Arrested pneumatization of the sphenoid sinus is a common finding that may mimic disease on CT scans. This study reviews imaging features to help differentiate this normal variant from actual pathology.
Area of Science:
- Radiology
- Anatomy
- Otolaryngology
Background:
- Arrested pneumatization of the sphenoid sinus is an anatomical variant.
- It can be misdiagnosed as pathology on imaging.
- Accurate diagnosis is important for patient management.
Purpose of the Study:
- To present cases of arrested pneumatization of the sphenoid sinus.
- To discuss imaging findings on CT scans.
- To provide differential diagnoses for suspected pathology.
Main Methods:
- Review of suspected arrested pneumatization cases.
- Analysis of cone beam CT and multidetector CT scans.
- Correlation of imaging findings with anatomical knowledge.
Main Results:
- Arrested pneumatization presents specific characteristic imaging findings.
- These findings can be distinguished from inflammatory or neoplastic processes.
- Differential diagnosis includes sinusitis, cysts, and tumors.
Conclusions:
- Arrested pneumatization is a benign finding.
- Radiologists should be familiar with its imaging appearance.
- Correct identification avoids unnecessary interventions.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
