Uterine Sarcomas: Are There MRI Signs Predictive of Histopathological Diagnosis? A 50-Patient Case Series with Pathological Correlation.

Purpose: To make clear distinction between two radiological types of uterine sarcomas.

Methods: 50 preoperative MRI were analyzed retrospectively, blinded to histopathology: 11 endometrial stromal sarcomas (ESS), 19 leiomyosarcomas (LMS), 18 carcinosarcomas/malignant mixed Mullerian tumors (MMMT), and 2 smooth muscle tumors of uncertain malignant potential (STUMP).

Results: According to their locations, two radiological types of sarcomas were identified: type 1: intracavitary (ESS, MMMT) and type 2: intramyometrial (LMS, STUMP).

Case series of outcomes of a standardized surgical approach for placenta percreta for prevention of ureteral lesions.

Objective: To report the outcomes of women with placenta percreta who were surgically treated by a specialized technique based on gynecologic oncology experience, and to demonstrate its safety in preventing ureteral lesions and reducing blood loss.

Methods: In the present retrospective study, data from patients with placenta percreta radically treated at Hôtel-Dieu de France, Beirut, Lebanon, between December 2012 and January 2017 were reviewed. Demographic, pathology, and delivery data, medical history, per-operative and postoperative information, and neonatal data were assessed.

Breast Density and Breast Cancer Incidence in the Lebanese Population: Results from a Retrospective Multicenter Study.

Purpose: To study the distribution of breast mammogram density in Lebanese women and correlate it with breast cancer (BC) incidence.

Methods: Data from 1,049 women who had screening or diagnostic mammography were retrospectively reviewed. Age, menopausal status, contraceptives or hormonal replacement therapy (HRT), parity, breastfeeding, history of BC, breast mammogram density, and final BI-RADS assessment were collected.

[Laparoscopic treatment of vaginal agenesis: three cases].

Background: Ninety per cent of cases of congenital vaginal agenesis are represented by the Mayer-Rokitansky-Küster-Hauser syndrome, the remaining 10% being represented by the testicular feminization syndrome and vaginal aplasia. Numerous surgical methods for the treatment of vaginal agenesis have been described. Neovagina construction by sigmoid colpoplasty seems to be the best surgical option as regards the anatomical and functional outcome.

Ultrasound as an adjunct to radiography in minor musculoskeletal pediatric trauma.

Purpose: To assess the value of ultrasound as an adjunct to radiography in minor musculoskeletal pediatric trauma.

Methods: Fifty children with 53 suspected fractures were referred for upper and/or lower limbs X-rays, followed by ultrasound. On radiography, we noted presence of fracture, of soft tissue thickening, or absence of any lesion.

Characterization of papillary projections in benign versus borderline and malignant ovarian masses on conventional and color Doppler ultrasound.

Objective: The purpose of our study was to evaluate on endovaginal ultrasound the morphologic and color Doppler characteristics of papillary projections in benign compared with borderline and malignant epithelial stromal ovarian tumors.

Materials And Methods: A total of 283 women (mean age, 52 years; age range, 20-85 years) with 343 operated adnexal masses comprising 167 epithelial stromal tumors of the ovary with 76 tumors containing papillary projections at pathology were retrospectively studied on ultrasound. We systematically evaluated the topography of the papillary projections, the morphologic features of the largest papillary projection, and the presence or absence of color Doppler findings.

[Anatomy of the larynx with 64-channel multidetector CT].

Knowledge of axial anatomy of the different laryngeal structures, identification of the plan of the cords, and relations between the true and false vocal cords is essential for laryngeal surgery where anatomical and radiological correlation is necessary for optimal orientation and guidance. This review constitutes an atlas of axial anatomy of the larynx obtained from a multidetector CT scan, describing the skeletal cartilage, the different folds constituted by laryngeal ligaments covered by mucosa, and the fatty laryngeal spaces. It shows that CT scan and the different reconstructions specifically virtual endoscopy are a valuable adjunct in laryngeal exploration.

BI-RADS: what do we need to know? Advantages and limitations.

BI-RADS (Breast Imaging and Reporting Data System) is meant to transform breast imaging language to a universal one by defining the related descriptive terms, the statistical definitions, and providing recommendations for radiological reports and data archiving system. The latest version covers three imaging modalities, i.e.

History of mastectomy before and after Halsted.

The operation described by Halsted, in 1894 and called radical mastectomy, represents a milestone in the treatment of breast cancer. It consisted of removal of the breast, muscles and axillary lymph nodes. The pre-Halsted era saw attitudes ranging from the willful abstention to brutal treatments by cauterization or amputation.

[Hydatid disease diagnosed following a pulmonary embolism].

Hydatidosis is a parasitic disease found worldwide, particularly in Mediterranean countries, caused by Echinococcus granulosis infection. Humans are an intermediate and accidental host in the cycle of this parasite. The hydatid pulmonary arterial embolism is extremely rare, usually arising in the heart or the liver.

[The echocardiographic interpretation of musculoskeletal disease pathology in children].

Osteoarticular ultrasound, a well established technique in adults, appears to be very useful also in children because of the non ossification of cartilaginous structures, the possibility to avoid sedation and irradiation, and hence the use of scanner and MRI will be reduced. This is a review of the clinical applications of musculoskeletal ultrasound in the pediatric population. Pictorial examples of cases collected between January 2003 and December 2006 of different pathologies encountered in Lebanon are displayed with a discussion of congenital malformations, traumatic lesions, inflammatory and infectious lesions, bone dystrophy and dysplasia, metabolic and tumoral lesions.

Ovarian hyperthecosis on grayscale and color Doppler ultrasound.

Objectives: To describe the grayscale and color Doppler ultrasound findings in women with ovarian hyperthecosis.

Methods: In a retrospective study, we reviewed the findings on ultrasound examination of the ovaries in 10 patients with proven hyperthecosis. Clinical features had been recorded and testosterone levels measured in all cases.

[Value of US imaging following mastectomy].

Purpose: To assess the value of US of the mastectomy site at the time of follow-up of the contralateral residual breast.

Materials And Methods: Over a 5 year period, 251 patients with previous mastectomy underwent 505 unilateral mammographies with US of the mastectomy site. The time delay between imaging and mastectomy ranged between 1-15 years, with a mean of 7.

[Limb fractures: ultrasound imaging features].

US, a non-irradiating imaging modality, is complementary to radiographs in the evaluation of limb fractures. US may in some cases demonstrate or suggest the presence of a fracture without corresponding abnormality on radiographs, or confirm or exclude a possible fracture detected on radiographs. Knowledge of the US features of fractures is necessary.

[Non invasive imaging of bilateral vertebral arteries agenesis].

Imaging descriptions are lacking for vertebral artery variants reported in the anatomy literature. We report thus a variant of vertebral arteries discovered incidentally in a patient admitted for aortocoronary bypass. Doppler of the supra-aortic arches revealed the absence of cervical segments of both vertebral arteries.

The multiple ultrasound patterns of ectopic pregnancy.

Ectopic pregnancy (EP) has a variable and misleading clinical presentation contributing to the confusion with medical or other gynecological disorders. The rapid recourse to diagnostic methods, human chorionic gonadotropin (beta-hCG) titers and transvaginal ultrasonography, represents the best approach not only in the early diagnosis but also in the management and monitoring of patients with diagnosed EP. The purpose of this article is to provide a pictorial essay about EP and its multiple ultrasound (US) patterns.

[Pseudoaneurysm of the abdominal aorta due to retroperitoneal lymph nodes, diagnosed by Doppler ultrasound and treated by embolization].

Objective: To report a case of pseudoaneurysm of the abdominal aorta due to retroperitoneal enlarged lymph nodes.

Materials And Methods: A 40 years old patient, with known sarcoma and metastatic retroperitoneal lymph nodes was referred for abdominal ultrasound because severe abdominal pain after defecation.

Results: The Doppler examination revealed magma of retroperitoneal lymph nodes surrounding the abdominal aorta inside of which a saccular collection of circulating blood, communicating with the aorta, was detected.

Retroperitoneal lymphangioleiomyoma mimicking ovarian tumor emerging after tamoxifen therapy.

Background: Lymphangioleiomyomas are lymphatic masses that can be associated with lymphangioleiomyomatosis. They are usually associated with pulmonary involvement.

Case: A 44-year-old premenopausal woman with breast cancer treated with adjuvant tamoxifen presented with abdominal distension.

Spontaneous detorsion of the ovary: can it be diagnosed by MRI?

Purpose: To determine whether recent progress in imaging has made it possible to diagnose spontaneous detorsion, which is an accepted concept in the gynecological literature but until now has been a presumptive diagnosis that could not be confirmed because of the lack of imaging proof.

Materials And Methods: We searched for patients who had a diagnosis of spontaneous detorsion on MRI between January 2000 and January 2003, and selected only patients who met a selection of strict criteria, including mainly enlargement and hyperintensity of ovarian stroma on T2-weighted (T2W) images, clinical findings compatible with torsion and detorsion, and return of the stroma to normal size on follow-up examinations. Other signs of torsion, such as tubal thickening, were appreciated but not mandatory.

Variable MR findings in ovarian functional hemorrhagic cysts.

Purpose: To describe the magnetic resonance (MR) findings in ovarian functional hemorrhagic cysts (FHC).

Materials And Methods: A total of 21 patients with 22 FHC, proven by follow-up ultrasound (US) in 11 women and surgery in 10 women, had US and MR examinations within 24 hours. The study was limited to cysts with obvious an echogenic pattern.

[Regression of Morton neuroma after local injection of steroids].

Morton neuroma is a non neoplastic lesion corresponding to perineural fibrosis encircling the common interdigital plantar nerve. Several therapeutic approaches are possible: conservative treatment or surgery. We report a case treated by local steroid injection where follow-up MR showed near complete regression of the lesion.
