Abstract :Arachnoid webs are intradural, extramedullary, fibrous connective tissue bands located, originating from the pial surfaces within the subarachnoid space. Patients may present asymptomatically or with symptomatic conditions associated with cord compression and disturbances in cerebrospinal fluid flow dynamics. Although arachnoid webs themselves are often indistinguishable via imaging modalities, the presence of the highly specific yet non-pathognomonic “scalpel sign” is crucial for diagnosing this entity. Magnetic resonance imaging is the most useful modality for diagnosis. This case report presents the clinical and radiological findings of a 39-year-old patient diagnosed with the rare entity of thoracic arachnoid web.
