Abstract

Pelvic masses, especially hydatid disease, rarely present with sciatica (1, 2). We present the computed tomography (CT) and the magnetic resonance imaging (MRI) findings of a 49-year-old female patient with presacral hydatid disease, who was evaluated for her sciatica. We also want to emphasize the importance of assessing the pelvis of patients with symptoms and clinical findings that are inconsistent and that cannot be satisfactorily explained by the spinal imaging findings.

Figure

• 

  Fig. 1 T2 weighted, right parasagittal MRI of the lumbar spine reveals a multiloculated cystic mass in the presacral area (arrowheads).

• 

  Fig. 2 A contrast enhanced CT scan of the pelvis in the axial plane showing the right-sided multiloculated cystic mass (arrowheads) in the presacral area in the close vicinity of the sacral foramen.

  Fig. 3 A. An axial T1 weighted MRI of the pelvis showing the right-sided cyst (C) in the close vicinity of the sacral nerve fibers (arrowhead). Note the other cyst posterior to the rectum (arrow). B. In the oblique coronal T1 weighted image, the displacement and the compression of the lumbosacral nerve trunk (arrowhead) by the cyst (C) can be seen. C. The nerve plexus (arrowhead) compressed by the cyst (C) can be seen in the oblique coronal T2 weighted image.
