Dripping candle wax lesion on spine:
**Core Concept**
A dripping candle wax lesion, also known as an epidural lipomatosis, is a rare condition characterized by the accumulation of excess epidural fat in the spinal canal. This can lead to spinal cord compression and neurological symptoms. The condition is often associated with Cushing's syndrome, obesity, and other conditions that cause increased cortisol levels.
**Why the Correct Answer is Right**
Epidural lipomatosis occurs when there is an abnormal accumulation of adipose tissue in the epidural space, which can compress the spinal cord and nerves. This compression can lead to symptoms such as back pain, numbness, and weakness in the legs. The condition is often associated with Cushing's syndrome, a condition caused by excess cortisol levels, which can stimulate the growth of adipose tissue. The excess fat can accumulate in the epidural space, compressing the spinal cord and leading to neurological symptoms.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not accurately describe the condition characterized by the accumulation of excess epidural fat in the spinal canal.
* **Option B:** This option is incorrect because it does not accurately describe the condition, and also because it is a less common condition that is not typically associated with the symptoms described.
* **Option C:** This option is incorrect because it is a type of tumor that occurs in the spinal cord, and is not related to the accumulation of excess epidural fat.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that epidural lipomatosis can be a rare but serious complication of Cushing's syndrome, and should be considered in patients with symptoms of spinal cord compression who also have signs of excess cortisol levels.
**Correct Answer: D.**
