A 12 year old boy presented with complaints of progressive head ache and visual disturbance which is not improved by any medical approaches. During evaluation CT scan of the head shows supracellar enlargement with calcification is seen. The diagnosis is?

**Core Concept**
The patient's presentation, including progressive headache and visual disturbances, suggests a space-occupying lesion in the suprasellar region. This is consistent with a craniopharyngioma, a type of brain tumor that often presents with calcifications on imaging.

**Why the Correct Answer is Right**
Craniopharyngiomas are typically benign tumors that arise from remnants of the Rathke's pouch, a precursor to the pituitary gland. They often present with calcifications on CT scans due to the presence of cholesterol crystals. The suprasellar region is a common location for these tumors, which can compress adjacent structures, including the optic chiasm, leading to visual disturbances.

**Why Each Wrong Option is Incorrect**
* **Option A:** Meningioma - While meningiomas can occur in the suprasellar region, they are less likely to present with calcifications and are more common in adults.
* **Option B:** Pituitary adenoma - These tumors are more commonly found in the sella turcica and are less likely to present with calcifications.
* **Option C:** Hypothalamic hamartoma - This rare tumor can present with visual disturbances, but it is less likely to be associated with calcifications and is more commonly found in the hypothalamus.

**Clinical Pearl / High-Yield Fact**
Craniopharyngiomas are often referred to as "honeycomb tumors" due to their characteristic appearance on imaging, which can resemble a honeycomb.

**Correct Answer: C. Craniopharyngioma**

✓ Correct Answer: A. Craniopharyngeoma
