Hepatic toxocariasis: US, CT and MRI findings.

Visceral larva migrans (VLM) most commonly occurs as a febrile disease of childhood particularly affecting children between 1 and 7 years of age. Pulmonary, dermatological, hepatic, lymphatic, cardiac, rheumatological and neurological manifestations may occur. VLM seems to be a rare disease in adults. We report the imaging findings of a woman with hepatic toxocariasis. Ultrasonography showed a solitary hepatic lesion measuring 4 x 3 cm, displaying a hypoechoic-heterogeneous pattern with ill-defined borders and distal acoustic enhancement, located in the right sub-diaphragmatic area. Two enlarged periportal lymph nodes and moderately dilated intrahepatic biliary ducts were also noted. The probability of toxocariasis was discussed, based on sonographic and biopsy findings, and the final diagnosis was confirmed by a specific ELISA test. In summary, a clinical picture of cholestasis initially resembling hepatitis or malignancy should be further evaluated by imaging techniques, and the ultrasound examiner should be familiar with the possible findings of hepatic toxocariasis, which consist of focal ill-defined hepatic lesions, hepato-splenomegaly, biliary dilatation, sludge and periportal lymph node enlargement.

Human fascioliasis.

Fasciola hepatica, a zoonotic liver fluke, can also cause disease in humans. Common symptoms are epigastric pain, upper abdominal pain and malaise. Fever and arthralgia are common in acute fascioliasis. Eosinophilia is the predominant laboratory finding, especially in patients with the acute form of the disease. Diagnosis and treatment is not easy, as physicians rarely encounter this disease, and effective drugs are not available in many countries. Human fascioliasis may be underestimated. Patients with eosinophilia and abdominal pain should be evaluated for F. hepatica infestation by parasitological, radiological and serological tests.

Ultrasound-guided percutaneous sclerotherapy of hydatid liver cysts in children.

To evaluate the efficacy of ultrasound (US) guided percutaneous sclerotherapy in the pediatric population, 14 hydatid liver cysts (HLC) in eight male patients whose ages ranged between 6 and 16 years (mean 9.9 years) were treated. The maximum diameter was 110 mm. Albendazole was administered orally to all patients for 1 week before percutaneous treatment and for 3-6 months after the procedure to prevent dissemination of the disease. Cyst puncture was performed with 20 G Chiba needles using US guidance. More than one-half of the estimated cyst volume was aspirated, then 20% hypertonic saline (7 cysts) or sterile 96% alcohol (7 cysts) equivalent to one-third of the estimated cyst volume was injected into the cavity and left for 5-15 min. Finally, all the fluid in the cavity was reaspirated. Catheterization was not performed. Follow-up US examinations were performed every month during the first 6 months and every 3 months thereafter. The follow-up period ranged between 6 and 51 months (mean 15 months). No major complications were seen during or after the procedures. Two cysts in two patients completely disappeared. Volumes of the 11 cysts in five patients who were followed for 6-21 months were markedly reduced (22%-64% of the initial volume) and thick septations and solid debris-like structures were seen within the cyst cavities. There was no significant change in 1 cyst. US-guided percutaneous sclerotherapy is thus a safe and effective treatment of HLC in children.

Orbital Doppler sonography findings in cases of brain death.

In this study, we investigated the blood flow velocity changes in orbital arteries by using Doppler sonography in eight patients with brain death. Peak-systolic and end-diastolic velocities and resistive indices of the ophthalmic and central retinal arteries were evaluated. We observed the absence or reversal of end-diastolic blood flow in these arteries. To our knowledge, this finding has not been previously reported to be associated with brain death.

Renal colic: comparison of spiral CT, US and IVU in the detection of ureteral calculi.

The aim of our study was to compare non-contrast spiral CT, US and intravenous urography (IVU) in the evaluation of patients with renal colic for the diagnosis of ureteral calculi. During a period of 17 months, 112 patients with renal colic were examined with spiral CT, US and IVU. Fifteen patients were lost to follow-up and excluded. The remaining 97 patients were defined to be either true positive or negative for ureterolithiasis based on the follow-up data. Sensitivity, specificity, positive and negative predictive value and accuracy of spiral CT, US and IVU were determined, and secondary signs of ureteral stones and other pathologies causing renal colic detected with these modalities were noted. Of 97 patients, 64 were confirmed to have ureteral calculi based on stone recovery or urological interventions. Thirty-three patients were proved not to have ureteral calculi based on failure to recover a stone and diagnoses unrelated to ureterolithiasis. Spiral CT was found to be the best modality for depicting ureteral stones with a sensitivity of 94 % and a specificity of 97 %. For US and IVU, these figures were 19, 97, 52, and 94 %, respectively. Spiral CT is superior to US and IVU in the demonstration of ureteral calculi in patients with renal colic, but because of its high cost, higher radiation dose and high workload, it should be reserved for cases where US and IVU do not show the cause of symptoms.

Percutaneous sclerotherapy of a symptomatic simple renal cyst in a child: observation of membrane detachment sign.

A 6-year-old girl with a symptomatic renal cyst underwent successful percutaneous aspiration and sclerotherapy with hypertonic saline under US guidance. Although membrane detachment sign was seen clearly during aspiration, it was confirmed to be a simple cyst. In contrast to previous reports, membrane detachment sign is not pathognomonic for hydatid cysts and may be seen after simple cyst aspiration. Therefore, differentiation of a symptomatic renal cyst from a hydatid cyst should not depend solely on membrane detachment sign. In either case US- or CT-guided percutaneous sclerotherapy should always be considered before surgery.

Fascioliasis: US, CT, and MRI findings with new observations.

BACKGROUND: The purpose of this study is to describe the ultrasonographic (US), computed tomographic (CT), and magnetic resonance imaging (MRI) findings in fascioliasis and to emphasize the impact of radiology in diagnosis. METHODS: Radiologic findings in 23 consecutive patients with fascioliasis were prospectively recorded. All patients had at least one US and CT examination, and 10 of them were studied by MRI. All diagnoses were confirmed by serologic methods. In the first three cases, initial diagnosis was reached by microscopic demonstration of the parasites' eggs in bile obtained by US-guided gallbladder aspiration. RESULTS: In the hepatic phase of fascioliasis, multiple, confluent, linear, tractlike, hypodense, nonenhancing hepatic lesions were detected by CT. On US, the parasites could be clearly identified in the gallbladder or common bile duct as floating and nonshadowing echogenic particles. MRI showed the lesions as hypo- or isointense on T1-weighted images and as hyperintense on T2-weighted images. CONCLUSIONS: CT findings in the hepatic phase and US findings in the biliary phase are characteristic of fascioliasis. Because clinical and laboratory findings of fascioliasis may easily be confused with several diseases, radiologists should be familiar with the specific radiologic findings of the disease to shorten the usual long-lasting diagnostic process.

Acute colonic obstruction caused by intussusception and extrusion of a sigmoid lipoma through the anus after barium enema.

Colonic lipomas are often asymptomatic, but large lipomas may produce abdominal pain, diarrhea, constipation, hemorrhage, and intussusception. We report a young woman with a colonic lipoma who presented as an acute abdominal emergency with total colonic obstruction and severe pain associated with intussusception and extrusion of the tumor through the anus. The case was interesting because of its presentation after a double-contrast barium enema and because of the patient's young age and the tumor's location on the left side of the colon.
