The persistent stapedial artery is a rare congenital vascular anomaly that may present as a pulsatile middle ear mass or that may appear as an incidental finding. Five cases of persistent stapedial artery are presented. The CT findings include the absence of the ipsilateral foramen spinosum and a soft-tissue prominence in the region of the tympanic segment(More)
Cataclysmal hemorrhage occurred in eight patients with known aggressive squamous cell tumors of the head and neck. Angiography showed neovascularity, narrowing, beading of affected arteries, and pseudoaneurysms. Postembolization residual stump formation was seen in a few patients. A total of 11 embolization procedures were performed in these eight patients.(More)
The authors studied retrospectively 42 patients with the magnetic resonance (MR) diagnosis of myelomalacia. Depending on MR findings, the patients were grouped into early, intermediate, and late stages of myelomalacia. Early stage myelomalacia patients presented with high intensity signal changes on T2-weighted images involving the width of the affected(More)
The authors present two patients with Paget disease, both showing lytic changes in the calvarium. On T1 contrast sequences, the first patient demonstrated an extraaxial soft tissue mass in the temporooccipital region. This abnormality was hypointense to the adjacent normal diploic tissue. The second patient demonstrated a hypointense frontal abnormality on(More)
Two cases of craniofacial mucormycosis are presented, stressing computed tomographic (CT) and angiographic findings. In the first case, successful embolization of a sphenopalatine artery pseudoaneurysm is shown. The second case demonstrates CT findings of ethmoidal sinus and frontal lobe inflammatory change. Ophthalmic artery occlusion is show. Obstructive(More)
The authors examined 19 patients with diffuse histiocytic lymphoma of the brain, including 8 with primary disease and 11 with secondary disease. Both primary disease and secondary disease involving the brainstem and deep nuclei exhibited the characteristic CT appearance, consisting of a large, solid, homogeneously enhanced mass with varying amounts of(More)
Our technique is similar to that described by Debrun et al. [?] and consists of the introduction of a microleak balloon catheter by way of a transfemoral approach, placing the balloon above the takeoff of the ophthalmic artery so that chemotherapy can be delivered to an intracranial malignant neoplasm without causing chemosis and/or ophthalmoplegia to the(More)
A 10-year-old boy was admitted with left leg pain and fever of 38.9°C. The initial clinical impression was cellulitis. Laboratory findings included hemoglobin of 5 gjdl and white blood cell count of 206,OOOjmma The spleen was enlarged and multiple cervical lymph nodes were palpable. Bone marrow pathology was interpreted as acute myelocytic leukemia. The(More)
