Question

Neurofibromatosis 1 criteria except

• A. Brain tumor
• B. Acoustic neuromas
• C. Pseudoarthrosis
• D. Cafe-au-lait spots

Answer 1

The Correct Option is B

To determine which of the listed options is not a criterion for Neurofibromatosis type 1 (NF1), we need to know the established diagnostic criteria for NF1. Here is a concise explanation:

• Café-au-lait spots: These are light brown skin patches and are a common criterion for NF1. An individual with NF1 typically has six or more of these spots.
• Brain tumor: While brain tumors can occur with NF1, they are not used as a primary diagnostic criterion.
• Pseudoarthrosis: This refers to a condition where there is abnormal movement at the site of a fracture, and it is considered as a diagnostic criterion of NF1.
• Acoustic neuromas: These tumors, also known as vestibular schwannomas, are typically associated with Neurofibromatosis type 2 (NF2), not NF1.

Given this information, the correct answer is that Acoustic neuromas are not a criterion for NF1.
