“…Concha bullosa, which is an anatomic variant of a turbinate, is responsible for the formation of turbinate mucocele and pyogenic mucocele. Although it is very rare for the inferior turbinate to develop a concha bullosa[ 8 , 10 ], it is a relatively common anatomical variant in the middle turbinate, with an incidence varying from 14%-53.6%[ 8 ]. Moreover, concha bullosa is classified into three types, namely lamellar, bulbous, and extensive[ 12 , 13 ].…”

“…In our patients, nasal endoscopy could reveal turbinate hypertrophy; however, it needs to be differentiated from turbinate hypertrophy, ethmoidal mucocele, benign or malignant solid tumor (mesenchymal tumor or osseous tumor), meningoencephalocele, and dacryocyst mucocele, based on the patient’s symptoms and physical examination[ 6 , 12 , 14 , 21 - 23 ]. On CT scan, mucocele presents as non-enhancing, homogeneous, hypodense, well-defined, rounded, and expansile lesions[ 8 ]. Meanwhile, MRI clearly demonstrates the cystic nature of the lesion on T2 sequences[ 6 , 12 ].…”

“…According to the CT image, the cyst did not continue with the dacryocyst and dura mater, and the turbinate mucous cyst was surrounded by bone, so meningoencephalocele and dacryocyst mucocele were excluded[ 28 , 29 ]. Therefore, radiological examinations, such as CT or MRI, are essential for the accurate diagnosis of turbinate mucocele[ 1 , 3 , 8 , 9 ].…”

“…The sizes of these turbinates decrease by one-third consecutively; furthermore, the anterior position is successively retracted by one-third[ 1 - 3 ]. With the development of radiologic examinations, including computed tomography (CT) and magnetic resonance imaging (MRI), concha bullosa of the middle turbinate has been identified as a relatively common condition[ 3 - 7 ], whereas concha bullosa of the inferior turbinate is considered rare[ 8 - 10 ]. Furthermore, the development of mucocele or pyogenic mucocele from concha bullosa is considered extremely rare.…”

BACKGROUND Cases of turbinate mucocele or pyogenic mucocele are extremely rare. During nasal endoscopy, turbinate hypertrophy can be detected in patients with turbinate or pyogenic mucocele. However, in many instances, differentiating between turbinate hypertrophy and turbinate mucocele is difficult. Radiological examinations, such as computed tomography (CT) or magnetic resonance imaging (MRI), are essential for the accurate diagnosis of turbinate mucocele. Herein, we report three cases of mucocele or pyogenic mucocele of turbinate, including their clinical presentation, imaging findings, and treatments, to help rhinologists understand this condition better. CASE SUMMARY Three cases of turbinate and pyogenic mucocele were encountered in our hospital. In all patients, nasal obstruction and headache were the most common symptoms, and physical examination revealed hypertrophic turbinates. On CT scan, mucocele appeared as non-enhancing, homogeneous, hypodense, well-defined, rounded, and expansile lesions. Meanwhile, MRI clearly illustrated the cystic nature of the lesion on T2 sequences. Two patients with inferior turbinate mucocele underwent mucocele lining removal, while the patient with pyogenic mucocele underwent endoscopic middle turbinate marsupialization. The patients were followed up on the first, third, sixth month, and 1 year after discharge, and no complaints of headache and nasal congestion were reported during this period. CONCLUSION In conclusion, both CT and MRI are helpful in the diagnosis of turbinate or pyogenic mucocele. Additionally, endoscopic nasal surgery is considered to be the most effective treatment method.
