[Imaging of aneurysms and dissections of the aorta. Part 1--Aneurysms of the abdominal aorta].
The authors review the main imaging findings of aneurysms and dissections of the aorta. Based on the experience and imaging techniques available in their institution (Conventional Radiology, Sonography and Computed Tomography), they try to make a decision tree of radiologic procedures in ambulatory and emergency patients. Nowadays, in the majority of situations, these techniques allow the Radiologist to make the correct diagnosis, detect the complications and evaluate the patients in the pre and post-surgical phases. Other imaging techniques not available in their institution, such as Magnetic Resonance Imaging and Aortography, will be mentioned in view of their usefulness in some specific situations.
Posterior fossa hemangioblastomas: MR imaging.
The magnetic resonance (MR) imaging findings of 18 surgically proved posterior fossa hemangioblastomas (15 patients) were retrospectively analyzed and correlated with computed tomographic (ten patients) and angiographic (eight patients) findings. Thirteen tumors were located in the cerebellar hemisphere, three in the vermis, and two in the medulla with associated syrinxes. Three patients had von Hippel-Lindau disease, two of whom had multiple cerebellar hemangioblastomas. Seven hemangioblastomas appeared as solid tumors, six as solid masses with central cysts, and five as cysts with mural nodules. Abnormal tumor vessels, with characteristic signal void, were demonstrated in 13 tumors. Associated hemorrhage was present in four tumors. Although angiography is usually required for the diagnosis and preoperative assessment of this tumor, MR imaging demonstration of a posterior fossa mass with abnormal vessels should suggest the diagnosis of hemangioblastoma. Moreover, the combination of a peripheral posterior fossa cyst with a mural nodule supplied by enlarged vessels may be pathognomonic.
[Broncho-splenic fistula caused by hydatidosis].
To our knowledge, this is the first case report of a broncho-splenic fistula of hydatid origin. We discuss the clinical, radiological and therapeutic aspects of this rare complication of hydatid disease.
