Abstract
BACKGROUND: Spontaneous spinal subarachnoid hemorrhage (SSH) is an infrequent yet critical condition, accounting for less than 1% of all spinal hemorrhages and presenting substantial diagnostic difficulties. It predominantly arises due to factors such as tumors, trauma, arteriovenous malformations (AVM), and certain medications including anticoagulants. The complexity of its presentation necessitates vigilance from healthcare providers to avert irreversible neurological impairments. CASE DESCRIPTION: This study delineates the unusual case of an 82-year-old woman undergoing direct oral anticoagulant (DOAC) therapy who reported sudden, severe chest and back pain, rapidly escalating to lower limb motor and sensory deficits, coupled with urinary and fecal incontinence. An initial cranial computed tomography (CT) indicated a peri-mesencephalic subarachnoid hemorrhage (SAH). Subsequent spinal CT angiography (CTA) and magnetic resonance imaging (MRI) affirmed the diagnosis of a spontaneous SSH, displaying significant cord compression, particularly in the thoracic regions between the T6 and T9 vertebrae. Emergency laminectomy was done to evacuate the subarachnoid hematoma that was causing cord compression. Postoperatively, the patient recovered partial neurological function. CONCLUSIONS: SSH, though rare, embodies a significant diagnostic hurdle and potential for lasting neurological deficits if not identified and treated promptly. Particularly in patients on anticoagulant therapy presenting with acute onset back pain and neurological dysfunction, SSH ought to be a crucial consideration. It is imperative to integrate prompt and advanced neuroimaging techniques and consider spinal angiography as a golden standard for a comprehensive diagnosis. Treatment strategies depend largely on the presence of neurological deficits, emphasizing the necessity of quick identification and emergency intervention in severe cases. This study elucidates the critical role of timely intervention in optimizing recovery outcomes, highlighting the necessity of including anticoagulant-induced spinal hemorrhage in differential diagnoses for patients manifesting signs of acute spinal cord compression.
