Optic nerve hypoplasia (ONH) is one of the most common causes of congenital visual impairment. It was first described in 1915 and represents a developmental disorder of the central nervous system. It is often associated with intracranial midline defects and is then referred to as septo-optic dysplasia (SOD). The symptoms of ONH range from minimal visual dysfunction to significant visual impairment with sensory defect nystagmus and even blindness. The ONH is often associated with further systemic, endocrinological and neurological abnormalities requiring a close interdisciplinary treatment of the patients...

Posterior pituitary ectopia has been reported previously in association with optic nerve hypoplasia, as a variant of septo-optic dysplasia. We describe a 14-year-old boy with posterior pituitary ectopia and bilateral optic disc pits. He had hypopituitarism and a reduction in visual acuity to 20/40 in each eye, owing to loss of foveal ganglion cells. Optic pits and posterior pituitary ectopia may have occurred together in the same subject by chance, but the rarity of both conditions suggests a possible association...

We retrospectively reviewed the clinical and radiologic characteristics of 17 individuals with septo-optic dysplasia (SOD) and attempted to identify correlations between imaging findings, clinical features, and neurodevelopmental outcome. Surprisingly, only 1 (6%) individual was classified as classic SOD (with septum pellucidum/corpus callosum dysgenesis), 3 (18%) as SOD-like (with normal septum pellucidum/corpus callosum) and the majority, 13 (76%), as SOD-plus (with cortical brain malformation). Cortical abnormalities included schizencephaly, polymicrogyria, and gray matter heterotopias...

A clinical diagnosis of septo-optic dysplasia (SOD) is made when two or more of the classical triad of optic nerve hypoplasia, pituitary hormone abnormalities or midline brain defects. To date, a clinical study of SOD, regarding its endocrinological features in particular, has not been undertaken in Japan. We retrospectively evaluated 14 SOD patients at our institution. Hormonal dysfunction was present in 78% of cases: ten cases presented combined hypopituitarism and one case presented precocious puberty. GHD and hypothyroidism were the most common endocrinopathies...

RATIONALE: Septo-optic dysplasia (SOD) is a rare congenital disorder that may cause jaundice in infants. However, it is usually prone to neglect and misdiagnosis in infants with cholestasis because endocrine disorder such as panhypopituitarism is rare in the cause of infantile cholestasis. We report a case of SOD concurrent with acquired cytomegalovirus (CMV) infection, who presented with prolonged jaundice as the first clinical sign. PATIENT CONCERNS: The patient was a 2-month-old male infant who presented with cholestasis, combined with fever and panhypopituitarism...

Septo-optic dysplasia (SOD) is a rare condition for which the precise etiology is still unclear. Elucidating the genetic component of SOD is a difficult but necessary task for the future. We describe herein a novel HESX1 c.475C>T (p.R159W) mutation and demonstrate its potential pathogenicity in the development of this rare disease.

Septo-optic dysplasia (SOD)/de Morsier's syndrome is characterized by optic nerve hypoplasia, pituitary endocrine dysfunction, and midline brain abnormalities. Hypopituitarism, hypothyroidism, hypogonadism, and adrenal insufficiency can lead to severe hypoglycemia, adrenal crisis, seizures, and sudden death. Anesthetic management of SOD was associated with high perioperative mortality. A 9-year-old male child proposed for dental treatments/extractions. Medical history of SOD with hypopituitarism, hypothyroidism, and delayed psychomotor development was observed...

Research over the last 20 years has led to the elucidation of the genetic aetiologies of Isolated Growth Hormone Deficiency (IGHD) and Combined Pituitary Hormone Deficiency (CPHD). The pituitary plays a central role in growth regulation, coordinating the multitude of central and peripheral signals to maintain the body's internal balance. Naturally occurring mutation in humans and in mice have demonstrated a role for several factors in the aetiology of IGHD/CPHD. Mutations in the GH1 and GHRHR genes shed light on the phenotype and pathogenesis of IGHD whereas mutations in transcription factors such as HESX1, PROP1, POU1F1, LHX3, LHX4, GLI2 and SOX3 contributed to the understanding of CPHD...

Septo-optic dysplasia (SOD) is a congenital disorder characterized by optic nerve, pituitary and midline brain malformations. The clinical presentation of SOD is highly variable with a poorly understood etiology. The majority of SOD cases are sporadic, but in rare instances inherited mutations have been identified in a small number of transcription factors, some of which regulate the expression of Sonic hedgehog (Shh) during mouse forebrain development. SOD is also associated with young maternal age, suggesting that environmental factors, including alcohol consumption at early stages of pregnancy, might increase the risk of developing this condition...

INTRODUCTION: Mutations in the transcription factor HESX1 can cause isolated growth hormone deficiency (IGHD) or combined pituitary hormone deficiency (CPHD) with or without septo-optic dysplasia (SOD). So far there is no clear genotype-phenotype correlation. PATIENTS AND RESULTS: We report four different recessive loss-of-function mutations in three unrelated families with CPHD and no midline defects or SOD. A homozygous p.R160C mutation was found by Sanger sequencing in two siblings from a consanguineous family...

Introduction Gastroschisis is considered to be an isolated abdominal wall defect that is infrequently associated with other anomalies. Case This case describes an infant with gastroschisis who developed refractory shock after an uncomplicated surgery for bowel atresia. He was found to have adrenal insufficiency secondary to septo-optic dysplasia with panhypopituitarism. Conclusion Gastroschisis and septo-optic dysplasia arise from vascular disruptions, therefore presence in the same infant can be more than just a coincidence...

Introduction We describe a newborn female infant with septo-optic dysplasia (SOD) presenting with bilateral dilated and fixed pupils. Conclusion Our report is unique because the incidental finding of bilateral dilated and fixed pupils on the newborn exam was the only clinical finding which led to a prompt work-up and eventual diagnosis of SOD.

BACKGROUND: Central diabetes insipidus (CDI) results from a number of conditions affecting the hypothalamic-neurohypophyseal system to cause vasopressin deficiency. Diagnosis of CDI is challenging, and clinical data and guidelines for management are lacking. We aim to characterize clinical and radiological characteristics of a cohort of pediatric patients with CDI. METHODS: A chart review of 35 patients with CDI followed at North Carolina Children's Hospital from 2000 to 2015 was undertaken...

Septo-optic dysplasia (SOD) is a rare congenital heterogeneous malformation. SOD was formerly known as de Morsier syndrome, which associated a midline brain defect such as an absent septum pellucidum with optic nerve hypoplasia. The diagnosis of SOD is made when there are two or more characteristics of the classic triad. The triad consists of optic nerve hypoplasia, pituitary hormone abnormalities, and midline brain defects, although it can vary in the severity of clinical presentation and phenotype. The purpose of this article is to review a case and analyze the literature regarding prevalence, etiology, clinical presentation, diagnosis, and management of SOD...

Heterozygous and/or homozygous HESX1 mutations have been reported to cause isolated growth hormone deficiency (IGHD) or combined pituitary hormone deficiency (CPHD), in association with septo optic dysplasia (SOD). We report a novel heterozygous HESX1 mutation in a CPHD patient without SOD phenotypes. The propositus was a one-year-old Japanese girl. Shortly after birth, she was found to be hypoglycemic. She was diagnosed with central adrenal insufficiency based on low cortisol and ACTH at a time of severe hypoglycemia...

CONTEXT: Neonatal central diabetes insipidus (CDI) with or without adipsia is a very rare complication of various complex hypothalamic disorders. It is associated with greater morbidity and a high risk of developing both hypernatremia and hyponatremia, due to the condition itself or secondary to treatment with vasopressin analogs or fluid administration. Its outcomes have yet to be evaluated. OBJECTIVE: To investigate the clinical outcomes of patients with neonatal-onset CDI or adipsic CDI with hypernatremia...
