“…The maxillary antrum is a relatively unfrequent site for mucocele formation, accounting for 10 percent or less of mucoceles. 7,8 In our study, mucoceles were seen frequently in frontoethmoidal sinus followed by ethmoidal location then frontal sinus.…”

Introduction: Mucoceles are cystic masses developing after obstruction of the sinus ostium. The symptoms are not specific. Computed Tomography scan (CT scan) and Magnetic Resonance Imaging (MRI) confirm the diagnosis. Objectives: We herein review the radiologic characteristics of mucoceles in CT scan and MRI. Materials and Methods: We report a retrospective study of 43 patients diagnosed with paranasal sinuses mucoceles. CT scans were performed for all patients, but MRI was carried out only in selected cases. Results: Our study was constituted of 27 males and 16 females with a mean age of 47 years. The CT scan appearence of mucoceles were in all cases as a well circumscribed expansile sinus mass with an effect on the neighbor bone structure. This mass was hypodense in 26 cases, isodense in 14 cases and hyperdense in 3 patients. The paranasal sinuses most frequently affected in our series were the fronto-ethmoidal sinuses. The most affected bone eroded was the lamina papiracea. Intracranial extension was seen in four cases. CT scan allowed to predict the cause of mucoceles in some cases and to provide information about anatomic variants. MRI was realized for 15 patients in addition to the CT scan. It allowed to study the extension of mucoceles to the neighboring organs especially orbital and endocranial ones. Conclusion: The presentations of mucoceles on imaging are quite variable. CT scan provides precious information about the location, bone erosion and extension of the mucoceles. MRI is indicated in some cases especially in cases of orbital or cranial extension.

“…Mococeles have the typical radiographic appearance of a fully opacified sinus with evidence of rounded or ovoid expansion and bone erosion. The bony outline becomes more rounded as the bone remodels in response to growing pressure within the sinus cavity [20]. Radiologically all malignant lesions are characterized by soft tissue mass with aggressive bone destruction of the adjacent walls.…”

Unilateral sinonasal pathology are common presentations but are regarded with caution as neoplastic conditions during their early stages may mimic an inflammatory pathology. The aim of the review was to analyse the varied presentations of patients with unilateral nasal mass and to identify features suggestive of neoplastic pathology. A retrospective review of all cases of unilateral nasal mass/polyp from Jan 09 to Jan 10 presenting at a tertiary care hospital were analysed. The patients were grouped as per their histopathological diagnosis as inflammatory and neoplastic. The demographic data, presenting symptoms, radiological and histopathological findings were compared between the two groups. Out of the 53 patients of unilateral nasal mass, 44 (83.1%) had inflammatory conditions and 9 (16.9%) had neoplastic conditions. Benign nasal polyp and inverted papilloma were the commonest inflammatory and neoplastic condition. Neoplastic conditions were significantly commoner in males (P = 0.0315) and in the age group above 50 years (P = 0.0046). Epistaxis and extranasal symptoms like facial pain, dental and orbital complaints were found to be significantly higher in neoplastic conditions. Neoplastic lesions of nose and paranasal sinus are one of the most challenging conditions that otolaryngologists have to diagnose and treat due to their hidden nature and late presentations. In our review neoplastic conditions were found to be higher in elderly male with epistaxis, extranasal symptoms and presence of extensive soft tissue involvement and bony destruction on CT scan. The clinician should have a high index of suspicion to rule out a neoplastic aetiology in all cases of unilateral nasal mass.

“…Most mucocoeles do not show contrast enhancement and in fact the administration of contrast medium is rarely necessary. Bony detail is an added advantage of CT [4]. An opaque maxillary sinus without bone erosion invites the diagnosis of sinusitis, retention cysts and antrochoanal polyps.…”

Maxillary antral mucocoeles have an incidence of only 3-10%. Mucocoeles are more commonly seen in the frontoethmoidal region. We present one such rare case of a 52-year-old lady who came to us with complaints of pain and swelling of the left cheek of 4 months duration. Clinical examination and investigation revealed a giant maxillary sinus mucocoele which was duly treated surgically. We discuss its classical presentation and management since such large mucocoeles are not often seen in the maxillary sinus.
