Incidentally Discovered Hepatic Lesions
Historically, unsuspected incidental solid tumors of the liver were encountered only at the time of laparotomy when biopsy and definitive histologic diagnosis were obtainable. However, as cross-sectional imaging studies have become widely available and increasingly applied, the identification of unsuspected liver lesions has become common, and the appropriate means to address these lesions is a...
متن کاملFocal Hepatic Lesions: Evaluation with Contrast-Enhanced Gray-Scale Harmonic US
OBJECTIVE To determine the findings of various focal hepatic lesions at contrast-enhanced gray-scale ultrasound (US) using a coded harmonic angio (CHA) technique and emphasizing lesion characterization. MATERIALS AND METHODS The study involved 95 patients with 105 focal hepatic lesions, namely 51 hepatocellular carcinomas (HCCs), 22 metastases, 22 hemangiomas, four cases of focal nodular hype...
متن کاملEffects of Gray-Scale Ultrasonography Immediate Post-Contrast on Characterization of Focal Liver Lesions
This study compared the imaging features of conventional gray scale ultrasound (US) before and after contrast-enhanced ultrasound (CEUS) for focal liver lesions and 22 evaluated the role of US post-CEUS in characterizing liver lesions. 126 patients with 158 focal liver lesions underwent CEUS and US post-CEUS examination and entered this study. There were 74 hepatocellular carcinomas (HCC), 43 h...
متن کاملIndeterminate liver lesions in cancer
It is important to distinguish liver metastases from incidental benign liver lesions which may be present in patients with cancer. In a minority of cases, sonography or CT may be sufficient to characterise benign lesions, but the range of sequences and contrast media available for liver MRI provides the opportunity for more specific diagnosis in the great majority of cases. Biopsy is rarely nee...
متن کاملIncidentally Discovered Adrenal Schwannoma
Schwannoma is a rare tumor of neural crest cell origin that is rarely seen arising from the adrenal gland. We report a case of an adrenal mass discovered incidentally in a 70-year-old man as part of a hematuria workup. Metabolic evaluation was unremarkable, and imaging studies did not meet strict imaging criteria for a typical adenoma. Following surgical excision and pathologic evaluation with ...
