**Core Concept**
Stereotactic radiosurgery (SRS) is a non-invasive, precise radiation therapy technique used to treat various conditions affecting the brain and central nervous system. It involves delivering high doses of radiation to a specific target area with minimal damage to surrounding tissues.

**Why the Correct Answer is Right**
SRS is a valuable treatment option for **metastatic brain tumors** (Option A), allowing for precise targeting of multiple lesions with minimal radiation exposure to surrounding brain tissue. It is also effective in treating **arteriovenous malformations (AVMs)** (Option B), which are abnormal connections between arteries and veins that can cause bleeding and other complications. Additionally, SRS is used to treat **trigeminal neuralgia** (Option C), a chronic pain condition caused by compression or irritation of the trigeminal nerve. The Gamma Knife and CyberKnife are examples of SRS systems used for these treatments.

**Why Each Wrong Option is Incorrect**
**Option A:** Metastatic brain tumors can also be treated with other modalities like surgery, whole-brain radiation therapy, or chemotherapy, but SRS is a preferred option for patients with limited brain metastases.
**Option B:** AVMs can also be treated with surgery or endovascular embolization, but SRS is often reserved for patients with high-risk AVMs or those who are not good candidates for surgery.
**Option C:** While SRS can be used to treat trigeminal neuralgia, it is not the only treatment option; other treatments include medication, microvascular decompression surgery, or percutaneous balloon compression.

**Clinical Pearl / High-Yield Fact**
SRS is a valuable treatment option for patients with brain tumors or other conditions affecting the central nervous system, offering precise targeting with minimal radiation exposure to surrounding tissues.

**✓ Correct Answer: D. All of the above**
