Unilateral Sinonasal Disease Without Bone Destruction: Differential Diagnosis Using Diagnostic Imaging and Endonasal Endoscopic Biopsy

Clinical value of office‐based endoscopic incisional biopsy in diagnosis of nasal cavity masses

“…There are other reports in which the clinical impression with history, physical examination, and imaging was nasal polyp, but the pathology result was tumor 11–14. When patients had unilateral sinonasal lesions without bone destruction, neither CT nor MRI was useful in diagnosis of neoplasms except angiofibromas 15. The authors concluded that endonasal endoscopic biopsy is a qualitative diagnostic tool in the diagnosis of sinonasal neoplasm 15.…”

Malignant lymphoma with the MRI findings mimicking inflammatory disease: a case report

“…MRI is benefical for diagnosing nasal sinus tumors because of its higher-density resolution than that of CT. 1 Moreover, imaging tests are useful for diagnosing early-stage malignant lymphomas of the paranasal sinuses because they present with few symptoms. The CT findings of malignant lymphoma include a geographic or moth-eaten pattern of bone destruction with permeative bone processes.…”

Odontogenic sinusitis is a common cause of unilateral sinus disease with maxillary sinus opacification

“…In addition, although ODS has been reported to present more commonly unilaterally, its incidence has rarely been discussed in the USD literature. USD has generally been considered neoplastic until proven otherwise, and, when biopsies return negative for neoplasia, the condition has been considered inflammatory. However, USD studies have often omitted the differential diagnosis of inflammatory USD, with ODS rarely being discussed.…”
