case of HIV-associated vacuolar encephalomyelopathy with progressive central nervous system dysfunction and corresponding vacuolar degeneration of the spinal cord, cranial nerves, and brain, the anatomic extent of which has not previously been described. Vacuolar myelopathy classically presents as a spinal syndrome with progressive, painless gait disturbance in the setting of advanced HIV and AIDS. Vacuolar involvement of the brain and cranial nerves, as illustrated in this case report, is a newly described variant of this condition that we term vacuolar encephalomyelopathy.
