Conclusion

Hypothalamic hamartomas are an important cause of precocious puberty and epilepsy in young patients. When small in size, these lesions can be subtle and easily overlooked due to their similarity to normal brain tissue. When large, a cerebriform or 'brain-within-a-brain' appearance helps to clinch the diagnosis of a hypothalamic hamartoma and distinguish this lesion from other pediatric suprasellar masses.
