Summary Background: Vascular anomalies are usually diagnosed through their clinical picture and history. The purpose of this study was to assess the role of MR imaging in initial assessment of cervicofacial vascular anomalies in children. Material/Methods: Twenty pediatric patients with vascular anomalies located in the cervicofacial region underwent MRI examination in our department. Images were evaluated for lesion detectability and its signal characteristics (on T1w, T2w images with fat suppression and contrast enhanced T1w sequences); the extent of the lesions and surrounding tissue involvement were also assessed. Results: In the studied group MR images revealed all anomalies and provided information of their anatomic extent and invasion of surrounding anatomic structures. Nine hemangiomas and six venous malformations were found among studied patients. Two children had multiloculated lesions corresponding to lymphatic malformations. One examination visualized a lesion consisting mainly of dilated vascular channels with an apparent feeding artery, which was consistent with arteriovenous malformation. Two remaining lesions were mixed malformations. Nine patients had lesions limited to subcutaneous tissue. Two masses infiltrated bone structures. There was muscle involvement found in nine cases. Conclusions: MR imaging is a well-established method for detection and monitoring of vascular anomalies in children. With ultrasound used mostly for initial diagnosis and additional flow assessment, angiography viewed as an invasive therapeutic method and computed tomography used only in specific situations due to its high irradiation dose, magnetic resonance is the best imaging method used in differential diagnosis and topographical characterization of vascular malformations and tumors of cervicofacial area in pediatric patients. Noninvasively and without irradiation, it enables evaluation of the extent and characteristics of lesions and planning proper therapeutic strategy.

One of the most serious postoperative complications are the renal artery (...

Summary Background: Sarcoidosis is a multisystemic granulomatous disease of unknown etiology that predominantly affects lungs and intrathoracic lymph nodes; in rare cases (approx. 10%), infiltration of the spleen and liver may be observed. In order to identify hepatosplenic infiltration, MRI/CT of the abdomen and different ultrasound techniques (PD US, US D) are usually performed. Contrast enhanced ultrasound (CEUS) is a new technique in this diagnostic algorithm, but the fact that this is a safe, accurate, and widely available method opens a new perspective for the detection of abdominal lesions in sarcoidosis. Case Reports: We report 2 cases of hepatosplenic sarcoidosis – a 41-year-old woman with splenic lesions and a 46-year-old man with liver infiltration. Results: On the basis of these 2 cases we intended to show the diagnostic potential of contrast enhanced ultrasound for the recognition of focal lesions of the spleen and liver in patients suffering from sarcoidosis.

Purpose Methods and Materials Results Conclusion References Personal Information, Purpose: In case of the evaluation of organs with a rich vascularization, contrast enhanced ultrasound (CE-US) allows for the separation of areas with reduced or absent microcirculation. A major advantage of this method is the ability to quantify tissue...
