Bottom Line: These cysts are commonly encountered in the posterior fossa surrounding the brain stem structures.We present a case of pathologically proven supratentorial NE cyst that mimicked a hydatid cyst in its clinical presentation and imaging appearance.Including this pathology in the differential diagnosis of supratentorial cystic lesions is important due to the differences in medical and surgical management.

ABSTRACT
Neurenteric (NE) cysts are uncommon congenital cysts of endodermal origin. These cysts are commonly encountered in the posterior fossa surrounding the brain stem structures. We present a case of pathologically proven supratentorial NE cyst that mimicked a hydatid cyst in its clinical presentation and imaging appearance. Including this pathology in the differential diagnosis of supratentorial cystic lesions is important due to the differences in medical and surgical management.

(b) fMRI overly image during left finger tapping task shows activation of the right primary motor cortex (arrows) and the left supplemental motor area along the medial margin of the cyst

Mentions: A 67-year-old Mediterranean male who had episodes of seizures with altered consciousness. He was subsequently placed on keppra and became seizure-free. Magnetic resonance imaging (MRI) of the brain with and without gadolinium revealed a large well-defined left frontal cystic mass measuring 4.8 cm × 4.0 cm × 4.8 cm. The mass displays cerebrospinal fluid (CSF) intensity with low signal on T1-weighted and fluid-attenuated inversion recovery (FLAIR) images [Figure 1] and high signal on T2-weighted (T2W) images [Figure 2]. The lesion contained sausage-shaped debris of high FLAIR signal in its dependent portion with an internal septation. On post contrast imaging, there is no discernible enhancement of the mass or any surrounding capsule. The diffusion tensor imaging (DTI) and diffusion weighted imaging exhibits presence of a high T2 signal wall surrounded by a low signal capsule. On the functional MRI, the left-sided primary motor cortex is seen along the posterior and lateral margin of the left frontal cyst [Figure 3]. The activated supplemental motor area is seen along the medial margin of the cyst. The DTI revealed that the white matter tracks of centrum semiovale are cleaved and displaced rather than infiltrated and destroyed [Figure 4]. The patient also underwent a computed tomography (CT) scan of the thorax and abdomen, as part of the patient's workup for suspected hydatid cyst disease, which revealed a mesenteric cystic lesion.
