A 25 years old male c/o recurrent abdominal pain but biochemical assays and ultrasound abdomen is normal. He also complains of constant headache. He suddenly complains of loss of vision of bilateral eyes. Ophthalmologist finds nothing on examination. Symptoms are most probably due to ?
**Core Concept**
The patient's presentation of recurrent abdominal pain, constant headache, and sudden loss of vision in both eyes suggests a condition that affects multiple systems and may have a vascular or neurological origin. The key concept here is the involvement of the optic nerve and the possibility of a condition that affects the blood vessels supplying the brain.
**Why the Correct Answer is Right**
The symptoms described are highly suggestive of **Migraine with Aura**, a type of headache disorder that involves the presence of neurological symptoms, including visual disturbances, before the headache. The loss of vision in both eyes is likely due to the involvement of the optic nerve, which is a common feature of migraine auras. The recurrent abdominal pain and constant headache may be related to the underlying migraine disorder, which can also cause gastrointestinal symptoms and headaches between episodes of aura.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not explain the sudden loss of vision in both eyes. Migraine with aura typically involves visual disturbances, but these are usually unilateral and affect one eye at a time.
**Option B:** This option is incorrect because it does not account for the recurrent abdominal pain and constant headache. While temporal arteritis can cause sudden loss of vision, it is typically associated with jaw claudication and scalp tenderness, which are not mentioned in this case.
**Option C:** This option is incorrect because it does not explain the sudden loss of vision in both eyes. Cluster headaches are severe and unilateral, but they do not typically cause bilateral visual loss.
**Option D:** This option is incorrect because it is too nonspecific and does not account for the patient's symptoms. While "vascular" conditions can cause sudden visual loss, this option does not provide enough information to explain the patient's presentation.
**Clinical Pearl / High-Yield Fact**
Migraine with aura is a common cause of sudden visual loss in young adults, and it is essential to consider this diagnosis in patients with recurrent headaches and visual disturbances. The presence of aura symptoms, including visual disturbances, can help differentiate migraine from other causes of headache.
**Correct Answer: A. Migraine with Aura**
