Background Neurosarcoidosis is not a common entity from an endocrinology standpoint. Prompt diagnosis is essential in order to determine appropriate treatment and to establish prognosis. Case presentation Our case illustrates the difficulties encountered in making a diagnosis of sarcoidosis in an adolescent who presented with polyuria, polydipsia and hypernatremia. She developed panhypopituitarism and her deficits did not improve after treatment. Conclusion Pediatric endocrinologists diagnose and treat panhypopituitarism associated with many conditions. Neurosarcoidosis should be considered as part of the diagnosis in patients with panhypopituitarism, especially if there is evidence of multi organ disease. Case reports can effectively address the gap in knowledge due to the limited exposure of physicians to this field, especially in children.
