Inflammatory pseudotumor (IPT) is a quasineoplastic lesion that most commonly involves the lung and the orbit; kidney involvement is rare. We report a case of inflammatory pseudotumor of the kidney. The patient was a 61-year-old man who presented with no symptoms. Nonenhanced computed tomography (CT) demonstrated an ill-defined, isodensity mass measuring 3.5 cm in the lower portion of the left kidney. Contrast-enhanced CT showed that branches of the renal artery without encasement penetrated the tumor; there was a little enhancement in the mass on the arterial phase and homogeneous enhancement on the venous phase. On magnetic resonance imaging the mass showed intermediate signal intensity on T1-weighted images (T1WIs) and low signal intensity on T2WIs. Most IPTs of the kidney appear as an ill-defined, hypovascular, homogeneous tumor on CT images, with variable signal intensity on MRI T1WIs and low signal intensity on T2WIs. Our case had the same imaging findings, with branches of the renal artery penetrating the tumor. If the renal tumor has these radiological findings, the tumor may be IPT.
Background: There is no definite consensus regarding the management of symptomatic isolated celiac artery dissection (ICAD), and the effect of conservative medical treatment has never been evaluated.
Methods and Results:We enrolled 13 consecutive symptomatic ICAD patients without signs of arterial rupture between 2006 and 2015. All patients received noninvasive conservative medical treatment. The epidemiology, radiological findings and prognostic effect of conservative medical treatment on outcomes were retrospectively assessed. ICAD usually developed in middle-aged men around 50 years old who had a history of smoking. The patients typically presented with acute continuous epigastric pain at rest and with abdominal tenderness on physical examination. On enhanced computed tomography at presentation, the false lumen was found to be double-barreled in 2 patients (15.4%), partially thrombosed in 1 (7.7%), and completely thrombosed in 10 (76.9%). Dissection of associated branches was found in the left gastric artery in 1 patient (7.7%), common hepatic artery in 5 (38.5%), and splenic artery in 7 patients (53.8%). Malperfusion was not found in the stomach or liver but was found in the spleen in 4 patients (30.8%). During a median follow-up period of 376 (165-602) days, all patients were alive without any antiplatelet, anticoagulant, endovascular or surgical treatment.Conclusions: Symptomatic ICAD without arterial rupture can be safely treated with conservative medical therapy over the short term.

With the lateral approach, it is possible to use 11G probes if the breast is thin (in our study minimum thickness was 10 mm) with only polyethylene foam. We believe this to be an advantage of the lateral approach. This advantage is very important in stereotactic biopsy, especially in Japan, as Japanese women's breasts are generally thinner than most Western women's.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
