| Diagnosis | Agenesis of the Corpus Callosum | |
| History | 17 mos old baby girl with developmental delay | |
| Findings | Radiographic findings include complete absence of the corpus callosum and cingulate gyrus. There is dilatation of the third ventricle and it is displaced superiorly. There is colpocephaly of the occipital horns of the lateral ventricles. Subependymal nodules are noted with in the right lateral ventricle that are isointense to gray matter on all sequences. This is suggestive of heterotopic gray matter. | |

| Diagnosis | Agenesis of the Corpus Callosum | |
| History | This 60 year old man presents with a 4 month history of left side numbness, decreased sensation, and pain in the V2/V3 distribution of his face. There is no prior history of any neurologic problem. | |
| Findings | Sagittal T1, axial T2 and proton density-weighted images do not visualize the corpus callosum; and, there is associated colpocephaly. There is absence of the cingulate gyrus and a radial pattern of sulci and gyri along the medial surface of the cerebral hemisphere. Probst bundles are not well demonstrated on these images and would be best seen in the coronal plane. The lateral ventricles demonstrate their classic wide and straight appearance. Of note, there is also a large incidental subarachnoid cyst in the occipital region posterior to the cerebellum. | |
| Differential Dx | Broadly - including the colpocephaly: 1.Corpus Callosum Agenesis/dysgenesis 2.Hydrocephalus 3.Arnold Chiari malformation 4.Dandy Walker malformation | |

| Diagnosis | Agenesis of the corpus callosum | |
| History | 33 week EGA premature infant. | |
| Findings | Midline sagital image demonstrates gyri ending in a lobular configuration to the region where the corpus collosum should be present, a finding referred to as Probst bundles. The axial images demonstrate culpocephaly - dilatation to the posterior lateral ventricles, especially the atrial regions. There is also a more parallel orientation of the lateral ventricles. The third ventricle communicates superiorly with the interhemispheric fissure. | |

| Diagnosis | Agenesis of the corpus callosum | |
| History | 9 year old female with seizures | |
| Findings | Sagittal T1, axial T1 and proton density, and coronal FLAIR MRI images of the head demonstrate diffuse dysgenesis of the cerebral cortex with colpocephaly. Additionally, the corpus callosum is completely or near completely absent. The cingulate gyrus is absent. Sulci and Gyri on the medial surface of the cerebral hemispheres present a characteristic radial configuration. At least one focus of pachygyria is present in the right posterior temporal region, which is a common association. The lateral ventricles appear widely separated and nonconvergent. This feature and the appearance of small, pointed, frontal horns in the setting of colpocephaly are classic. The third ventricle is elevated to occupy the space of the absent corpus callosum. The anterior and posterior commissures are visualized. The posterior fossa structures are developmentally normal. The anterior cerebral arteries are both present. | |

| Diagnosis | Agenesis of the corpus callosum | |
| History | This is a three day old female with multiple congenital anomalies. An ultrasound examination of the brain was performed (Films 1, 2, 3). | |
| Findings | Coronal images of the brain via the anterior fontanelle from anterior to posterior (Films 1 and 2): Film 1, Scan 1: The frontal horns of the lateral ventricles (arrows) are widely separated. There is no evidence of the "hammock"-shaped corpus callosum. The open arrow points to the area where the corpus callosum should be seen in a normal brain. Scan 2: Sharply angled lateral walls of widely separated bodies of lateral ventricles (arrows). The corpus callosum is not seen. Scan 3: Dilatation and superior displacement of third ventricle (3). Elongation of foramena of Monroe (open arrows). Scan 4: Concave medial borders of lateral ventricles (arrows). There is still no evidence of corpus callosum. Film 2: Slightly dilated (right greater than left) dysmorphic-looking occipital horns (arrows in Scan 2). Film 3: Sagittal scans of brain via the anterior fontonelle: Scan 3: Right parasagittal scan showing the right lateral ventricle. The dysmorphic-appearing occipital horn is moderately dilated (arrow). Scan 4: Mid-sagittal scan showing superior and posterior displacement of the dilated third ventricle (3) with no evidence of the corpus callosum as one examines the area superior to the third ventricle. Note the radial arrangement of the medial cerebral sulci (open arrow) that appear as serpiginous-like striations radiating from the dorsal and superior aspect of the third ventricle (m = massa intermedia, C = cerebellum, 4 = fourth ventricle). | |

| Diagnosis | Agenesis of the corpus callosum. Trigonocephaly, secondary to metopic synostosis. | |
| History | Developmental delay (Film 1) | |
| Findings | Multiple axial sections from a noncontrast CT scan (Film 1) through the head are displayed. All images show anterior pointing of the skull. This pointing is a result of metopic suture synostosis and is probably unrelated to the rest of the findings on the scan. These images show a characteristic winglike configuration of the frontal horns. There is continuity of the interhemispheric fissure with the third ventricle anteriorly on the two lower images. The third ventricle extends upward to an abnormally high position between the lateral ventricles. The lateral ventricles have an unusual configuration. They are abnormally dilated posteriorly and are parallel, instead of being medially convex. This combination of findings continuity of the third ventricle with the interhemispheric fissure, characteristic winglike frontal horns, a high riding third ventricle, dilatation of the atria and occipital horns of the lateral ventricles, and parallel lateral ventricles are all classic findings of agenesis of the corpus callosum. | |
