Neurosyphilis Manifesting as a Longitudinally Extensive Transverse Myelitis: A Case Report.

Abstract

Background: Evaluating patients with ascending sensorimotor deficits has a broad differential diagnosis at initial presentation which can be further narrowed upon neurologic examination but may represent a diagnostic and therapeutic dilemma in light of findings raising suspicion for multiple possible etiologies. Data Collection: In this case, a 29-year-old patient presented with ascending bilateral lower extremity sensory loss, paresthesias, and weakness which progressed to the inability to ambulate. Conclusions: This case highlights the diagnostic approach to patients with bilateral lower extremity sensorimotor deficits, discusses the development of a comprehensive differential diagnosis, and further evaluates the most likely etiologies. Furthermore, this case reviews complexities related to clinical reasoning in the setting of diagnostic uncertainty, particularly when the neurologic structures affected portend high risk for severe disability and early treatment may improve outcome.
