B00.82

Clinical Causes: Reactivation of herpes simplex virus type 1 (HSV-1) or type 2 (HSV-2) within the nervous system Viral spread from head or face infections to the spinal cord Immunosuppression, which can increase susceptibility to viral reactivation In rare cases, direct invasion of the spinal cord by the herpes simplex virus during primary infection Underlying neurological conditions or compromised immune system that facilitate viral invasion

Key Symptoms: Sudden onset of weakness or paralysis in limbs Back pain or neck pain localized to the affected spinal region Loss of sensation or numbness below the level of inflammation Difficulty with bladder or bowel control Fever and general malaise in some cases Headache and neck stiffness Sensitivity to light (photophobia) Symptoms may progress rapidly, leading to severe neurological deficits if untreated

Diagnosis Path: Magnetic resonance imaging (MRI) of the spinal cord to identify areas of inflammation Lumbar puncture to analyze cerebrospinal fluid (CSF) for signs of viral infection Polymerase chain reaction (PCR) testing of CSF to detect herpes simplex virus DNA Serological tests to identify HSV antibodies indicating recent or past infection Biopsy of spinal tissue in rare cases if diagnosis remains uncertain

Treatment Protocols: Antiviral medications such as acyclovir or valacyclovir to inhibit viral replication Corticosteroids to reduce inflammation and manage swelling in the spinal cord Supportive care, including physical therapy to aid in recovery of motor functions Pain management strategies for discomfort Monitoring and management of bladder and bowel functions Rehabilitation services tailored to individual needs
