Spinal disease in neurologically symptomatic HIV-positive patients

Area of Science:

• Neurology
• Radiology
• Infectious Diseases

Background:

• Spinal symptoms are common in human immunodeficiency virus (HIV)-positive patients.
• Early HIV infection may present with common spinal pathologies like degenerative disease.
• Advanced HIV infection can lead to complex neoplastic and infectious spinal conditions.

Purpose of the Study:

• To review magnetic resonance imaging (MRI) findings in HIV-positive patients with spinal symptoms.
• To highlight the importance of contrast-enhanced MRI in diagnosing spinal pathologies in this population.
• To correlate MRI findings with clinical, laboratory, and pathological data.

Main Methods:

• Review of spinal MRI scans from 23 consecutive HIV-positive patients with acute neurologic complaints.
• Analysis of medical charts, laboratory, pathological, and autopsy data.
• Literature review on spinal manifestations in HIV-positive individuals.

Main Results:

• Early HIV stages showed predominant degenerative spine and disc disease.
• Contrast-enhanced MRI is vital for detecting pathologies missed by non-contrast studies.
• Neoplastic and infectious causes are critical in advanced HIV, requiring contrast-enhanced MRI.
• Normal cerebrospinal fluid findings do not exclude significant spinal pathology.

Conclusions:

• Contrast-enhanced spinal MRI is essential for accurate diagnosis in HIV-positive patients with spinal symptoms.
• Early and advanced stages of HIV infection present distinct spinal imaging findings.
• Brain imaging may be necessary if spinal studies are inconclusive.
