Papillary fibroelastomas (PFEs) are one of the most frequent primary cardiac tumors and occur more often in patients with hypertrophic obstructive cardiomyopathy (HOCM). PFEs have been linked to an increased risk of neurological events. We report a case of a 59-year-old woman with HOCM in whom echocardiography (transthoracic and transesophageal, using 2D and 3D techniques) revealed multiple masses in various locations in the left cardiac chambers. Surgical excision of the cardiac tumors and aortic valve replacement was performed and the pathologic report confirmed the diagnosis of PFEs...

AL-amyloidosis is a rare, but complex disease, with a severe prognosis, cardiac involvement being found in half of the patients. The rapid increase of the LV wall thickness predicts an unfavorable evolution. We report the case of a 63-year-old man diagnosed with AL-amyloidosis, with cardiac involvement, associated with multiple site thrombosis.  Specific echocardiographic methods like tissue Doppler imaging and speckle tracking provided crucial diagnostic and prognostic information.

The soleus arcade syndrome is a rare compression neuropathy of the tibial nerve that often remains undiagnosed due to low clinical awareness and difficult diagnosis. We present the case of a female patient admitted with acute worsening of a pre-existing sensory tibial neuropathy and acute tibial nerve palsy after knee joint injection. After a knee magnetic resonance imaging remained non-diagnostic, dynamic ultrasonography was performed. Constriction by the soleus arcade and proximal swelling of the tibial nerve could be demonstrated during plantarflexion of the ankle by means of a dynamic examination in the standing patient...

Cystadenofibromas of the fallopian tubes are very rare benign tumors and very few cases have been reported in the literature worldwide. Usually, the tumor is asymptomatic, and for almost all cases reported, the tumors were incidentally discovered during surgery for other genital pathology. We report the case of a 30-year-old woman with a serous cystadenofibroma of the fallopian tube, presenting with chronic abdominal pain and secondary infertility. The diagnosis of tubal tumor was formulated before surgery and confirmed during laparoscopic surgery...

Psoriatic arthritis is a systemic inflammatory disease in which enthesitis and dactylitis are two of the main hallmarks of the disease. In the last years, ultrasonography is increasingly playing a key role in the diagnosis of psoriatic arthritis and ultrasonography of the entheses, particularly of the lower limbs, is commonly used to assess patients with that disease. New advancements in ultrasound equipment using high frequencies probes allowed us also to identify and characterize the involvementof the entheses of the hand in psoriatic arthritis, confirming the results of the experimental models of the disease and the theory of the sinovial-entheseal complex, even in small joints...

Abdominal wall endometriosis (AWE) is a rare condition defined by the presence of endometrial tissue in the subcutaneous fatty layer and the muscles of the abdominal wall. It is usually caused by the dissemination of endometrial tissue in the wound at the time of obstetrical and gynecological surgeries. AWE is rare and difficult to diagnose. The most frequent clinical presentation is that of a palpable subcutaneous mass near surgical scars associated with cyclic pain and swelling during menses. AWE may be an underreported pathology partly because it has scarcely received attention in the radiologic literature...

The use of grey scale prostate ultrasound decreased after the implementation of magnetic resonance imaging (MRI) for the diagnosis and evaluation of prostate cancer. The new developments, such as multiparametric ultrasound and MRI-ultrasound fusion technology, renewed the interest for this imaging method in the assessment of prostate cancer. The purpose of this paper was to review the current role of prostate ultrasound in the setting of these new applications. A thorough reevaluation of the selection criteria of the patients is required to assess which patients would benefit from multiparametric ultrasound, who wouldbenefit from multiparametric MRI or the combination of both to assist prostate biopsy in order to ensure the balance between overdiagnosis and underdiagnosis of prostate cancer...

Foot orthotics prescription is based on the foot functioning paradigms with tissue stress theory being in avant-garde. The main goal of orthotic therapy is to reduce the internal tissue's pathological stresses in the foot structures. Traditionally, ultrasound scanning technique depicts anatomic related data of both common and uncommon pathology encountered in the clinical practice, helping in diagnosing, treating and evaluating, which are equally important for the practitioners. Its accessibility, compared to biomechanical modelling, makes this technique a valuable tool in the field of foot and ankle disorders...

Contrast-enhanced ultrasound (CEUS) allows a real-time assessment of the vascular pattern of different types of lesions, as it has no renal or liver toxicity, it lacks radiation exposure and it is also cheaper than other imaging methods, having a diagnostic capability that matches contrast-enhanced CT or MRI. In Romania CEUS is used more and more, especially by clinicians, and since some centres have extensive experience in this domain, we felt the need to disseminate our expertise in order to implement this method in as many centres as possible...

AIM: Robotic-assisted thoracic surgery (RATS) has become a promising treatment for pulmonary neoplasms. During RATS, intraoperative ultrasonography can act as an "alternative finger" to "touch" and locate lesions, especially pulmonary nodules. This study was aimed to investigate the efficacy of intraoperative ultrasonographic localization during da Vinci RATS procedures. MATERIAL AND METHODS: Patients with pulmonary nodules were randomly divided into an Experimental Group and Control Group in which nodules were respectively located using intraoperative ultrasonography or by the surgeon's anatomic knowledge...
