ABSTRACT: To compare the results of pathologic and cytologic reports of specimens acquired from focal liver lesions using ultrasound-guided biopsy and to evaluate the necessity of performing both techniques in the same patient.
21 patients were eligible for enrollment in the study. Specimens for both pathologic and cytologic examination were obtained from 16 lesions using a 17G needle guide in a single puncture attempt. In 2 cases the diagnosis was based on cytologic smears. In 3 cases only histologic sections were acquired. The needle was introduced under continuous ultrasonographic control using a freehand technique. A cytologist was present at all times.
The diagnostic sensitivity of cytologic examination was 83.33% and that of histologic examination was 94.74%. Histology diagnosed all cases of benign lesions and was proved inconclusive in 1 patient. The diagnostic sensitivity and accuracy of both methods combined reached 100%. In 94.4% malignancy was immediately diagnosed by cytology.
Combination of both methods should increase the sensitivity and accuracy in diagnosing focal liver lesions performing a safe minimally invasive technique.

ABSTRACT: Renal artery stenosis (RAS) is the most common underlying medical condition in secondary hypertension among adults, representing about 5% of all cases of hypertension. Early diagnosis of RAS is an important clinical objective since interventional therapy may improve or cure hypertension and preserve renal function. Contrast angiography is the currently reference standard for the diagnosis of RAS; however, its invasive nature renders it unsuitable for screening purposes. Among screening tests used for the detection of RAS (computed tomography angiography, magnetic resonance angiography, radionuclide scanning), multiple studies have shown that color Doppler ultrasound (CDUS), although highly operator-dependent, can be an effective tool in the diagnosis of RAS. CDUS imaging is a simple, safe (noninvasive) and widely available technique; in addition, the procedure is painless and well tolerated by patients. In this concrete review we will underline the established color Doppler ultrasound criteria used for the detection of RAS, highlight their limitations and see how their combination may improve the diagnostic accuracy of this method.

ABSTRACT: We reported the case of an adult male with an extratesticular mass prove to be postoperative a chronic inflammatory process. The importance of B-mode and color Doppler sonography in the differential diagnosis and literature regarding epididymal nodules and tumors of the paratesticular structures (epididymis) is reviewed and discussed.

ABSTRACT: An umbilical metastatic lesion is called 'Sister Mary Joseph's nodule'. It is an uncommon clinical or radiographic finding, and it is rare as the first sign of a malignant disease.
We report three cases of Sister Mary Joseph's nodule. In the three cases presented, the primary tumor was an adenocarcinona of the sigmoid colon, a carcinoma of the bladder, and an adenocarcinoma of the gallbladder, respectively.
The differential diagnosis of an umbilical lesion should always include metastatic disease apart from benign lesions and primary neoplasms.
