Abstract:

Collagenous broma (CF) is a benign soft tissue tumour with good prognosis. Preoperative imaging diagnosis is essential to avoid unnecessarily extended resection, which may result in irreversible functional damage. However, few studies published to date have reported on the imaging features, associated with this condition. We, therefore, present a patient with histologically proven CF on the dorsum of nose, associated with an unusual appearance on magnetic resonance imaging. Low signal intensity on T2-weighted images and rim enhancement on gadolinium-DTPA (Gd-DTPA) enhanced images are reported in some previously reported cases. However, the unique point about this case is the markedly enhanced nodule revealed in the middle part of the lesion ve hours after the administration of contrast media. To our knowledge, this is the rst description of late gadolinium enhancement features associated with the condition.
