CT Report Findings Survey and post-i.v. contrast CT of the skull


Nasal Cavity: No fluid or mass seen. No turbinate lysis or deviation or lysis of the septum

Oral cavity: Mass: expansile mass associated with right rostral mandible; lesion is centered on tooth 404. Aggressive appearing , mandible lysis and spiculated periosteal proliferation. 2.5 cm long x 2 cm wide, gross margins limited by symphysis. Caudally extends into region of tooth 405


Dentition: normal appearing. No periodontal lysis is seen. No missing teeth seen

Orbital structures appear normal.

Frontal sinuses: Right side and left side air filled. No frontal bone lysis seen

Ventral nasal meatus: air filled

Nasopharynx: air filled

Nasal vault: No maxilla, nasal bone or hard palate lysis seen

Cribriform plate: no lysis seen

Brain: No evidence of aberrant meningeal contrast enhancement or deviation of the falx. Pituitary gland normal size (6.0 mm tall)

Tympanic Bullae: air filled and no bulla wall lysis or thickening seen. hyperostotic tympanic bone spicules (HTBS)

Conclusion

Oral mass: aggressive, right side, mandible; consider

  1. neoplasia: SCC, melanoma, FSA

  2. tooth based neoplasia (e.g., epulis)

  3. periapical abscess thought less likely Recommendations incisional biopsy pending histology, 1 cm excisional margins would include tooth 304 and 406
