2018 Journal of Renal and Hepatic Disorders  
Angiomyolipoma is a type of benign renal tumor. It is sporadic and isolated in 80% of cases. The remaining 20% is associated with tuberous sclerosis complex or pulmonary lymphangioleiomyomatosis. Generally, angiomyolipomas manifest themselves as angiomyolipomatosis, in which the angiomyolipomas are larger, bilateral, and widespread. Understanding whether angiomyolipomas are present in the context of angiomyolipomatosis is of considerable importance because it might be associated with malignant

2016 Journal of Kidney Cancer and VHL  
<p>Blepharoptosis is the drooping or inferior displacement of the upper eyelid. Blepharoptosis can be either congenital or acquired. Tumour metastasis is one of the acquired causes of blepharoptosis. The lungs, locoregional lymph nodes, bone and liver are the usual sites of metastases of renal cell carcinoma (RCC); however, unusual locations of RCC have also been reported. Herein, we describe a case of a 47-year-old man with unilateral ptosis and blurred vision due to metastatic RCC. We

2017 Journal of Kidney Cancer and VHL  
<p>Cystic nephroma is a rare, benign multicystic lesion of the kidney. This tumor occurs both in children and in adults. In children, it is highly prevalent in males; in adults, it is more frequent in women. The term "cystic nephroma" represents two apparently different entities: pediatric cystic nephroma, a benign form thought to originate from metanephric tissue, and adult cystic nephroma, considered as a lesion of mixed epithelial stromal tumor. The clinical presentation may be a palpable

Portomesenteric Venous System Gas after CT Colonography: A Case Report

Ilaria Sansoni, Claudia Lucia Piccolo, Ilenia Di Giampietro, Matteo Polacco, Bruno Beomonte Zobel
2012 Case Reports in Radiology  
Portomesenteric vein gas can occur owing to a variety of interraleted factors such as loss of mucosal integrity and intraluminal overpressure, and the most common and serious cause is bowel ischemia, which requires urgent laparotomy. Nevertheless, when portal venous gas is caused by nonischemic causes, surgery is not required and it can be treated conservatively. So, its features should be carefully evaluated at CT scan, together with clinical findings. The authors report a case of an old male

2008 Journal of thoracic imaging  
We report the case of a young man, affected by rheumatoid arthritis who developed a rapid-onset shortof-breath, hemoptysis, and severe weakness, about 2 weeks after the administration of leflunomide. Chest radiography showed central bilateral opacities and pleural effusion as confirmed by the high-resolution computed tomography that demonstrated diffuse ground-glass and interlobular septal thickening as well. On admission at the Emergency Department, a microhematuria and a severe anemia were

On the basis of the clinico-radiologic presentation, a pulmonary hemorrhage was likely to occur; so to clarify the origin of this process, a complete serologic examination was performed but all the antibodies were negative. Finally a renal biopsy was performed and it showed a pauci-immunologic glomerulonephritis and the bronchioloalveolar lavage confirmed the diffuse alveolar hemorrhage. In conclusion, the diagnosis of leflunomide-pulmonary-renal syndrome was rendered. The treatment with leflunomide was suspended; the conditions of the patient gradually improved and he became completely asymptomatic 1 week later.

2018 Shanghai Chest  
Lung cancer is a malignant tumor with high lethality, responsible for about 28% of all cancer deaths. In this study, using a quantitative CT imaging-based approach, we aimed to investigate the differences of abdominal adipose tissue distribution in patients with non-small cell lung cancer (NSCLC) according to gender. Methods: A group of 66 patients with NSCLC at first diagnosis [male: 45, mean age: 67.3 years (range, 51.0-88.0 years); female: 21, mean age: 62.4 years (range, 44.0-84.0 years)]

As a control group, 70 patients without history of malignancies who have undergone a chest-abdomen CT for pre-operative cardiovascular surgery planning [male: 42, mean age: 62.7 years (range, 40.0-83.0 years); female: 28, mean age: 66.4 years (range, 39.0-83.0 years)] was included. We calculated total adipose area (TAA), visceral adipose area (VAA) and subcutaneous adipose area (SAA) using OsiriX to analyze cross-sectional CT images. The differences were analyzed using the Student's t-test (P<0.05). The Pearson's correlation coefficient (r) and the significance of the simple regressions (ρ) were calculated. Results: In the female group, the visceral/subcutaneous (V/S) ratio was higher in the control group than in patients. Conversely, in the male group we found a higher V/S ratio in patients then controls. Considering male and female together, the age parameter showed a significant positive correlation with the amount of visceral (r=0.390; P=0.001) and total (r=0.270; P=0.030) fat in the patients. Dividing the groups between male and female, the age parameter showed a significant positive correlation with the amount of visceral fat in the female patients (r=0.440; P=0.049), visceral fat in the male patients (r=0.320; P=0.030), subcutaneous fat in the female patients (r=0.480; P=0.030) and total fat in the female patients (r=0.490; P=0.020). Conclusions: The results of this study are in line with the concept of differential gender-based relationships among abdominal fat distribution, age and NSCLC.

2021 Journal of Kidney Cancer and VHL  
Development of more sensitive imaging techniques has caused an increase in the number of diagnosed small renal tumors. Approximately 2–3% of these lesions are proved to be angiomyolipomas (AML), a rare benign tumor of the kidney sometimes causing pain and hematuria. The most required approach is observation, but in the case of recurrent symptoms or larger tumors, which may cause bleeding, a more active treatment is required. We present two cases of symptomatic AML tumors of different sizes in

The lesions were diagnosed on the basis of contrast-enhanced computed tomography (CT) scan and magnetic resonance imaging (MRI). Both treatments proved to be effective and safe for treating renal AMLs. A follow-up carried out, based on contrast-enhanced CT scan, confirmed complete treatment of AML and decreased lesion size. There are myriad minimally invasive approaches for the treatment of renal AMLs, and the preservation of renal function remains a priority. The most popular treatment option is the selective renal artery embolization. Owing to its limited invasiveness, CRA could be an attractive option for the preventive treatment of AML.

2011 Journal of Medical Case Reports  
Several adverse events have been associated with the use of bevacizumab during the treatment of neoplasms such as colorectal cancer, breast cancer, non-small cell lung cancer, pancreatic cancer and renal cell carcinoma. The present case demonstrates how focal neurological symptoms lead to the magnetic resonance imaging-based differential diagnosis between focal parenchymal metastases and microischemic phenomena, with crucial implications for patient management. Case presentation: We describe

Brain magnetic resonance imaging examination revealed millimetric lesions with restricted diffusion without perilesional edema or contrast enhancement after gadodiamide intravenous injection, suggestive of acute microischemic phenomena. This complication is very rare but clinically significant. Conclusion: The differential diagnosis in patients with cancer undergoing bevacizumab treatment should include microischemic phenomena.

Assessing pressure ulcers (PUs) in early stages allows patients to receive safer treatment. Up to now, in addition to clinical evaluation, ultrasonography seems to be the most suitable technique to achieve this goal. Several treatments are applied to prevent ulcer progression but none of them is totally effective. Furthermore, the in-depth knowledge of fat regenerative properties has led to a wide use of it. With this study the authors aim at introducing a new approach to cure and prevent the

Values of skin thickness, fascial integrity, and subcutaneous vascularity were recorded both on the PU area and the healthy trochanteric one, used as control region. Fat grafting was performed on all patients. At three months, abnormal ultrasonographic findings, such as reduction of cutaneous and subcutaneous thickness, discontinuous fascia, and decrease in subcutaneous vascularity, all were modified with respect to almost all the corresponding parameters of the control region. Results highlight that the use of fat grafts proved to be an effective treatment for early-stage PUs, especially in the care of neurological and chronic bedridden patients.
