Imaging modality correlations of an odontogenic keratocyst in the nevoid basal cell carcinoma syndrome: a family case report.

Multiple maxillary and mandibular cysts are principle features of nevoid basal cell carcinoma syndrome (NBCCS; Gorlin-Goltz syndrome). We present a family case report of NBCCS with odontogenic keratocyst where the findings on plain films, CT, clinical, and histopathologic examinations are compared and analyzed. The systemic manifestations included frontal bossing, odontogenic keratocyst, ectopic calcification in 1 patient, and bifid rib in 1 patient. CT examination displayed aspects of bone morphology not visible on the plain films. Odontogenic keratocyst diagnosis was confirmed by histopathological examination. The features identified by these combined clinical, imaging, and histologic findings are helpful in identifying an NBCCS patient, distinguishing keratocyst from others cysts or neoplasic lesions, and can therefore influence surgical management. NBCCS is a rare autosomal dominant cancer predisposition syndrome, which is important to recognize when a patient has multiple odontogenic keratocysts, because lifelong monitoring is essential for patient management.
