On the paranasal CT scan, a lobular mass sized approximately 2.5 x 3.6 cm with the same density as the bone tissue was observed which completely covered the right ethmoid cells, displaced the nasal septum to the left, extended medially to the septum and laterally to the lamina papyracea, and was characterized by significantly hyper-dense and sporadically hypo-dense areas (Figures 1 and 2).

The mass was removed from the adjacent tissues with the aid of curettage and drilling; after that, it was removed in two pieces from the nostrils (Figure 3).
