New trends in the management of hepatic echinococcus granulosus

The liver is the most commonly involved organ in the body by cystic echinococcosis [CE] secondary to infection with Echinococcus granulosus. In this article, the authors discuss the classification, recent advances in magnetic resonance [MR] imaging for the diagnosis of hepatic CE, and approaches for management of hepatic CE using five therapeutic options that include: antihelminthic chemotherapy, surgery, percutaneous treatment, endoscopic approach, and the "watch and wait" approach

Life threatening liver laceration with arteria; hemorrhage complicating percutaneous treatment of hepatic hydatid cyst

We present a 76-year-old woman known to have a large right hepatic lobe hydatid cyst which recurred twice after surgical excision. CT-guided percutaneous alcohol ablation was conducted to scleroses the cyst, but the procedure was complicated by parenchyma liver laceration and active arterial hemorrhage from a branch of the right hepatic artery. Bleeding was controlled by both endovascular and surgical interventions. Liver laceration with arterial hemorrhage is a rare not previously reported serious complication of percutaneous treatment of hepatic hydatid cyst that may be potentially life-threatening

Current imaging of solid renal masses

More than 40% of solid renal masses are incidentally discovered by ultrasound examinations. Computed tomography [CT] remains the cornerstone investigation for characterization and assessment of the extent of renal tumors, it is complementary to ultrasound. MR imaging is an adjunctive method reserved as a problem-solving technique for indeterminate masses by ultrasound and CT. PET-CT has a great potential role in the staging of renal cancer

Imaging findings of radiation enteritis

In this report the authors describe the imaging features of subacute and chronic radiation enteritis in two patients. Although surgery remains the definitive treatment of complicated chronic radiation enteritis, the potential role of interventional techniques that can be used for management of poor surgical candidates is discussed

Biliary Fascioliasis. case report and review of the literature

Hepatobiliary parasitic diseases are rare in Lebanon. We recently encountered biliary fascioliasis in a Lebanese native. The clinical and laboratory findings were nonspecific. The biliary parasite [Fasciola hepatica] was identified by sonography and confirmed at ERCP that has retrieved the parasite from the common bile duct

Imaging of common benign solid liver tumors

The imaging modalities currently used for radiologic detection and characterization of hepatic neoplasms include color Doppler sonography. helical computed tomography [plain. Diphasic enhanced CT], magnetic resonance imaging [plain, gadolinium enhanced MR] radionuclide scintigraphy [Technetium RBC, sulfur-colloid, IDA scan], angiography, and image-guided percutaneous needle biopsy. MR imaging is probably better at characterizing lesions than CT scan, but the latter remains the modality of choice at many institutions due to the speed of acquisition and good contrast resolution inherent in the technique. Each of these modalities is useful, but accurate lesion detection and specific radiologic diagnosis is most often made in many patients with typical imaging features using a combination of examinations rather than with a single modality. In the remaining patients with atypical features, a definitive diagnosis is usually obtained by a needle biopsy. Table I summarizes the typical clinical and imaging Findings of common benign solid liver tumors, with suggested further work-up and management. Future developments will focus on the use of special contrast agents in sonography and MRI for further evaluation and characterization of focal hepatic lesions. Emerging clinical applications of these special contrast agents have shown a promising future role for contrast in hanced sonography and MRI as problem-solving examinations after inconclusive ultrasound and helical CT
