BACKGROUND: Pancreatic cystic neoplasms (PCNs) are a spectrum of neoplasms that can be benign or malignant. The accuracy of diagnosis is critical for this disease since different types of PCNs are treated differently using various modalities. The use of a multidisciplinary team (MDT) has been shown to improve the management and outcomes of various diseases. We aimed to determine the performance of MDT in the management of PCNs. METHODS: We retrospectively reviewed 167 pathologically-proven PCN patients and divided them among three groups according to their surgical data and treatment modalities: 1) historical control group (HC group); 2) concurrent control group (CC group); and 3) MDT group...

Background: Angiomyofibroblastoma (AMFB) is a benign mesenchymal tumor most commonly found in the female genital tract of premenopausal women. Although rare, AMFB is an important consideration in the differential diagnosis of vulvar and vaginal masses, as it must be distinguished from aggressive angiomyxoma (AA), a locally recurrent, invasive, and damaging tumor with similar clinical and pathologic findings. Case: We describe a patient with a 4 cm vaginal AMFB and the relevant preoperative radiographic imaging findings...

Purpose: The purpose of this study was to investigate the final outcomes of magnetic resonance imaging (MRI)-identified additional lesions (MRALs) in breast cancer patients and the role of second-look ultrasound (SLUS) and imaging-guided interventions. Methods: We analyzed breast cancer patients with MRALs on preoperative MRI between January and June 2012. MRALs were defined as additional lesions suspected on MRI but not suspected on mammograms or ultrasound. The malignancy rate of MRALs, MRI-based Breast Imaging Reporting and Database System (BI-RADS) category, positional relationship with the index cancer, MRI-concordant lesion visibility on SLUS, performance of imaging-guided interventions, and total mastectomy (TM) rates were evaluated for the confirmed lesions...

INTRODUCTION:  Rhabdomyomatous dysplasia (RD) is a pathologic finding in CPAMs that was incorrectly attributed to their malignant potential. The increasing recognition of extrathoracic (intradiaphragmatic and intraabdominal) congenital pulmonary airway malformations (CPAMs) offers a clue to the origin of RD. We hypothesize that the presence of RD is related to the CPAM's anatomic location. MATERIALS AND METHODS:  Retrospective review was performed of all children who underwent resection of a CPAM during a 10-year period...

BACKGROUND: Data from the American College of Surgeons National Surgical Quality Improvement Program identified our hospital as an outlier for preoperative computed tomography (CT) use in the diagnosis of acute appendicitis in children. We performed a quality improvement project to reduce this utilization in favor of ultrasound-based diagnoses (ultrasonography [US]) through creation and implementation of an evidence-based appendicitis algorithm. METHODS: Over a 2-y period (1 y preceding and 1 y following institution of the algorithm), the clinical information of all pediatric patients operated on for suspicion of acute appendicitis following imaging studies in our institution was collated...

Normal-sized ovarian carcinoma syndrome (NOCS) is a rare condition characterised by malignancy identified in ovaries of normal size with abdominal metastasis. We report two cases of advanced ovarian carcinoma with ovaries of normal size. The first case was a 13-year-old adolescent with malignant ascites and bilateral normal sized multicystic ovaries detected on ultrasound. Serum cancer antigen 125 (CA 125) and lactate dehydrogenase were markedly raised. A computed tomography (CT) scan showed the presence of thick omental cake but no ovarian tumour...

BACKGROUND: Tertiary hyperparathyroidism is a significant issue in renal failure patients and some require surgery to control their serum calcium. A number of imaging techniques are used to localise the position of the parathyroid glands prior to surgery. Currently, a combination of ultrasound and isotope preoperative localisation imaging is accepted as useful in parathyroid surgery for primary disease. However, the use of pre-operative imaging in parathyroid surgery in renal failure patients is uncertain...

RATIONALE: Inflammatory myofibroblastic tumors (IMTs), particularly breast IMTs, are rare neoplastic lesions typically associated with a favorable prognosis. Breast IMTs are easily misdiagnosed as other types of malignant lesions, and therefore there is a significant unmet need for a better preoperational differential diagnosis based on imaging manifestations. Here, we report the imaging findings of a breast IMT and compare our findings with previously published features of breast IMTs...

Coronary surgery performed on an arrested heart, using one internal mammary artery and a saphenous vein carries two main potential drawbacks: the known failure rate of vein grafts and the relatively high rate of neurologic injury. To address these concerns, we describe a technique that achieves complete revascularization without manipulating the ascending aorta (anaortic, off-pump) and utilizing total arterial grafts. All patients undergo thorough preoperative investigation, including bilateral carotid, vertebral and subclavian artery Duplex ultrasounds...

Preoperative pathologic diagnosis of pelvic tumors is mandatory for proper management of patients like neoadjuvant chemotherapy and interval debulking. Currently there are many minimally invasive methods available which include fine-needle aspiration cytology (FNAC) and trucut biopsy, mostly complimentary to each other. FNAC is a cheap, rapid and sensitive method for diagnosis of pelvic tumors. It can be done as an outpatient procedure without complications. But with it, the tissue architecture cannot be seen...

BACKGROUND: Innovations in medicine are often due to the simplicity of a certain activity, interaction, even counteraction, or a mistake leading to a subsequent final optimal outcome. Innovations could also be due to conclusions based on targeted clinical or sporadic, as well as completely random observations. The genius of an approach or statement is often based on the "iron logic", which in turn is based on irrefutable data or facts. These are often observations or results from actions that happen right before our eyes and provide advantages or prerequisites for the better future development of things (in this case, disease) concerning certain groups of people (in these case-patients)...
