Giant cell tumors are rare, benign but aggressive and locally invasive tumors that usually affect the long bones in the limbs, typically presenting during the 3rd or 4th decade of life. Giant cell tumors of the skull are exceedingly rare, and less than 150 cases have been reported to date, of which less than 10 were described in the pediatric population. Here, we present the case of a 14 year old female that progressively developed severe headaches, blurr...

With congenital hypopituitarism, the clinical manifestations of pituitary hormone deficiencies usually appear during infancy or early childhood. Typically, one or more anterior pituitary hormones are deficient, and the most severe manifestations include neonatal hypoglycemia, electrolyte imbalances and failure to thrive. We present the case of a 43 year old male, with cardiovascular and metabolic comorbidities (arterial hypertension, type 2 diabetes mellitus), with no prior ho...

Pineal germinomas account for the majority of intracranial germ cell tumors. Surgery and radiation are usual management options, and secondary hypopituitarism can ensue after both. Diabetes insipidus is particularly common after surgical removal of pineal tumors, but improvement in polyuria and polydipsia years after surgery is exceedingly rare. Here, we present the case of a 49-year-old male, who was diagnosed with a pineal germinoma at the age of 20, which was surgically rem...
