CT Scan and MRI study

🟢 1. Normal Anatomy (Top-Left Panel)🧠 Anatomy Outlined: Shows a fully formed, healthy corpus callosum and surrounding structures with specific labels:

Genu, Truncus, Isthmus, Splenium, and Rostrum (the different segments of the corpus callosum).

Anterior commissure, Septum pellucidum, Fornix, and Thalamus / Thalamic adhesion.An arrow points out a "Normal isthmal notch"
🟤 2. Complete Callosal Agenesis (Top-Right Panel)🚫 Phenomenon: The corpus callosum is completely missing.🔬 Key Features: The scan shows an empty space where the bundle of nerves should be, along with a label pointing to a "Tiny anterior commissure?".

🟠 3. Partial Callosal Agenesis (Second Row Panels)

📐 Left Scan ("Some truncus"): Shows a partially formed structure labeled with "Some truncus" and "Splenium", an "Anterior commissure", and a "Commissural plate remnant".

📐 Right Scan ("Hypertrophic"): Points out an "Anterior commissure" and a "Commissural plate remnant" leading up to a "'Hypertrophic' hippocampal commissure (≈ rudimentary splenium)".

🟢 4. Hippocampal Commissure Agenesis vs. Blunt Splenium (Third Row Panels)

📉 Hippocampal commissure agenesis (Left Scan): Features "Low hanging fornices" and notes "No hippocampal commissure $\rightarrow$ no development of splenium" within a circled area.

📉 Callosal hypoplasia, "blunt" splenium (Right Scan): Shows "Normal position fornices" and a circled area noting "Hippocampal commissure present, blunt splenium".

🟡 5. Callosal Hypoplasia & Dysplasia (Bottom Row Panels)

📉 Callosal hypoplasia (minor dysplasia) [Left Scan]: The corpus callosum is formed but thinner than usual. The text notes: "All components present, minor morphological irregularities".

📉 Callosal hypoplasia with dysplasia (Right Scan): The structure is both underdeveloped and malformed. The text notes: "Small corpus callosum, abnormal morphology".
