In this case, the radiological evidence of a mass in the tuber cinereum was classic for hypothalamic hamartoma. They are more common in males.
Symptoms are rare.
Sometimes these lesions are brought to attention by abnormalities of endocrine function which often appear in childhood, but can appear in adults. These lesions are fairly well-defined masses attached to the floor of the third ventricle or associated with the tuber cinereum. They are typically about 1-2 cm in diameter, but some may be very large and protrude into the third ventricle. Typically there is no calcification or cystic component, which can help distinguish them from a ganglioglioma radiographically. Microscopically, the tissue resembles cerebral gray matter with a jumbled, disordered appearance to the neurons.
