“…Although Hisatomi and coauthors 38 were able to correlate the presentations of a range of radiological modalities, including MRI in a case of GOC associated with ameloblastoma, in another report they determined that MRI images of a GOC could not be distinguished from those of dentigerous, radicular and nasopalatine cysts. 39 Interestingly, distinguishing between these very lesions on the basis of conventional radiology would have presented little trouble in most cases. The GOC's infrequent association with unerupted teeth would have distinguished it from the dentigerous cyst.…”

“…Thus, AOT could be distinguished from COC on the basis of MRI. Demtigerous cyst showed an SI on T1WI and T2WI that was similar to that of AOT, but showed rim enhancement on CE-T1WI because its cyst wall was thin compared with that of AOT [10]. Thus, AOT could be distinguished from the dentigerous cyst by means of its thick enhancement compared with that of the dentigerous cyst.…”

The radiographical differentiation of adenomatoid odontogenic tumor (AOT) from dentigerous cysts, calcifying odontogenic cysts, calcifying epithelial odontogenic tumors, odontogenic keratocysts, and amelobastomas is sometimes difficult. We attempted to differentiate AOT from other lesions similar to AOT in radiographic findings using MRI.The MRI features of AOT in our 3 cases included homogeneous low SI in the cystic portion and homogeneous intermediate SI in the solid portion on T1WI, homogeneous high SI in the cystic portion and intermediate to slightly high SI in the solid portion on T2WI, and enhancement of only the solid portion on CE-T1WI although non of the sequences included SI of calcifications. The contrast index curves in the 3 cases of AOT showed a gradual increase to 300 s, which signified a benign tumor. These MRI features were characteristic features of AOT and might be a basis for differentiating AOT from the above possible lesions in radiographic examinations.

“…6,8,14 Nasolabial cysts appear on MRI as homogeneous intermediate intensity T1 signals and homogeneous high intensity T2 signals, similar to glandular odontogenic cysts and radicular cysts. 15 MRI is extremely useful in the differential diagnosis between nasolabial and nasopalatine cysts. The latter presents homogeneous high intensity T1 and T2 signals.…”

Cisto nasolabial é uma lesão rara, localizado próximo à cartilagem alar nasal e que se estende para o meato nasal inferior e sulco gengivo-labial superior. OBJETIVO: Apresentamos uma casuística de cisto nasolabial, com o objetivo de discutir a apresentação clínica, o diagnóstico e as técnicas cirúrgicas mais adequadas no tratamento desta doença. MATERIAL E MÉTODO: Estudo retrospectivo de oito pacientes com diagnóstico de cisto nasolabial, no período de janeiro/2000 a dezembro/2006. O diagnóstico foi sugerido por exame otorrinolaringológico e tomografia computadorizada (TC). Os pacientes foram submetidos a tratamento cirúrgico (enucleação) e o diagnóstico confirmado por exame histopatológico. RESULTADOS: Os sintomas predominantes foram: obstrução nasal, aumento de volume restrito ao vestíbulo nasal e dor à palpação local. O tempo médio de evolução dos sintomas foi de 26,2 meses. A TC evidenciou lesão cística, bem delimitada, com remodelação óssea em alguns casos. O tamanho médio do cisto foi de 2,18 cm. O seguimento médio no pós-operatório foi de 19,5 meses, sem recorrência da lesão. CONCLUSÃO: Os cistos nasolabiais são lesões pouco freqüentes. A maioria apresenta-se com aumento de volume bem localizado, dor local e obstrução nasal. Enucleação é o tratamento de escolha com baixos índices de recorrência.
