We report two cases of ethmoidal cephaloceles. Ethmoidal cephaloceles are very rare and most commonly present with recurrent episodes of meningitis or sometimes as a nasal mass. Diagnosis is made at MR and CT. Such imaging studies should be obtained in patients with recurrent meningitis or patients with polypoid nasal lesions prior to biopsy.

Malignant fibrous histiocytoma (MFH) is a rare and potentially highly malignant sarcoma. The authors report 6 cases of MFH in various sites: two in the chest wall, one in the pelvis, two in the gluteal zones and one on the scalp. Ultrasonography and computed tomography were the main imaging methods used in the assessment of the structure and extension of the tumor. A poor prognosis was noted in four cases: death within a few months in the two thoracic sites, recurrence in the pelvic and scalp lesions, radical surgery allowed recovery in two cases. A review of the literature showed that MRI and CT are complementary in the initial staging and follow-up of these patients.
