“…Another differential includes Foix-Alajouanine Syndrome (FAS), a congestive myelopathy that is hypothesized to occur due to a decrease in arteriovenous pressure gradient and a decrease in cord perfusion as a result of an existing AVF [ 8 ]. In FAS, the MRI pattern usually shows the same pattern of hyperintensity on T2-weighted images and decreased signal enhancement on T1-weighted images [ 9 , 10 ]. Therefore, both FAS and DVT leading to epidural venous plexus engorgement can present as CES.…”

Patient: Female, 42Final Diagnosis: Cauda Equina syndrome due to extensive DVTSymptoms: Back pain • incontinence • swelling legs • weakness of the lower limbsMedication: —Clinical Procedure: —Specialty: NeurologyObjective:Rare diseaseBackground:Epidural venous plexus (EVP) engorgement occurs due to many conditions, so it can be easily misdiagnosed. This becomes problematic when the diagnosis requires prompt treatment for a good outcome, especially when it results in cauda equina syndrome (CES). We report a case of extensive iliocaval thrombosis leading to epidural venous plexus and ascending lumbar vein engorgement as an outcome of deep venous thrombosis (DVT) due to probable adverse effects of oral combined contraceptive pills (OCCP).Case Report:A 42-year-old woman presented to a rural medical facility with bilateral lower-limb swelling and skin darkening for 2 days. She was transferred to a tertiary medical facility where her condition deteriorated to severe CES. A lower-limbs ultrasonography confirmed the presence of extensive DVT extending to the lower segment of the inferior vena cava. Spine magnetic resonance imaging showed abnormal enhancement of the conus medullaris with thick enhanced cauda equina nerve roots, consistent with a possible case of Guillain-Barré syndrome. However, there was engorgement of the EVP extending to the ascending lumbar, azygos, and hemiazygos veins, which was misdiagnosed. The patient was managed immediately with low-molecular-weight heparin and steroids. She died 4 weeks after admission due to hospital-acquired pneumonia and acute respiratory distress syndrome, probably due to the high dose of steroids.Conclusions:Acute CES has a wide differential diagnosis. This report describes an unusual cause of CES and emphasizes the importance of early recognition to avoid misdiagnosis and management delay. Early identification of this clinical entity markedly decreases morbidity and mortality and thus improves the prognosis. Likewise, underlying causing factors such as venous congestion due to OCCP-related DVT should be considered in the diagnosis.
