Background: Capillary hemangiomas are benign vascular tumors that rarely occur in the neuraxis. When encountered in the spine, prompt diagnosis and complete resection is crucial. On rare instances, these lesions can acutely hemorrhage, leading to sudden neurological decline. To date, there are only 16 reported cases of intradural capillary hemangiomas in the cauda equina. Case Description: We report a case of an intradural extramedullary cauda equina capillary hemangioma that resulted in back pain and lower extremity motor deficit. Initial magnetic resonance (MR) imaging demonstrated a bilobular intradural L3-4 cauda equina lesion. The lesion was isointense on T1-weighted imaging, mildly hyperintense on T2-weighted images and avidly enhancing after gadolinium administration. Pathology confirmed the diagnosis of capillary hemangioma. Conclusion: Early diagnosis and treatment of this patient resulted in complete resection of the tumor and return of lower extremity motor function. Capillary hemangiomas should be considered in the differential diagnosis of cauda equina lesions. En bloc resection of these lesions is the mainstay of treatment.
