Bifid ribs, multiple radiolucent lesions of the jaws, multiple basal cell nevi and falx cerebri calcification are found in
## **Core Concept**
The question describes a syndrome characterized by a combination of skeletal, dermatological, and radiological findings. The key features mentioned include bifid ribs, multiple radiolucent lesions of the jaws, multiple basal cell nevi, and calcification of the falx cerebri. This constellation of symptoms points towards a specific genetic disorder.
## **Why the Correct Answer is Right**
The correct answer, **Gorlin syndrome (also known as Basal Cell Nevus Syndrome)**, is a genetic disorder that affects multiple systems. It is characterized by:
- **Skeletal abnormalities**: Including bifid ribs, which are a classic feature.
- **Dermatological manifestations**: Such as multiple basal cell nevi, which are a hallmark of the syndrome.
- **Radiological findings**: Including multiple radiolucent jaw lesions, often referred to as jaw keratocysts or odontogenic keratocysts, and calcification of the falx cerebri, a type of intracranial calcification.
## **Why Each Wrong Option is Incorrect**
- **Option A**: This option is incorrect because it does not correspond with the known associations of Gorlin syndrome or similar conditions that present with the described features.
- **Option B**: Similarly, this option does not match the clinical presentation outlined in the question.
- **Option C**: Not applicable as this is the correct answer.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl for this question is that Gorlin syndrome is associated with an increased risk of developing **basal cell carcinoma**, and patients often present with multiple **jaw keratocysts**. The syndrome is inherited in an autosomal dominant pattern and is caused by mutations in the **PTCH1 gene**. Early recognition is crucial for managing the complications of this syndrome.
## **Correct Answer:** . **Gorlin syndrome**
