Pulmonary congenital cystic disease in adults. Spiral computed tomography findings with pathologic correlation and management.

Purpose: The aim of this study was to assess the computed tomography (CT) features of intrapulmonary congenital cystic diseases in adults and to correlate the imaging features with the pathological findings, with emphasis on the oncogenic potential of the lesions.

Materials And Methods: We retrospectively reviewed the CT scans in three institutions from August 1996 to December 2008, of nine patients (six men, three women; mean age 48.6 years; range 26-75 years) who had histological diagnosis of pulmonary cystic disease after surgery.

Magnetic resonance imaging features of myxoid leiomyoma of the vagina: A case report.

We report a rare case of a voluminous vaginal myxoid leiomyoma in a 27-year-old nulliparous woman. Magnetic Resonance Imaging (MRI) revealed a mass arising from the vagina, with inhomogeneous signal intensity on spin-echo T1W and T2W images. MRI accurately defined the tissue planes between the lesion and the adjacent structures and suggested its benign nature.

Simultaneous occurrence of renal oncocytoma and B small cell lymphoma in the same kidney: report of two cases.

Two cases of simultaneous occurrence of oncocytoma (OC) associated with small B-cell lymphoma in the same kidney were investigated. Computed tomography, performed for staging purposes, incidentally revealed a small hypo- and hyperattenuating renal mass. Diagnosis of OC was performed on the specimen by morphology, immunohistochemistry and electron microscopy.

Small (< or = 2 cm) atypical hepatic haemangiomas in the non-cirrhotic patient: pattern-based classification scheme for enhancement at triple-phase helical CT.

Purpose: The aim of this study was to determine by triplephase helical computed tomography (CT) the appearance of atypical small (< or = 2 cm) hepatic haemangiomas (HHs) in the non-cirrhotic patient.

Materials And Methods: We retrospectively reviewed the hepatic arterial-dominant phase (HAP), portal venous phase (PVP) and delayed-phase (DP) helical CT images of 47 patients with 52 atypical small (< or = 2 cm) HHs associated with 34 typical small HHs. Images were assessed to identify the patterns of enhancement of atypical HHs and correlate their appearance with that of typical small HHs in the delayed phase.

Clinical Outcome of High Risk Gastrointestinal Stromal Tumor in a Meckel's Diverticulum.

We describe a seven years follow-up of a high risk gastrointestinal stromal tumor in a Meckel's diverticulum in a 68-year-old man with abdominal pain and vomiting. The patient was operated in emergency for peritonitis due to perforation of small intestine and treated with imatinib mesylate. The metastatic progression of the disease demonstrated the value of prognostic indicators (mitotic rate >10/50 high power field, necrosis and 8 cm in maximum diameter) for assessing risk of aggressive behaviour.

CT angiography versus colour-Doppler US in acute dissection of the vertebral artery.

Purpose: Conventional digital subtraction angiography (DSA) still represents the criterion standard for the diagnosis of vertebral artery dissection (VAD), but the main drawbacks of this technique include invasiveness, patient discomfort and risk of complications. We evaluated the potential of multidetector computed tomography angiography (CTA) as a noninvasive tool providing high-resolution images of the arterial lumen and wall by comparing the diagnostic accuracy of CTA and colour-Doppler ultrasonography (CDUS) in detecting acute VAD.

Materials And Methods: We retrospectively reviewed 15 cases of VAD in 15 patients (five men and ten women, age range 28-58 years) who came to our attention between August 2001 and September 2005.

Carotid artery stenting: first consensus document of the ICCS-SPREAD Joint Committee.

Background And Purpose: The prevention of stroke and the correct treatment of carotid artery stenosis represent today a major debate in cardiovascular medicine. Beside carotid endarterectomy, carotid angioplasty and stenting is becoming more widely performed for the treatment of severe carotid obstructive disease, and is now accepted as a less invasive technique that may provide an alternative for selected patients, particularly those with significant comorbidities. An Italian multidisciplinary task force, in which converged the most representative scientific societies involved in carotid treatment, was created to provide neurologists, radiologist, cardiologists, vascular surgeons, and all those involved in prevention and treatment of carotid disease with a simple, clear and updated evidence-based consensus document.

Three-dimensional analysis of pulmonary nodules by MSCT with Advanced Lung Analysis (ALA1) software.

Purpose: The purpose of this study was to test the reproducibility of the three-dimensional (3D) Advanced Lung Analysis software (3D-ALA, GE Healthcare) in the estimation of pulmonary nodule volume.

Materials And Methods: We retrospectively reviewed the unenhanced multislice CT scans (Lightspeed Pro 16 GE) of 77 patients with a solitary pulmonary nodule (n=71) or metastatic pulmonary disease (n=6). A total of 103 pulmonary nodules (19 well-circumscribed, 45 juxtavascular and 39 juxtapleural) were analysed grouped into five classes based on diameter: <5 mm, 10 nodules (9.

Long-term follow-up of atherosclerotic renovascular disease. Beneficial effect of ACE inhibition.

Background: Patients with atherosclerotic renovascular disease (ARVD) are almost invariably treated by revascularization. However, the long-term outcomes of this approach on survival and progression to renal failure have not been investigated and have not been compared with that of a purely medical treatment. The aim of this observational study was to investigate factors affecting long-term (over 5 years) outcome, survival and renal function of patients with ARVD treated invasively or medically.

Imaging evaluation of post pancreatic surgery.

The role of several imaging techniques in patients submitted to pancreatic surgery with special emphasis to single-slice helical computed tomography (CT) and multidetector-row CT (MDCT) was reviewed. Several surgical options may be performed such as Whipple procedure, distal pancreatectomy, central pancreatectomy, and total pancreatectomy. Ultrasound examination may be used to detect peritoneal fluid in the early post-operative period as well as lesion recurrence in long-term follow-up.

Percutaneous treatment of carotid stenosis with protection system: preliminary experience.

Purpose: To assess the feasibility, safety, and efficacy of carotid artery stenting with filter device.

Materials And Methods: Between May 2001 and July 2002, a total of 96 consecutive patients (100 lesions) who presented with symptomatic >70% diameter stenosis, asymptomatic >90% diameter stenosis or post-endarterectomy as well as post-radiotherapy hemodynamically significant stenosis underwent carotid artery stenting with filter protection at our institute. The mean age of the patients was 72 (range 51-91).

Postpartum ovarian vein thrombosis with simultaneous pyelocaliectasis: diagnosis and follow-up by MR imaging. Case report and literature review.

We describe the critical role of MR imaging in a case of postpartum ovarian vein thrombosis (OVT) with concomitant pyelocaliceal ectasia. MR imaging confirmed the diagnosis suspected on the basis of ultrasonography and computed tomography by demonstration of a subacute clot with high signal intensity within the right ovarian vein and its complete resolution after anticoagulant therapy. MR imaging is a useful noninvasive, accurate tool for the diagnosis and follow-up of this potentially life-threatening condition, providing information helpful for choosing a prompt medical treatment rather than a surgical therapy.

Emergencies in the retroperitoneum: assessment of spread of disease by helical CT.

Acute pancreatitis, leaking abdominal aortic aneurysm, and renal trauma frequently occur in the setting of patients with abdominal nontraumatic and traumatic injury; it represents the most urgent conditions that may determine the presence of fluid collections or haematoma in the retroperitoneum. Single spiral CT and multidetector-row CT (MDCT) play an important role in diagnosis of retroperitoneal emergencies, providing useful informations on the type, site, extent and management of the fluid collections. An accurate CT assessment requires the awareness of the existence of dissectable retroperitoneal fascial planes.

Does gender influence outcome of AAA endoluminal repair?

Background: It has been suggested that female patients have a less favourable outcome of endoluminal repair of abdominal aortic aneurysms. Yet, data on stratified per gender are lacking.

Methods: We reviewed our prospective database of 402 endografts over a 4-year period and the peri- and postoperative course in the 25 (6%) female patients was compared with the 377 (94%) male patients.

Outcome of abdominal aortic endografting in high-risk patients: a 4-year single-center study.

Purpose: To evaluate feasibility, safety, and effectiveness of endovascular abdominal aortic aneurysm (AAA) repair in patients whose fitness for surgery is questionable.

Methods: Between April 1997 and December 2001, 389 consecutive patients underwent endovascular AAA repair. Of these, 51 (13.

Device migration after endoluminal abdominal aortic aneurysm repair: analysis of 113 cases with a minimum follow-up period of 2 years.

Purpose: Device migration (DM) has been shown to cause late failure after endoluminal abdominal aortic aneurysm (AAA) repair. To establish the incidence rate and the predictive factors of distal migration of the proximal portion of the endograft, computed tomographic (CT) scans performed at different time intervals during follow-up examination of 113 patients were reviewed.

Patients And Methods: Between April 1997 and March 1999, 148 patients underwent endoluminal AAA repair with a modular endograft with infrarenal fixation (Medtronic-AVE AneuRx, Santa Rosa, Calif) at our unit.

Chronic iliac artery occlusion: treatment with the Strecker stent after PTA.

The purpose of this retrospective study was to evaluate the use of percutaneous transluminal angioplasty (PTA) and subsequent. Strecker stent implantation for the treatment of chronic iliac artery occlusions. A total of 39 patients were subjected to this procedure.

Percutaneous transluminal angioplasty in the treatment of chronic mesenteric ischemia: results and 3 years of follow-up in 23 patients.

Background: We evaluated the clinical efficacy of visceral angioplasty in the treatment of chronic mesenteric ischemia.

Methods: Over a 14-year period, we performed percutaneous transluminal angioplasty of 41 occlusive diseases of visceral arteries founded by angiography in 23 patients with chronic mesenteric ischemia. All but one (fibrodysplasic) stenoses were atherosclerotic, and 13 were localized in the ostial tract.
