A Pediatric Case of Xanthogranuloma in the Suprasellar Region Detected by a Severe Short Stature after 6 Years Growth Failure

Abstract

Here we report a case of a 12-year-old girl who was referred to our department because of marked short stature of more than −5 SD below the median. Although her growth failure began suddenly at 6 years of age, she never had an examination because she had no other symptoms. Brain MRI examination suggested a tumor in the suprasellar region, and endocrine examination revealed combined pituitery hormone deficiency due to the tumor. Before surgery, the supplementation with hydrocortisone and levothyroxine was initiated. The pathological diagnosis of the surgically removed tumor was xanthogranuloma. The pattern of her growth curve showed a growth failure with sudden onset, which is a typical pattern of short stature secondary to pituitary disfunction including growth hormone deficiency associated with brain tumors. This case suggests that growth failure could be the only symptom in pediatric cases with brain tumors. Improved awareness regarding the association of growth failure with brain tumors is needed for earlier diagnosis and treatment. Furthermore, the growth curves should be carefully evaluated in regular health examinations at school.
