Hydatid cyst, spinal cord

Spinal hydatid disease is rare even in countries where echinococcosis is endemic. A survey from Turkey reviews 28 reports of spinal hydatid diseases during the past 5 decades (ref. 3). Most cases however presented with intraspinal extradural hydatid cysts associated with vertebral involvement. Radiological presentation is non specific and most of the patients were misdiagnosed preoperatively as Pott's disease. In this review however no case of an intramedullary lesion is mentioned.  

 

Image 1: Sagittal T1WI: a cystic hypointense lesion is shown within the conus.

Image 2: Sagittal T2WI: a homogeneous hyperintense cyst is found with regular margins.

Image 3: Coronal Gd T1WI and image 4: Axial Gd T1WI: there is a mild enhancement at both ends of the cyst.
