False positive 18FDG PET-CT results due to exogenous lipoid pneumonia secondary to oily drug inhalation: A case report.

Rationale: Exogenous lipoid pneumonia is a rare condition due to abnormal presence of oily substances in the lungs. It is a rarely known cause for false positive FDG PET-CT results and can sometimes lead to invasive investigations. Searching and finding the source of the oily substance is one of the keys to the diagnosis.

The value of pelvic MRI in the diagnosis of posterior cul-de-sac obliteration in cases of deep pelvic endometriosis.

Objective: The objective of our study was to define relevant MRI signs allowing preoperative diagnosis of posterior cul-de-sac obliteration in patients with deep pelvic endometriosis.

Materials And Methods: This retrospective study included patients who underwent pelvic MRI completed by a laparoscopic examination. Three radiologists performed the MRI review blinded and recorded the following signs: sign 1, retroflexed uterus; sign 2, retrouterine mass; sign 3, displacement of intraperitoneal fluid; sign 4, elevation of the fornix; and sign 5, adherence of bowel loops.

Placement of metallic biliary endoprostheses in complex hilar tumours.

Purpose: To assess the technical success, clinical success and complications after 1 month of percutaneous biliary drainage with the placement of several metallic endoprostheses in complex hilar liver tumours.

Materials And Methods: This is a retrospective study, on a homogenous target population of 68 consecutive patients, who underwent multiple percutaneous biliary drainage for complex hilar tumour (Bismuth type II, III and IV) between August 1998 and August 2010. Patients benefiting from previous endoscopic drainage were excluded from the study.

Inhalation study of polymethyl methacrylate following radiologist exposure during percutaneous vertebroplasty.

Objective: To assess the atmospheric concentrations of methyl methacrylate (MMA) vapors during percutaneous vertebroplasty for the interventional radiologist and the other operating room staff.

Materials And Methods: During percutaneous vertebroplasty, a polymethyl methacrylate (PMMA) mixture (about 20 mL) was prepared with a mixing system in a normally ventilated room. Atmospheric concentrations of MMA vapors were measured by a gas absorbent badge for individual exposure (GABIE) passive sampler attached to the surgical gowns of the interventional radiologist and the other operating room staff over a period of 460 min.

[Discoscanner: indications, technique, tips and tricks, interpretation].

Discography test associated with the scanner (discoscanner) is an exam that has been a renewed interest in recent few years. Thanks to the emergence of new interventions such as disc prosthesis, the procedures require confirmation of the disc level to deal with and the origin of discogenic symptoms. The aim of this paper is to describe the techniques, challenges and tips as well as the interpretation of functional and morphological examination.

MRI characteristics of the uterine junctional zone: from normal to the diagnosis of adenomyosis.

Objective: MRI was the first imaging technique to permit the visualization of the uterine junctional zone and remains the imaging method of choice to evaluate it and its associated pathology.

Conclusion: Adenomyosis can be diagnosed using MRI with a diagnostic accuracy of 85%. The most important MR finding in making the diagnosis is thickness of the junctional zone exceeding 12 mm.

[Splenic artery aneurysm: diagnosis and endovascular therapy].

Splenic artery aneurysms are now diagnosed more frequently thanks to the increase and improvement in different imaging techniques. In case of rupture they are potentially life threatening and thus in certain cases may require appropriate preventive treatment. This treatment should be offered to patients with suspected pseudoaneurysms, with an aneurysm larger than 20mm in diameter, or which is progressing.

EGFR Targeting in Hormone-Refractory Prostate Cancer: Current Appraisal and Prospects for Treatment.

The incidence of prostate cancer increases with age and because of its high prevalence this disease has become a major public health concern. Despite advances in our understanding of the biological mechanisms responsible for the development of this cancer, the transition to the hormone refractory stage (HRPC) and metastatic progression pose real problems of clinical management. Currently, docetaxel chemotherapy has been shown to have a slight but significant impact on survival, though the gain in median survival is still less than three months.

Anterior pelvic endometriosis: MRI features.

Many atypical locations for deep endometriosis exist that are not well known to both the radiologist and gynecologist. This work explores these unusual localizations, which we have arbitrarily grouped under the term "anterior endometriosis" in contrast to the more common posterior presentation of deep endometriosis that has been so well described in the literature. Parietal and inguinal involvement is first detailed, followed by a description of deep endometriosis involving the urinary system and anterior supporting ligaments of the uterus.

MR features of the levator ani muscle in the immediate postpartum following cesarean delivery.

Introduction And Hypothesis: We wanted to show that at the time of cesarean delivery, the active process of labor itself was sufficient to create early alterations of the pelvic floor musculature as detectable via magnetic resonance imaging (MRI).

Methods: Thirty primipara patients underwent pelvic MRI between the second and third day after cesarean delivery. Ten patients had a cesarean without labor while 20 patients underwent urgent cesarean delivery after the onset of labor.

[Evaluation of two classifications systems for pelvic prolapse on dynamic MRI].

Purpose: To determine the usefulness of two classification systems for pelvic prolapse on MRI.

Materials And Methods: Prospective study of 30 patients with symptoms of pelvic prolapse performed in a single center. All patients underwent clinical evaluation followed by dynamic pelvic MRI within 15 days.

Utility of vaginal and rectal contrast medium in MRI for the detection of deep pelvic endometriosis.

Objective: To study the sensitivity of MRI performed utilising vaginal and rectal opacification with ultrasound gel in the detection of deep pelvic endometriosis.

Material And Methods: This was a prospective monocentric study. All patients evaluated by the gynaecologist for pelvic pain, endometriosis or infertility were included.

[Anatomy of the female pelvis on MRI: value of intravaginal contrast].

Purpose: Prospective monocentric study to determine the feasibility, tolerability and diagnostic value of intravaginal contrast to assess female pelvic anatomy on MRI.

Materials And Methods: Forty-nine consecutive women referred for MRI evaluation of the pelvis, irrespective of the indication, were included in this study. The MR imaging protocol consisted of axial and sagittal T2W images before and after intravaginal instillation of sterile US gel.

[MR imaging evaluation of endometrial carcinoma].

Prognosis for endometrial carcinoma is closely related to cell type and tumor grade but also to local staging using the FIGO classification. MRI, under specific technical conditions, allows excellent depiction of the degree of myometrial tumor extension. It also has an excellent specificity for the detection of cervical extension.

Ovarian metastasis from choroidal melanoma.

Ocular melanoma has a strong tendency to metastasize often several years after its initial diagnosis was made. We report on the case of a 50-year-old woman who was treated 20 years earlier for an ocular melanoma and currently seen regularly in our institute for liver metastases that were treated by chemotherapy. After three treatments, a check-up with computed tomography demonstrated the presence of a right ovarian mass.

MR cholangiopancreatography features of the biliary tree after liver transplantation.

Objective: Our objective was to show the usefulness of MR cholangiopancreatography in assessing biliary complications after liver transplantation.

Conclusion: MR cholangiopancreatography is the best noninvasive tool for the diagnosis and assessment of biliary complications.

Incarceration of the appendix complicating a uterine perforation following surgical abortion: CT aspects.

A 39-year-old patient was evaluated for pelvic pain and infection following a surgical abortion performed via aspiration curettage. A pelvic computed tomography (CT) revealed an invagination of fat in the uterine wall accompanied by an abscess in the rectouterine pouch. Laparoscopic exploration revealed an incarcerated cecal appendix within the myometrium with necrosis of the appendiceal base as the culprit.

Lipomas of the right colon: report on six cases.

We report six cases of lipomas of the right colon, of which one was affected by two lesions. Two cases presented with episodes of partial occlusion; the others did not present with particular symptoms. The diagnoses were based on imaging by computed tomography, which demonstrated an intraluminal formation of fatty density, not associated with tissual components or hypervascularization.

Torsion of a uterine leiomyoma: MRI features.

We report a case of a patient admitted to our hospital for acute pelvic pain. Ultrasounds and abdominal CT scan found a voluminous mass situated in the upper urinary bladder and contiguous to the uterus and to the ovaries. Magnetic resonance imaging identified a pedicle connecting the uterus to the mass which had an aspect of a necrobiotic leiomyoma.

Prophylactic use of noninvasive ventilation in patients undergoing lung resectional surgery.

Question Of The Study: We studied whether prophylactic use of noninvasive pressure support ventilation (NIPSV) administered pre- and postoperatively may reduce the postoperative pulmonary function impairment.

Patients And Methods: Prospective randomized clinical trial. Thirty-nine patients with a preoperative FEV(1) <70% of the predicted value scheduled for elective lobectomy related to lung cancer were enrolled.
