CT findings in two cases of lobular capillary haemangioma of the nasal cavity: focusing on the enhancement pattern.

Lobular capillary haemangioma, known as pyogenic granuloma, is a relatively common benign vascular neoplasm that is composed of hyperplastic clusters of capillaries arranged in a lobular architectural pattern. Most mucosal lobular capillary haemangioma (LCH) of the head and neck arise in the oral cavity, but the nasal cavity involvement is rare. We report here on the CT imaging findings of two cases of LCH involving the nasal cavity, with an emphasis being placed on the different pattern of enhancement of the tumour on the enhanced CT scans.
