Patients diagnozed with total placenta previa (n = 40) in whom hysterectomy was performed due to placental adherence defects (n = 20) or in whom the placenta detached spontaneously after a Cesarean delivery (n = 20) were included into the study between June 2008 and January 2011, at the Department of Obstetrics and Gynecology Ege University (lzmir Turkey). Gray-scale US was used to check for any placental lacunae, sub-placental sonolucent spaces or a placental mass invading the vesicouterine plane and bladder Intra-placental lacunar turbulent blood flow and an increase in vascularization in the vesicouterine plane were evaluated with color Doppler mode. Subsequently all patients had MRI and the results were compared with the histopathologic examinations. The sensitivity of MRI for diagnosis of placental adherence defects before the operation was 95%, with...

Although rare, it may occur in any organ or tissue. The most common site is the liver (59-75%), followed in frequency by lung (27%), kidney (3%), bone (1-4%) and brain (1-2%). Other sites such as the heart, spleen, pancreas and muscles are very rarely affected. Unusual sites for this disease can cause diagnostic problems. This pictorial essay illustrates various radiological findings of HD in the liver, spleen, kidney, pancreas, peritoneal cavity, omentum, adrenal, ovary, lung, mediastinum and retroperitoneum. Familiarity with the imaging findings of HD may be helpful in making an accurate diagnosis and preventing potential complications.

DESIGN: A prospective randomized trial. MATERIALS AND METHODS: 35 patients with unexplained infertility undergoing the first IVF treatment were included from June 2004 to December 2005. The diagnosis of UI was based on the following criteria: primary infertility, regular ovulatory cycles, a normal uterine cavity and patent fallopian tubes, no clinical or sonographic evidence of endometriosis, and normal semen parameters. Patients were entered into the study if ten or more cumulus-oocyte-complexs (COCs) were retrieved. The sibling oocytes were randomly divided into conventional IVF or ICSI insemination. The rate of fertilization is expressed as the number of normally fertilized oocytes per number of IVF-or ICSI-treated COCs. Fertilization rate, embryo quality, implantation and pregnancy rates were recorded and compared between groups.

The new developments in imaging modalities have brought improvements in therapeutic aspects. The survival rates in these patients depend on the tumor penetration and the presence of regional lymph node or distant metastasis. The recurrence rates have decreased with the new operation techniques and preoperative radiotherapy, thus increasing the importance of accurate tumor staging. Double contrast barium enema studies enable the diagnosis while staging and follow-up is best done by topographic imaging techniques.

This study included 12 patients. All patients were evaluated by abdominal CT study. Most findings of CT studies were mesenteric calcified or noncalcified lymphadenopathies, ascites, thickened intestinal wall located on the right lower quadrant of abdomen, thickening of peritoneum, mottled soft-tissue densities in omentum and mesenterium. In addition, one of the patients had bilateral calcified adrenal glands and one of them had calcified mass in adrenal gland. If peritoneal thickening, ascites, abdominal lymphadenophaties and thickened intestinal walls are obtained, TBC should be considered in differential diagnosis in developing countries.

Diagnosis was established with color Doppler US and after magnetic resonance imaging. This report describes an unusual appearance of the cisterna chyli that radiologists should be familiar with, especially on the routine conventional gray-scale US to avoid mistaking it for a pathologic condition.

Materials and methods: MR portography findings were retrospectively compared with the results of CDUS examinations in 161 patients, who were suspected of having portal venous system abnormalities. Portal venous vessels were divided into main 5 groups including the main portal vein, its left and right intrahepatic branches, splenic vein and superior mesenteric vein. Imaging findings were classified as normal, occluded, or partially thrombosed. Results of clinical and imaging follow-up examinations including CDUS, MR portography or angiography, if available, were used as a proof of final diagnosis. The potential sites of varicose veins and collateral vessels were also examined by both imaging methods. Results: Vascular abnormalities were identified in 79 of 161 patients. There was a statistically significant agreement between the results of MR portography and CDUS in evaluating portal venous system (j = 0.871, P < 0.05). The sensitivity of MR portography was slightly superior to CDUS in detecting partially thrombosis and occlusion in the main portal venous vessels. In addition, MR portograms were superior to CDUS in the management of patients with portal hypertension by identifying portosystemic collaterals more adequately, and clearly demonstrated portal venous vessels that cannot be visualized at CDUS. Conclusion: Results of present study indicates that contrast-enhanced 3D MR portography is well suited and superior to CDUS in the management of patients with portal hypertension.

Histologically, the most common type of primary bone lymphoma is diffuse large cell type and of intermediate type. We present a case with primary bone lymphoma and treated with 8 cycles of CHOP regimen resulted with partial re- sponse with persisting bone lesions. High dose chemotherapy and autologous peripheral blood stem cell transplantation was performed two years after of diagnosis and, osteolytic lesions on the bones completely disappeared after this treatment. The patient is still in remission without any new bone events and with normal clinical and laboratory findings. Complete disappearance and durable com- plete remission of bone lesions in primary bone lymphoma is very rare, even after high dose chemo- therapy.

This report presents two cases (69-and 10-year-old females) of bleeding gastric varices. The patients were diagnosed as having sinistral portal hypertension. Splenic artery embolization was performed in both patients to overcome intractable bleeding, and the clinical outcome was good.
