Abstract:
Inflammatory pseudotumor is a benign neoplasm composed of fibroblasts, histiocytes, and inflammatory cells. Its occurrence in the paranasal sinuses is rare. We report a case of a 15-year-old boy with a maxillary sinus inflammatory pseudotumor that simulated an aggressive neoplasm on CT scan.
Insights
Inflammatory pseudotumor, a benign condition, rarely affects the paranasal sinuses. A case report details a maxillary sinus pseudotumor mimicking an aggressive neoplasm in a young patient.
Area of Science:
- Pathology
- Radiology
- Otolaryngology
Background:
- Inflammatory pseudotumor is a rare, benign neoplasm characterized by a proliferation of fibroblasts, histiocytes, and inflammatory cells.
- Paranasal sinus involvement by inflammatory pseudotumor is exceptionally uncommon, posing diagnostic challenges.
Observation:
- A 15-year-old male presented with a lesion in the maxillary sinus.
- Computed tomography (CT) imaging revealed a mass that appeared aggressive and infiltrative.
Findings:
- Histopathological examination confirmed the diagnosis of inflammatory pseudotumor.
- The imaging features on CT scan mimicked those of a malignant neoplasm, highlighting a potential diagnostic pitfall.
Implications:
- This case underscores the importance of considering benign conditions like inflammatory pseudotumor in the differential diagnosis of paranasal sinus masses.
- Accurate radiological interpretation and thorough histopathological analysis are crucial for appropriate patient management and avoiding unnecessary aggressive treatment.
