摘　　要：Background Cavernous malformations of the spinal cord are a rare type of vascular malformation,comprising approximately 5 to 16%of all vascular lesions in the spinal cord.Depending on their origin position,these malformations can be distributed in different locations within the spinal canal.Although intramedullary cavernous malformations have been reported in the literature,they are exceedingly rare.Furthermore,highly calcified or ossified intramedullary cavernous spinal malformations are even rarer.Case presentation Here,we present a case report of a 28-year-old woman diagnosed with a thoracic intramedullary cavernous malformation.The patient had been experiencing progressive numbness in her distal limbs for a period of 2 months.During routine lung computed tomography screening for COVID-19,a hyperdense mass was noted in the patient’s spinal canal.Magnetic resonance imaging revealed a mulberry-shaped intramedullary mass at the T1-2 level.The patient underwent surgical treatment,during which the entire lesion was successfully removed,resulting in a gradual improvement of her symptoms.Histological examination confirmed the presence of cavernous malformations with calcification.Conclusions Intramedullary cavernous malformations with calcification are rare and special type that should be treated surgically in the early stage without significant neurological impairment before rebleeding or enlargement of the lesion can occur.
