Abstract
Introduction: Stroke and lower extremity venous thromboemboli have been commonly reported following acute infection with severe acute respiratory syndrome of coronavirus-19 (SARS-CoV-2), but spinal cord infarction or ischemia is far less frequent. When diagnosis of either COVID-19 or its neurovascular complications are delayed, functional outcomes may be compromised.
Case presentations: We present 2 middle-aged, Caucasian females with sudden onset of non-traumatic spinal cord injury (NTSCI) due to spinal cord infarction or ischemia attributed to acute infection with SARS-CoV-2. Both demonstrated lower extremity weakness with absent pinprick, but eventually recovered limited ambulation with equipment and bracing. Their reports of myalgias, neuropathic pain, muscle spasticity, and urinary tract complications, including hematuria and infections, exceeded the frequency and severity of other SCI individuals of similar age and degree of neurological impairment. One individual experienced a delay in diagnosis of COVID-19 and the other, a delay in identifying the spinal cord infarction. Both had protracted rehabilitation courses and have since developed post-acute sequelae of SARS-CoV-2 (PASC).
Discussion: Vascular injuries in the form of spinal cord infarction can occur due to SARS-CoV-2, with resultant moderate to severe sensory and motor impairment and long-term disability. Symptoms such as myalgias, neuropathic pain, muscle spasms, and frequent bacterial infections are a part of PASC, independent of any spinal cord injury. The dual presence of PASC and recent SCI attributed to COVID-19 may lead to increased severity of symptoms shared by both conditions, only heightening the need for early rehabilitation.
