Diagnosis & Imaging
Nasal dermoid
A nasal dermoid is a dermoid cyst specifically in the nasal region that can have a tract toward the skull base.
In short: Nasal dermoid
- It occurs in the nasal region.
- It can have a tract extending toward the skull base.
- Imaging assesses any connection before treatment.
- It is part of the differential for a nasal mass.
What it is
It is a dermoid cyst located specifically in the nasal region. It can sometimes have a tract (a small channel) extending toward the skull base, which imaging assesses.
Understanding Nasal dermoid
Because a nasal dermoid can have a tract toward the skull base, imaging is used to determine whether and how far it extends before treatment is planned. It is part of the differential diagnosis for a nasal mass, alongside encephalocele and nasal glioma. As with all nasal masses in children, imaging precedes any procedure to characterize the lesion and check for any connection toward the brain.
Why it matters
Understanding nasal dermoid helps families see why imaging assesses the full extent of a nasal mass, including any tract toward the skull base, before planning treatment.
Common questions
Where is a nasal dermoid?
In the nasal region.
Can it extend toward the skull?
It can have a tract toward the skull base.
Why image it?
To assess any connection before treatment.
Bottom line
A nasal dermoid is a nasal-region dermoid cyst that can have a tract toward the skull base, assessed by imaging.
