Hamartoma MRI
Introduction
Overview
Overview
MRI is the modality of choice for assessment of hypothalamic, spleen, kidney, and other abdominal hamartomas. On MRI, hamartoma is characterized by a heterogeneous signal in T1 and high signal due to fat and cartilaginous components in T2.

MRI
MRI may be helpful in the diagnosis of hamartomas. Findings on MRI suggestive of hamartomas include:[1][2][3]
- T1: isointense to cerebral cortex
- T1 contrast: no contrast enhancement
- T2: iso to hyperintense to cerebral cortex, the higher the proportion of glial cells, the higher the T2 signal.
- MR spectroscopy
