This study reviews imaging for Rathke cleft cysts, finding varied appearances on CT and MRI. These imaging features help differentiate Rathke cleft cysts from other sellar/suprasellar lesions.

Area of Science:

  • Neuroradiology
  • Neuroimaging
  • Endocrinology

Background:

  • Rathke cleft cysts are common non-neoplastic cysts of the pituitary region.
  • Accurate diagnosis relies on characteristic imaging findings.

Purpose of the Study:

  • To retrospectively review clinical, computed tomography (CT), and magnetic resonance (MR) imaging findings in patients with Rathke cleft cysts.
  • To correlate imaging features with pathological diagnosis.

Main Methods:

  • Retrospective review of seven patients with pathologically proved Rathke cleft cysts.
  • Analysis of clinical data, CT, and MR imaging findings.

Main Results:

  • Cysts were located in the anterior sella turcica or suprasellar cistern.

  • CT showed homogeneous low-density lesions in four cases and hyperdensity in three.
  • MR imaging revealed variable signal intensities, including cerebrospinal fluid-like intensity and T1 hyperintensity, with signal heterogeneity in some cases.

    • Conclusions:

    • Rathke cleft cysts exhibit diverse imaging characteristics on CT and MR.
    • Understanding these variations is crucial for accurate diagnosis and differentiation from other sellar/suprasellar pathologies.
