Placental Insertion into the Cervix with Cervical Shortening as a Clinical Sign to Suspect Cervico-Isthmic Pregnancy: A Case Report and Literature Review.

The clinical signs of cervico-isthmic pregnancy during pregnancy remain unknown. We herein report a case of cervico-isthmic pregnancy showing placental insertion into the cervix with cervical shortening, with a final diagnosis of placenta increta at the uterine body and cervix. A 33-year-old multiparous woman with a history of cesarean section was referred to our hospital at 7 weeks of gestation with suspected cesarean scar pregnancy.

Recent trends in the prevalence and distribution of colonic diverticula in Japan evaluated using computed tomography colonography.

Background: Computed tomography colonography (CTC) may be superior to colonoscopy and barium enema for detecting diverticula. However, few studies have used CTC to diagnose diverticula.

Aim: To evaluate the current prevalence and distribution of colonic diverticula in Japan using CTC.

Successful control of portal hypertension-related complications after two embolization procedures for multiple and large spontaneous portosystemic shunts in a patient with liver cirrhosis.

Liver cirrhosis is frequently complicated by spontaneous portosystemic shunt (SPSS) due to portal hypertension. Shunt embolization is considered when symptoms related to SPSSs are refractory to endoscopic and/or medical therapies. However, little information is available on the treatment of patients with multiple and large SPSS.

Posterior Reversible Encephalopathy Syndrome with Stroke in Puerperal Woman with High Titer of Anti-Phospholipid IgM Antibody.

Posterior reversible encephalopathy syndrome with stroke is very rare in puerperal women. A 36-year-old nulliparous woman with both rheumatoid arthritis and recurrent pregnancy loss, probably due to a high titer of anti-phospholipid IgM antibody, was referred at 10 weeks of gestation. Low-dose aspirin at 100 mg/day and heparin calcium subcutaneous injection at 10,000 units/day were started before pregnancy and stopped at 35 and 40 weeks, respectively.

Magnetic resonance imaging of degeneration of uterine adenomyosis during pregnancy and post-partum period.

Degeneration of adenomyosis during pregnancy and the post-partum period is very rare. A 42-year-old Japanese parous woman with four normal-term deliveries, who presented with abdominal pain and fever at 22 weeks of gestation with transient increases of the white blood cell count and C-reactive protein, demonstrated sustained inflammation after cesarean section at 29 weeks of gestation due to the occurrence of gestational hypertension with late deceleration. The noncontrast-enhanced magnetic resonance imaging (MRI) at 22 weeks demonstrated a poorly demarcated hypointense area at the posterior uterine wall on T1- and T2-weighted imaging.

Combined assessment using optical colonoscopy and computed tomographic colonography improves the determination of tumor location and invasion depth.

Introduction: An accurate assessment of the depth of tumor invasion in patients with colon cancer is an important part of the preoperative evaluation. Whether computed tomographic colonography (CTC) or optical colonoscopy (OC) is better to accurately determine tumor location and invasion depth has not been definitively determined. The aim of this study was to determine the diagnostic accuracy of tumor localization and tumor invasion depth of colon cancer by preoperative OC alone or combined with CTC.

Spontaneous resolution of post-delivery or post-abortion uterine artery pseudoaneurysm: A report of three cases.

Post-delivery/-abortion uterine artery pseudoaneurysm (UAP) sometimes causes life-threatening bleeding, requiring transarterial embolization (TAE). It is unclear whether some UAP resolve spontaneously. In three patients, UAP resolved spontaneously without TAE.

CT prediction of the degree of ovarian torsion.

Purpose: Torsion angle determines the incidence of necrosis among patients with ovarian torsion. The purpose of this study was to evaluate the association between torsion angle and findings on CT scan.

Materials And Methods: We retrospectively reviewed CT scan findings obtained less than 36 h before surgery for 31 patients with ovarian torsion.

Laterally spreading tumors: limitations of computed tomography colonography.

Aim: To prospectively investigate the detection rate of laterally spreading tumors (LSTs) of the colorectum by computed tomography (CT) colonography (CTC).

Methods: Patients with LSTs measuring ≥ 20 mm detected during colonoscopy were prospectively enrolled in the study. All patients underwent colonoscopy and subsequent CTC on the same day.

Preoperative evaluation of colorectal cancer using CT colonography, MRI, and PET/CT.

Imaging studies are a major component in the evaluation of patients for the screening, staging and surveillance of colorectal cancer. This review presents commonly encountered findings in the diagnosis and staging of patients with colorectal cancer using computed tomography (CT) colonography, magnetic resonance imaging (MRI), and positron emission tomography (PET)/CT colonography. CT colonography provides important information for the preoperative assessment of T staging.

Routine use of dual time ¹⁸F-FDG PET for staging of preoperative lung cancer: does it affect clinical management?

Objective: The objective of this study was to compare the diagnostic accuracy of dual-time-point 18F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) to single-time-point (18)F-FDG PET for staging of preoperative lung cancer.

Methods: Between November 2008 and December 2009, 107 patients who were diagnosed as having lung cancer or strongly suspected of having lung cancer were enrolled. They underwent dual-time-point (18)F-FDG PET following conventional imaging.

A comparative study of degree of colorectal distention with manual air insufflation or automated CO(2) insufflation at CT colonography as a preoperative examination.

Objectives: The purpose of this study was to compare the degree of colorectal distention between manual insufflation using room air and automatic insufflation using carbon dioxide for computed tomography colonography performed as a preoperative examination for patients with colon cancer.

Materials And Methods: Participants comprised 200 patients who underwent computed tomography colonography immediately after colonoscopy from October 2011-2012. The first 100 patients were examined using manual insufflation, and the remaining 100 patients were examined using automated insufflation.

Flank pain, nausea, vomiting and hypotension in a chronic hemodialysis patient with a spontaneous perirenal hemorrhage.

Decreases in blood pressure develop in response to a wide range of clinical disorders. Various factors have been implicated in the development of hemodialysis-associated hypotension, including an impairment of the compensatory processes, an autonomic dysfunction or cardiac failure. The additional presence of concomitant acute abdomen may result in a diagnostically challenging situation.

Intraductal papillary mucinous neoplasm penetrating to the stomach, duodenum, and jejunum demonstrated on MR cholangiopancreatography with an oral negative contrast agent.

A 65-year-old man was referred to our hospital due to epigastric pain. Abdominal enhanced computed tomography (CT) demonstrated marked dilatation of the main pancreatic duct (MPD) and communication to the gastric and duodenal lumen was suspected. Esophagogastroduodenoscopy (EGD) showed a villous tumor with white mucous discharge in the posterior wall of the gastric corpus and duodenal bulb.

Sonographic findings of Sister Mary Joseph's nodule from ovarian cancer.

Sister Mary Joseph's nodule (SMJN), which is known as a malignant tumor metastasized to the umbilicus, is a rare condition. We report ultrasonic findings of SMJN secondary to ovarian cancer in a 66-year-old woman. The umbilical tumor was observed as a hypoechoic mass with punctate hyperechoic foci.
