• Normal Hearing

  The parents have normal hearing, and brain magnetic resonance imaging showed no abnormalities. They are nonconsanguineous but from the same small village. [ncbi.nlm.nih.gov]

• Suggestibility

  The coexistence of these multiple physical and brain abnormalities in a brother and sister suggests a new autosomal recessive syndrome with a slowly progressive course. [ncbi.nlm.nih.gov]

  Here, the coexistence of these multiple unusual features and brain abnormalities in siblings suggests a syndrome, more extensive than previously described, with a slowly progressive course. [nature.com]

• Frontal Bossing

  We describe a brother and sister with severe developmental delay, hypotonia, partial agenesis of the corpus callosum, pontine hypoplasia, focal white matter degenerative abnormalities, macrocrania, frontal bossing, deep-set eyes, and hypertelorism. [ncbi.nlm.nih.gov]

• Headache

  We report the case of an 18-years old young patient with no history who was admitted to the emergency department for generalized seizures and atypical headache, the onset of symptoms dated back to two months, neurological examination was normal. [semanticscholar.org]

  Mild cases tend to involve headaches, seizures and speech problems which don\'t appear for years. [checkorphan.org]

  In mild cases, symptoms (such as seizures, repetitive speech, and/or headaches) may not appear for years. [medicinenet.com]

  In mild cases, symptoms such as seizures, repetitive speech, or headaches may not appear for years. [brainfoundation.org.au]

  Older patients are usually diagnosed during tests for symptoms such as seizures, monotonous or repetitive speech, or headaches. In mild cases it may be overlooked due to lack of obvious symptoms during childhood. [rarediseases.org]

Is there any treatment? There is no standard course of treatment for ACC. Treatment usually involves management of symptoms and seizures if they occur. [my.clevelandclinic.org]

Treatments for Agenesis of the Corpus Callosum Currently, there are no treatments to restore the corpus callosum to normal. The main course of treatment for agenesis of the corpus callosum is to manage any complications that may arise. [childrensnational.org]

Treatment There is no standard course of treatment for ACC. Treatment usually involves management of symptoms such as hydrocephalus and seizures if they occur. Prognosis ACC does not cause death in the majority of patients. [brainfoundation.org.au]

Prognosis - Partial agenesis of corpus callosum Prognosis varies depending on the type of callosal abnormality and associated conditions or syndromes. [checkorphan.org]

MR findings avoid misdiagnosis with a medial interhemispheric cyst associated to corpus callosum agenesis in which the prognosis is unpredictable. [unboundmedicine.com]

What is the prognosis? Prognosis depends on the extent and severity of malformations. Intellectual impairment does not worsen. [my.clevelandclinic.org]

Treatment and prognosis The overall prognosis can be highly variable depending on the presence of other associated anomalies. High-quality MRI essentially eliminates differentials due to the exquisite imaging of the corpus callosum. [radiopaedia.org]

Prognosis Prognosis depends on the extent and severity of malformations. [ 11 ] It is not possible for the corpus callosum to regenerate or degenerate. [patient.info]
