Comparative Study
Intraoperative sonography in patients with colorectal cancer and resectable liver metastases on preoperative FDG-PET-CT.
Combined fluorine 18-fluorodeoxyglucose-positron emission tomography-CT imaging has been shown to be of good diagnostic value in the preoperative evaluation of patients with colorectal cancer and liver metastases. The adjunctive use of intraoperative sonography (IOUS) may have a limited impact on treatment selection in these patients. ⋯ In patients with colorectal carcinoma and potentially resectable liver metastases on preoperative PET-CT, IOUS can provide additional information that may alter decision making with regard to surgical technique.

Case Reports
Sonographic diagnosis of uncomplicated first-trimester pregnancy in the rudimentary horn of a unicornuate uterus.
Although pregnancy in a rudimentary uterine horn is rare, the correct diagnosis of this condition on routine sonographic examination is critical, because its natural history usually involves the rupture of the pregnant horn during the second or third trimester, resulting in life-threatening bleeding. We report a case in which the diagnosis of right unicornuate uterus with a left noncommunicating rudimentary horn was made in the first trimester on routine sonographic examination.

We report a case of phlegmonous gastritis in a 36-year-old man presenting with anorexia, epigastralgia, and high fever. Endoscopy showed an edematous lesion suggesting a submucosal lesion. Endosonography revealed thickening of the gastric wall, mainly involving the submucosa, with a few anechoic areas. ⋯ The patient was treated with antibiotics and endoscopic mucosal resection. Culture of the aspirated pus from the lesion revealed Streptococcus pyogenes. Follow-up endosonography performed 1 week later showed significant improvement.

Case Reports
Spontaneous rupture with pseudoaneurysm formation in a nodular goiter presenting as a large neck mass.
Acute airway obstruction caused by goiter hemorrhage is a rare but potentially life-threatening condition. We report a case of nodular goiter in which spontaneous rupture with active bleeding developed suddenly, presenting as a large neck mass with dyspnea. Sonographic examination revealed a large inhomogeneous soft tissue mass in the left thyroid lobe containing some hypoechoic areas. Color Doppler and spectral Doppler analysis were consistent with a large hematoma and pseudoaneurysm, which was subsequently confirmed at surgery.

Case Reports
Splenic focal lesions as manifestation of sarcoidosis: Characterization with contrast-enhanced sonography.
We report the case of a 74-year-old woman with elevated liver enzyme levels in whom abdominal sonographic examination revealed a diffusely heterogeneous liver parenchyma and multiple hypoechoic subcentimetric splenic nodules. Contrast-enhanced sonography (CEUS) revealed that the splenic focal lesions did not enhance. ⋯ Core biopsy of 1 hepatic nodule revealed noncaseating epithelioid cell granuloma, and the patient was diagnosed with systemic sarcoidosis. CEUS has shown to be useful in the diagnosis of focal hepatic lesions, but studies referring to splenic lesions are lacking.
