CT – Rhinopathy and Neoplasia of the Nasal cavity with Brain Involvement in a 15 year old FS

Case Study

CT – Rhinopathy and Neoplasia of the Nasal cavity with Brain Involvement in a 15 year old FS

History of intermittent blood-tinged mucoid discharge and congested breathing, of 2-3 months duration. Physical exam showed minimal airflow through both nostrils. CBC and chemistry were WNL.

Image Interpretation

CT of the skull: Nasal Cavity: Primarily right-sided mass effect; soft tissue attenuating, causing
turbinate destruction, deviation and destruction of the boney nasal septum, extending
into left nasal cavity (minimally), causing multifocal lysis of the nasal vault.
Frontal sinuses: severe involvement of the right side, complete occlusion of lumen,
lysis of the dorsal frontal bone.
Calvarium: Normal.
Brain: Lysis of the right cribriform plate and extension of the mass into the brain. No
deviation of the falx cerebra.
Lymph nodes: Enlarged right retropharyngeal LN (R=8 mm, L=3mm).
Soft tissues are normal

DX

Aggressive primarily right sided rhinopathy and right sided adenopathy (possible metastatic lesion) 2. Carcinoma (or lymphoma) causing turbinate, nasal vault, frontal bone and cribriform plate destruction with brain involvement

Outcome

Recommendations: Rhinoscopy for biopsy confirmation. Consider radiation therapy consultation/referral

Clinical Differential Diagnosis

R/O tumor vs infectious vs fungal vs other
