Concomitant use of transvaginal sonography and Doppler indices improve diagnosis of adenomyosis.

This study was planned to investigate whether measuring of Doppler indices with TV-DUS improved the diagnosis of adenomyosis. Preoperative Doppler indices of subjects with a preliminary diagnosis of adenomyosis were compared with the histopathological results of excised specimens. Sensitivity, specificity and positive/negative predictive values (PPV, NPV) of the measured indices were also calculated. Sensitivity, specificity, PPV and NPV and positive and negative likelihood ratios (LR+) and (LR-) of TV-US in the diagnosis of adenomyosis were found to be 70.8%, 62.1%, 40.4%, 85.4%, 1.96 and 0.47, respectively. Sensitivity, specificity, PPV, NPV, LR + and LR - in the diagnosis of adenomyosis following the addition of TV-DUS were found to be 90%, 94.2%, 81.8%, 97%, 15.5 and 0.10, respectively. Concomitant use of TV-US and TV-DUS improved correct diagnosis of adenomyosis with high sensitivity.

Investigating the relationship between persistent reflux flow on the first postoperative day and recurrent varicocele in varicocelectomy patients.

BACKGROUND: The aim of this study was to investigate the presence of persistent reflux flow on the first postoperative day using color Doppler sonography (CDS) in patients who had undergone sub-inguinal varicocelectomy, and to research the relationship between persistent reflux flow and recurrent varicocele. METHODS: A total of 54 patients were included in the study. Ages of the patients were between 21 and 38 years (mean 27.3 ± 7.6). All patients were evaluated four times with CDS: preoperatively, first postoperative day, 3 months postoperative, and finally 6 months after the operation. RESULTS: Preoperative venous diameters were measured between 3 and 5.5 mm; mean vein diameters were 3.8 ± 0.7 mm for the left side and 3.4 ± 0.4 mm for the right side. Mean duration of reflux was 3.5 ± 0.3 seconds on the left side and 2.9 ± 0.7 seconds on the right side. First postoperative day persistent Valsalva-induced reflux flow was seen in 10 patients (18%). Mean venous diameter was measured 1.8 ± 0.9 mm. Three months after the operation, Valsalva-induced reflux flow was seen in two patients (3%) in whom reflux was not seen on the first postoperative day. After 6 months, venous diameters larger than 2 mm at rest and the occurrence of reflux during the Valsalva maneuver were considered to be a recurrence. Six months after the operation, 12 patients had recurrent varicocele. Detecting persistent reflux with CDS on the first postoperative day was found to be 85% sensitive and 100% specific for showing recurrence. CONCLUSION: Valsalva-induced persistent reflux flow investigated with CDS on the first postoperative day can be used to show success of the surgery and is also an indicator of recurrence in varicocelectomy patients.

Intrauterine temporomandibular joint dislocation: prenatal sonographic evaluation.

Congenital temporomandibular joint (TMJ) diseases are very rare disorders and are usually diagnosed in childhood. Developmental disorders of the TMJ such as hypoplasia, hyperplasia, and aplasia of the TMJ compartments are characterized by TMJ dysfunction. In childhood, these patients experience recurrent dislocation, pain, and malocclusion. We present the case of a 25-week fetus with unilateral TMJ dislocation with fluid retention in the joint diagnosed by ultrasonography. To the best of our knowledge, this is the first case of TMJ dislocation diagnosed by ultrasonographic evaluation during the prenatal period.

Coexistence of a congenital arteriovenous fistula of the left breast with a true aneurysm of the right internal mammary artery.

Arteriovenous fistulas (AVF) and true aneurysms are uncommon arterial vascular disorders of the breast. The etiology can be either acquired or congenital. Coexistence of a congenital AVF and true aneurysm of internal mammary artery (IMA) branches is a very rare condition. We present a case of congenital AVF and true aneurysm of the IMA in a woman, age 56 years. To the best of our knowledge, this is the first published case of the coexistence of a congenital AVF with a true aneurysm of the breast. The radiologic findings of these rare entities have been reviewed according to the literature.

Primary ovarian and pararectal hydatid cysts mimicking pelvic endometriosis.

We report a case of 48-year-old woman with multiple hydatid cysts in pararectal region and right paraovarian localization with an unusual sonographic and computed tomographic presentation mimicking a pelvic endometriosis. During laparotomy, multiple pararectal and right ovarian cysts resembling endometriosis were resected. Pathologic examination gives the diagnosis of hydatid cysts. Retrospectively, we investigate the primary infection but the patient had no history of hepatic and liver involvement, it is a case of primary infection.

Contrast media-enhanced power Doppler sonography for evaluation of hemangiomas and malignant tumors in the liver.

AIM: To evaluate the characterization of liver hemangiomas and malignant tumors using power Doppler sonography before and after intravenous injection of a sonocontrast agent. METHODS: Forty-five patients with 57 liver tumors (22 hemangiomas, 24 metastases, 10 hepatocellular carcinomas (HCC) and one cholangiocellular carcinoma) were examined prospectively. The distribution (peripheral, central, mosaic) and extent (none, minimal, moderate and strong) of intratumoral flow pattern in each sonographic examination was subjectively classified. RESULTS: The administration of the sonocontrast agent by bolus injection caused enhancement to gradually increase up to 2 min and lasted for 4-5 min. After injection of contrast agent, flow signals appeared or increased in 34 tumors. No signal enhancement was observed in 18 hemangiomas, four metastases and one HCC. The sensitivity and specificity of intratumoral vascularity for the detection of malignant liver tumors was 37.1 and 90.9% for unenhanced power Doppler sonography, and 85.7 and 81.8% for contrast-enhanced power Doppler sonography, respectively. CONCLUSION: Contrast-enhanced power Doppler sonography is superior to unenhanced power Doppler sonography in the demonstration of malignant tumor vascularity, and is helpful in differentiating between hemangiomas and malignant liver tumors. A specific flow pattern within the tumor is not established in primary and metastatic malignant tumors with contrast-enhanced power Doppler sonography.
