35 year old female patient Radha having children aged 5 and 6 years has history of amenorrhea and galactorrhea. Blood examination reveals increased prolactin. CT of head is likely to reveal :
**Core Concept**
Prolactinomas are a type of pituitary adenoma that secretes prolactin, leading to elevated prolactin levels in the blood. This condition can cause symptoms such as amenorrhea and galactorrhea in females, and is often diagnosed with a combination of clinical evaluation and imaging studies.
**Why the Correct Answer is Right**
The correct answer is likely to be a pituitary adenoma, specifically a prolactinoma. This type of tumor can cause an overproduction of prolactin, leading to the symptoms experienced by Radha. On a CT scan of the head, a prolactinoma would appear as a well-circumscribed mass in the stellar region of the sella turcica, which is the bony structure that houses the pituitary gland.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not likely to be the correct answer as it does not directly relate to the symptoms and diagnosis of prolactinoma.
**Option B:** This option may be a distractor, but the correct answer is more specific to the diagnosis of prolactinoma.
**Option C:** This option is incorrect as it does not accurately describe the imaging findings associated with prolactinoma.
**Clinical Pearl / High-Yield Fact**
The presence of galactorrhea in a female patient with amenorrhea should raise suspicion for a prolactinoma, and a CT scan of the head with contrast is often used as a diagnostic tool to confirm the presence of a pituitary adenoma.
**Correct Answer: C**. A pituitary adenoma.
