We report the imaging findings of a desmoplastic fibroma (DF) of the mandible in a 3 years old girl. DF of bone is a rare, no-metastasizing but locally aggressive tumor. Hypercellularity, nuclear pleomorphism, mitotic activity, and traces of odontogenic epithelium and bony tissue are absent.

MDCT arthrography of the wrist: diagnostic accuracy and indications.

Purpose: To evaluate the diagnostic accuracy and indications of arthrography with Multidetector Computed Tomography (arthro-MDCT) of the wrist in patients with absolute or relative contraindications to magnetic resonance imaging (MRI) studies and in patients with periarticular metal implants using diagnostic arthroscopy as the gold standard.

Materials And Methods: After intra-articular injection of iodixanol and volumetric acquisition, 43 wrists in patients of both genders (18 females, 25 males, age range 32-60 years) were examined with a 16-detector-row CT scanner. Fifteen patients had prior wrist surgery.
