Septo-Optic Dysplasia (De Morsier Syndrome) - Ultrasoun

Septo-optic dysplasia is a disorder in early brain development. Characteristics of the condition include: Under-development of the optic nerves. These nerves carry visual information from the eyes to the brain The Authors. Ultrasound in Obstetrics & Gynecology published by John Wiley & Sons Ltd on behalf of the International Society of Ultrasound in Obstetrics and Gynecology. INTRODUCTION Septo-optic dysplasia (SOD), also known as De Morsier syndrome, is a rare congenital disorder, affecting 1 in 10000 live births1,2. The condition is defined as th Septo-optic dysplasia is a rare congenital anomaly and has a reported prevalence of 6.3 per 100,000. It has a near equal distribution among males and females,¹ and it is typically diagnosed in newborns and infants. While absence of the septum pellucidum is not associated with specific cognitive or developmental abnormalities, visual loss and. Septo-optic dysplasia can be suspected in utero and can appear isolated but has substantial associated central nervous system anomalies identified on fetal MRI or after birth. Partial absence of the CSP can be a prenatal sign of suspected SOD, although fetal MRI lacked the spatial resolution to identify it accurately in all cases

Septo-optic dysplasia is a disorder of early brain development. Although its signs and symptoms vary, this condition is traditionally defined by three characteristic features: underdevelopment (hypoplasia) of the optic nerves, abnormal formation of structures along the midline of the brain, and pituitary hypoplasia What is septo-optic dysplasia? Septo-optic dysplasia is a condition of brain development. The condition is called septo-optic dysplasia because of underdevelopment of the optic nerves and problems with a part of the brain called the septum. The underdevelopment of the optic nerves is called optic nerve hypoplasia Septo-optic dysplasia is a congenital condition, that is, it is present at birth, although it may not be diagnosed until childhood, or rarely, adolescence. Septo-optic dysplasia was previously prenatal ultrasound scanning, but it is most commonly diagnosed during childhood. It i Septo‐optic dysplasia (SOD) is a clinical syndrome characterized by varying combinations of optic nerve hypoplasia, pituitary gland hypoplasia and abnormal cavum septi pellucidi. It is suspected on prenatal imaging when there is non‐visualization or hypoplasia of the septal leaflets

Septo-optic dysplasia is the diagnosis when optic nerve hypoplasia is seen in conjunction with dysgenesis of the septum pellucidum. Nearly two-thirds of these patients have hypothalamic-pituitary dysfunction, and half have schizencephaly. The disorder is difficult to classify because of the diversity of clinical and pathologic manifestations Septo-optic dysplasia (SOD), known also as de Morsier syndrome, is a rare congenital malformation syndrome that features a combination of the underdevelopment of the optic nerve, pituitary gland dysfunction, and absence of the septum pellucidum (a midline part of the brain) Septo-optic dysplasia (De Morsier syndrome) is a heterogeneous condition defined by a combination of optic nerve hypoplasia, midline neurological malformations (such as agenesis of the corpus collosum and absence of the septum pellucidum), and pituitary-hypothalamic dysfunction (Polizzi et al., 2006 )

Septo-optic dysplasia (SOD) is a rare malformation which classically includes optic nerve hypoplasia, midline brain defects (most commonly absent or cavum septum pellucidum or agenesis of the corpus callosum), and hypopituitarism, sometimes with hypoplasia of the anterior pituitary and/or ectopic posterior pituitary
  4. Although relatively rare, septo-optic-pituitary dysplasia complex is a highly relevant topic for pediatric neurologists, ophthalmologists, and pediatricians as the identification of visual impairment due to optic nerve hypoplasia requires the physician to consider the possibility of congenital hypopituitarism, a disorder that may be life-threatening if undetected and untreated

Ultrasound diagnosis: Unilateral or bilateral cleft between the ventricular system and the subarachnoid space. In about 70% of cases the lesion is in the parietal lobe. In 50-90% of cases there are other associated brain abnormalities, including agenesis of the cavum septum pellucidum, septo-optic dysplasia and severe ventriculomegaly Although not constituting formal proof, if maternal estradiol levels are normal (Lepinard et al. 2005), if the posterior branches of the optic chiasma are normal in size by 3D ultrasound (Fig. 7.35a) (Bault 2006, 2007; Bault et al. 2011), and if the olfactory bulbs can be visualized (Fig. 7.35b), this would tend to rule out septo-optic dysplasia Disorders of prosencephalic midline development, agenesis of the corpus callosum, agenesis of septum pellucidum, and septo-optic dysplasia, usually have less severe presentations, but affected subjects may suffer from neurodevelopmental retardation and endocrinologic and visual disorders. + Lepinard C, Coutant R, Boussion F, Loisel D, Delorme B, Biquard F, Bonneau D, Guichet A, Descamps P.

Septo-optic dysplasia (SOD), also known as de-Morsier syndrome, is a rare disorder characterized by any combination of optic nerve hypoplasia, pituitary gland hypoplasia, and midline abnormalities of the brain including absence of the septum pellucidum and corpus callosum dysgenesis. The variable presentation of SOD includes visual, neurologic, and/or hypothalamic-pituitary endocrine defects Instead, absence of the septum pellucidum is associated with other conditions such as septo-optic dysplasia. Treatment options for the condition vary depending on the underlying disorder. Diagnosis of absence of the septum pellucidum can be made through imaging such as an MRI Optic nerve hypoplasia is the unifying feature of a spectrum condition, commonly known as septo-optic dysplasia (SOD) or DeMorsier syndrome, which includes hypopituitarism and absence of the septum pellucidum on MRI scan The data in this article are based on investigations performed in 25 children with suspected septo-optic dysplasia (SOD). There are many signs and methods that help in the diagnosis of SOD. In particular, the ocular fundus, abnormalities of the hypothalamo-pituitary axis and other midline brain structures should be described. In order to achieve a more holistic and functional diagnosis, the. Septo-optic dysplasia is generally sporadic, meaning the situation typically happens in individuals with no history from the disorder within their family.

Septo-optic dysplasia (SOD), also known as de Morsier syndrome, is a condition characterized by optic nerve hypoplasia and absence of the septum pellucidum and, in two-thirds of patients hypothalamic-pituitary dysfunction. It is best thought of as being part of the holoprosencephaly spectrum (see classification system for midline malformations).. (Ultrasound Review) The cavum septum pellucidum (CSP) is a cerebral cavity commonly demonstrated on ultrasound examinations performed during the second and third trimesters. Absence of the CSP is characteristic of brain abnormalities, such as agenesis of the corpus callosum, holoprosencephaly, septo-optic dysplasia, and schizencephaly In our two cases, septo-optic dysplasia was not considered as a prenatal differential diagnosis because we could not diagnose the absence of the septum pellucidum at prenatal ultrasound. Low maternal estriol in pregnancy is known to be associated with fetal hypopituitarism with ACTH deficiency ( 10 ), but we did not check maternal serum and. Summary.

Septo-optic dysplasia is a disorder of early brain development. In affected individuals, the optic nerves are abnormally small and make fewer connections than usual between the eyes and the brain. As a result, people with optic nerve hypoplasia have impaired vision in one or both eyes Children who are born without this membrane and also have other abnormalities--pituitary deficiencies and abnormal development of the optic disk--have a disorder known as septo-optic dysplasia.
