MON-077 A Case of Growth Hormone Deficiency in Sturge-Weber Syndrome

Introduction: Sturge-Weber syndrome (SWS) is a congenital neurocutaneous disorder characterized by a port wine stain on the skin in the distribution of the ophthalmic branch of the trigeminal nerve (vascular malformation of skin), glaucoma, and leptomeningeal angiomas. Central nervous system abnormalities may increase the risk of hypothalamic-pituitary dysfunction. One previous study showed that SWS patients had higher prevalence of growth hormone deficiency than the general population although the etiology is unclear. This case report describes a patient who was initially diagnosed with SWS and later confirmed with complete growth hormone deficiency. Case: A 7-year-and-11-month-old boy who had been diagnosed with SWS visited a tertiary center for the evaluation of short stature [111.1cm (<3 percentile)]. He was born at 37 weeks of gestational age with birth weight of 3230g by cesarean section and had a port wine nevus on the right side of the face since birth. He had a history of epilepsy first occurring at 6 months of age when he was diagnosed with SWS. There were two more attacks of seizure till 32 months of age. Brain magnetic resonance imaging revealed leptomeningeal angioma, choroidal hemangioma, and diffuse brain atrophy. He was diagnosed with glaucoma and had been managed with surgery and medication. There was no family history of SWS or any other brain anomaly. His mid-parental height was 167.7cm. All blood tests were normal including complete blood count, chemistry, and thyroid function test. Hand x-ray showed delayed bone age. Cocktail test was performed for the evaluation of short stature. As a result, he was diagnosed with complete growth hormone deficiency (peak GH on L-dopa test: 2.46 ng/mL, peak GH on glucagon test: 3.71 ng/mL). The recombinant growth hormone therapy was started at the age of 8 years and 1 month. He showed good response to GH treatment. His height became 125.8cm at the age of 9 years and 5 months (height velocity 9.2 cm/year), and 134.3cm at the age of 10 years and 6 months. Conclusion: We experienced a case with Sturge-Weber syndrome and complete growth hormone deficiency which was successfully managed by recombinant growth hormone therapy. It may be better to consider the possibility of GH deficiency even if there are certain conditions that affect the growth itself.
