An infant has a firm, non-pulsatile, pinkish-grey mass in the right nasal cavity. The mass does not increase in size and there is no bulge at the root of the nose when the baby cries (negative Furstenberg test). The most likely diagnosis is:
- A Nasal glioma ✓
- B Meningoencephalocele
- C Nasal dermoid
- D Capillary haemangioma
Correct answer: A. Nasal glioma
Explanation
C nasal glioma is heterotopic glial tissue that lost its intracranial connection during embryogenesis, leaving either no stalk or only a fibrous one. Because there is no communication with the subarachnoid space, it does not expand with crying or straining, giving a negative Furstenberg test. An encephalocele retains a CSF-filled connection to the ventricles, becomes tense and enlarges with crying, and gives a positive test. Dermoids are typically midline with a pit or hair-bearing dimple.
