**Core Concept**
Pseudotumour cerebri, also known as idiopathic intracranial hypertension (IIH), is a condition characterized by increased intracranial pressure without any obvious cause. Various factors can contribute to its development, including hormonal imbalances, medication side effects, and obesity.

**Why the Correct Answer is Right**
Among the medications listed, **tetracycline antibiotics** are known to be associated with pseudotumour cerebri. This is thought to be due to their effect on the intracranial pressure and the cerebrospinal fluid dynamics. The exact mechanism is not fully understood, but it is believed to involve the alteration of the blood-brain barrier and the accumulation of cerebrospinal fluid.

**Why Each Wrong Option is Incorrect**
**Option A:** **Vitamin A** derivatives, such as isotretinoin, are known to cause pseudotumour cerebri. This is a well-documented side effect of these medications.
**Option B:** **Corticosteroids** can also contribute to the development of pseudotumour cerebri, particularly in cases of long-term use or high doses.
**Option C:** **Minoxidil**, a topical vasodilator, has been associated with pseudotumour cerebri in some cases, although the exact mechanism is unclear.

**Clinical Pearl / High-Yield Fact**
Pseudotumour cerebri can be a challenging diagnosis to make, as the symptoms can be non-specific and overlap with other conditions. A high index of suspicion and a thorough medical history are essential for identifying patients at risk.

**Correct Answer:** D. Tetracycline antibiotics are not typically associated with pseudotumour cerebri, whereas the other options have a known link to this condition.
