Presentation
The fronto-temporo-parietal opercula present an abnormally open appearance, which is frequently associated with an overlying large anomalous venous structure. [moh-it.pure.elsevier.com]
Conclusion: As one of the most common types of developmental cortical malformations, polymicrogyria can be seen in patients who are presented with clinical findings, such as epilepsy, mental motor retardation and spasticity and polymicrogyria may present [scopemed.org]
The most common clinical presentation is intractable seizures. Heterotopia present as nodular foci of grey matter intensity on all sequences. They do not enhance. Heterotopia Images of a typical subependymal heterotopia. [radiologyassistant.nl]

Course
- Severe Clinical Course
Not surprisingly, patients with more extensive cortical involvement seemed to have the most severe clinical course. [ajnr.org]
Eyes
- Retinal Pigmentation
There was diffuse retinal pigment epithelium (RPE) atrophy with tessellated background, arteriolar attenuation, and choroidal sclerosis in both the eyes [Figure 1] g. There were no RPE clumps or bony spicules. [annalsofian.org]

The syndrome is manifested by global developmental delay of at least moderate severity, epilepsy, dysconjugate gaze, and bilateral pyramidal and cerebellar signs. Polymicrogyria can be generalized or focal, unilateral or bilateral. [cags.org.ae]
Few patients are candidates for surgery. [11] The global developmental delay that affects 94% can also be mitigated in some patients with occupational, physical, and speech therapies. [en.wikipedia.org]
- Truncal Ataxia
All three had esotropia, increased muscle tone, mild truncal ataxia, and finger dysmetria, without dysmorphic features or other congenital anomalies. They also had strabismus. [cags.org.ae]
