Morning Glory Disc Anomaly

AbstractSeveral extraorbital findings have been described in morning glory disc anomaly (MGDA), including optic pathway abnormalities. We want to emphasize the importance of looking for ipsilateral optic nerve and chiasm thickening in MGDA-affected patients because we think that it may be a relevant common associated finding to date not stressed by anyone. We report three cases of clinically diagnosed unilateral MGDA in which magnetic resonance imaging revealed enlargement of the ipsilateral optic nerve and chiasm. A literature analysis was made and previously reported MGDA cases, and case series were checked, looking for described, or misunderstood similar magnetic resonance imaging findings. Three other cases with very similar prechiasmatic optic nerve and chiasm findings were identified from the literature. Two further cases are discussed as possibly characterized by similar misinterpreted magnetic resonance features. Our study broadens the constellation of intra- and extraorbital findings of MGDA. Though magnetic resonance imaging is not sufficient to determine the neuropathological substrate of this finding, clinicians and radiologists should be aware of the possible association of MGDA with ipsilateral thickening of the optic nerve and chiasm, to properly plan the clinical and imaging follow-up.

Background Vascular compression of the anterior optic pathway has been documented as an infrequent cause of visual impairments. Here we characterize such vascular compression using magnetic resonance imaging. Methods A total of 183 patients without pathologies affecting the optic pathways underwent T2-weighted or constructive interference steady-state sequence magnetic resonance imaging. Imaging data from coronal sections were analyzed. Results A vascular compression of the anterior optic pathway was identified in 20 patients (11%). They comprised 13 men and 7 women with a mean age of 60.8 years. The vascular compressions were observed at 22 sites, 15 on the optic nerve (ON) and 7 on the optic chiasm (OC). Twelve of them were on the right and 10 were on the left side. The offending vessels were the supraclinoid portion of the internal carotid artery in 86.4% and the A1 segment of the anterior cerebral artery in 13.6%. Compression sites at the ON and OC were variable, with the inferolateral surface being the most frequent (77.3% occurrences). In 2 patients (9.1%), the ON was compressed in a sandwich manner. Conclusions Vascular compression of the ON and OC may not be an infrequent occurrence in the cranial cavity. Progressive and unexplainable visual impairment might possibly be caused by vascular-compressive neuropathy.

Abstract Morning Glory Anomaly is rare but its fundoscopic findings are well documented in the ophthalmologic literature. It is sporadic, without sexual predisposition and usually unilateral. Furthermore, it is associated with numerous central nervous system anomalies, including vasculopathy of the central nervous system. This case series reports four pediatric patients over a three year period in which ophthalmologic evaluation identified Morning Glory Anomaly. Magnetic Resonance Imaging (MRI) and Magnetic Resonance Angiography (MRA) were subsequently obtained to assess for associated intracranial vascular anomalies. This report is of significance as it demonstrates the spectrum of intracranial vasculopathy in this rare entity.

Basal Encephalocele

The basal encephaloceles refer to rare entities and they correspond to herniation of brain tissue through defects of skull along the cribiform plate or the sphenoid bone. A rare morning glory syndrome, with characteristic retinal defect has been reported in association with basal encephaloceles. Hypophysis hormonal deficiencies may occur. We accounted for a pituitary dwarfism with delayed diagnosed transsphenoidal encephalocele associated with morning glory syndrome, showing the alterations found in retinography, computed tomography and magnetic resonance imaging.
