Summary:

Description
  • Radiopaedia case ID: 16374
  • Image ID: 1637051
  • Plane projection: Sagittal
  • Aux modality: T2
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Beautiful demonstration of septum pellucidum perforation, with dilatation of the 3rd and lateral ventricles and a focal septum in the aqueduct causing obstruction, as evidenced by a lack of flow void. The ballooned 3rd ventricle erodes the dorsum sellae causing marked deformity of the hypothalamus, pituitary stalk, and pituitary gland. The sagittal series demonstrate typical Chiari I malformation without syringomyelia. Note the dysplastic (pyramidal shaped) cerebellar tonsils protruding through the foramen magnum.
