Pseudomyxoma peritonei: some different sonographic findings.
Summary of "Pseudomyxoma peritonei: some different sonographic findings."
The purpose of our study was to assess the sonographic features of pseudomyxoma peritonei (PMP). MATERIALS AND
All records of peritoneal biopsies under the guidance of ultrasound in our institutional database from April 2007 to June 2011 were retrospectively reviewed. 19 cases of PMP and 279 cases of other peritoneal lesions were included in the study. The sonograms of peritoneum, ascites, and parenchymal organs involved by PMP were evaluated, respectively, and compared with sonograms of other peritoneal lesions.
Anechoic areas were found in 89.5% cases of PMP at high frequency of insonation and the sensitivity in indicating PMP was 100%. In the pelvic cavity, echogenic foci in ascites of PMP in 52.6% cases were mobile. The specificity of "starburst" appearance and sensitivity of scalloping of the liver margin were relatively high (82.3 and 88.1%), but the sensitivity and specificity (57.9 and 42.1%) of these two signs were relatively low.
Anechoic area in the thickened peritoneum was a specific sign in indicating the diagnosis of PMP and high-frequency transducer could reveal these tiny anechoic areas more explicitly. In the pelvic cavity, echogenic foci in ascites of PMP could be observed to be mobile and scalloping of the liver margin and "starburst" appearance also played a significant role in indicating PMP.

Medical and Biotech [MESH] Definitions
A condition characterized by poorly-circumscribed gelatinous masses filled with malignant mucin-secreting cells. Forty-five percent of pseudomyxomas arise from the ovary, usually in a mucinous cystadenocarcinoma (CYSTADENOCARCINOMA, MUCINOUS), which has prognostic significance. Pseudomyxoma peritonei must be differentiated from mucinous spillage into the peritoneum by a benign mucocele of the appendix. (Segen, Dictionary of Modern Medicine, 1992)
Work that consists of a conference of physicians on their observations of a patient at the bedside, regarding the physical state, laboratory and other diagnostic findings, clinical manifestations, results of current therapy, etc. A clinical conference usually ends with a confirmation or correction of clinical findings by a pathological diagnosis performed by a pathologist. "Clinical conference" is often referred to as a "clinico-pathological conference."
Intentional falsification of scientific data by presentation of fraudulent or incomplete or uncorroborated findings as scientific fact.
Porphyrins with four methyl and four propionic acid side chains attached to the pyrrole rings. Elevated levels of Coproporphyrin III in the urine and feces are major findings in patients with HEREDITARY COPROPORPHYRIA.
Medical Records, Problem-oriented
A system of record keeping in which a list of the patient's problems is made and all history, physical findings, laboratory data, etc. pertinent to each problem are placed under that heading.
Urachal mucinous cystadenocarcinoma causing pseudomyxoma peritonei is very rare. We report a case of a 59-year-old man with urachal mucinous adenocarcinoma associated with pseudomyxoma peritonei, and...
Pseudomyxoma peritonei (PMP) is a borderline malignancy, simulating carcinomatosis and generally arising from perforation of an appendiceal mucinous tumour. Some patients have coincidental dual pathol...
Determining the Association Between Preoperative Computed Tomography Findings and Postoperative Outcomes After Cytoreductive Surgery and Perioperative Intraperitoneal Chemotherapy for Pseudomyxoma Peritonei.
BACKGROUND: This study evaluates the accuracy of computed tomography (CT) scoring of the peritoneal cancer index (PCI) and examines its association with surgical morbidity and outcomes in pseudomyxoma...
A Phase II Study of Surgical Debulking With Peritonectomy and Biweekly Intraperitoneal 5FU With Systemic Oxaliplatin/5FU/Leucovorin in Patients With Pseudomyxoma Peritonei or Peritoneal Carcinomatosis
This study prospectively evaluates a multidisciplinary approach to patients with intraperitoneal carcinomatosis at Washington University. Patients with peritoneal carcinomatosis or pseudo...

to evaluate if sonographic measure of short uterin cervix, sludge in amniotic fluid and abnormal doppler of the uterin artery can predict preterm labor
The investigaotors want to establish a real-time and computerized score reporting system based on the significant predictors of the measured sonographic parameters and demographic data.
The purpose of this study is to study normal sonographic(ultrasound)anatomy of the soft tissues of the foot in normal volunteers.
