Detection of liver metastases in cancer patients with geographic fatty infiltration of the liver: the added value of contrast-enhanced sonography
Purpose The aim of this study is to assess the role of contrast-enhanced ultrasonography (CEUS) in the detection of liver metastases in cancer patients with geographic liver fatty deposition on greyscale ultrasonography (US). Methods Thirty-seven consecutive cancer patients (24 women and 13 men; age, 33 to 80 years; mean, 58.1 years) with geographic liver fatty deposition, but without any detectable focal liver lesion on greyscale US, underwent sulphur hexafluoride-enhanced US. Two readers reported by consensus the presence, size, and location of any detected lesion. All patients underwent magnetic resonance imaging (MRI) as a confirmatory study. Sensitivity, specificity, positive and negat…
CARATTERISTICHE NEURORADIOLOGICHE DI UN CASO DI SCLEROSI TUBEROSA DIAGNOSTICATO IN ETÀ ADULTA
SCOPO DEL LAVORO: presentiamo un caso di Sclerosi Tuberosa (Tuberous sclerosis complex, TSC; anche nota come Sindrome di Bourneville-Pringle) diagnosticato tardivamente grazie al sospetto posto dalle indagini neuroradiologiche eseguite in una paziente di 40 anni con in anamnesi ritardo mentale, crisi epilettiche e disturbi del visus.MATERIALI E METODI: la paziente si presenza alla nostra attenzione per un episodio di disorientamento e confusione mentale; dopo una prima valutazione in PS veniva eseguita una TC dell’encefalo in tecnica sequenziale (Siemens SOMATON AS+, 128 strati) e trasferita presso l’U.O.C. di Neurologia. In seguito, per una migliore caratterizzazione dei reperti descritti …
Value of serial magnetic resonance imaging in the assessment of brain metastases volume control during stereotactic radiosurgery
AIM To evaluate brain metastases volume control capabilities of stereotactic radiosurgery (SRS) through serial magnetic resonance (MR) imaging follow-up. METHODS MR examinations of 54 brain metastases in 31 patients before and after SRS were reviewed. Patients were included in this study if they had a pre-treatment MR examination and serial follow-up MR examinations at 6 wk, 9 wk, 12 wk, and 12 mo after SRS. The metastasis volume change was categorized at each follow-up as increased (> 20% of the initial volume), stable (± 20% of the initial volume) or decreased (< 20% of the initial volume). RESULTS A local tumor control with a significant (P < 0.05) volume decrease was observed in 25 meta…
Magnetic resonance imaging in the assessment of brain involvement in alcoholic and nonalcoholic Wernicke's encephalopathy
AIM To present the typical and atypical magnetic resonance (MR) imaging findings of alcoholic and non-alcoholic Wernicke’s encephalopathy. METHODS This study included 7 patients with Wernicke’s encephalopathy (2 men, 5 women; mean age, 52.3 years) that underwent brain MR examination between January 2012 and March 2016 in a single institution. Three patients were alcoholics and 4 patients were non-alcoholics. MR protocol included a T2-weighted sequence, a fluid attenuation inversion recovery (FLAIR) sequence, a diffusion-weighted sequence (b = 0 and 1000 s/mm2), and a contrast-enhanced MR sequence. All MR images were retrospectively reviewed at baseline and follow-up by two radiologists. RES…
