Objective: To assess the importance of incidental extraspinal findings on Magnetic Resonance Imaging of the lumbar spine in two hospital facilities. Materials and Methods: It was a descriptive and retrospective study from November 2015 to March 2016. The records of patients who had done a Magnetic Resonance Imaging (MRI) scan of the lumbar spine were re-read in search of incidental findings. The incidental findings found were classified using Colonography Reporting and Data System(C-RADS) classification of extracolonic lesions to assess clinical significance. The prevalence of incidental findings was calculated for each facility, as well as the distribution according to age, the organs involved and the clinical importance. A non-detection rate was calculated by confronting the findings of the study with the original reports. Results: The prevalence of incidental findings was respectively 33% (19 out of 36) in Jordan Medical Center (JMC) in Yaounde and 27.74% (106 out of 292) in Jacques Monod Hospital. The extraspinal incidental findings were classified mainly as extracolonic 2 (E2): 58% in each facility. The percentage detection of incidental findings was 5% at JMS and 1.7% at Jacques Monod Hospital. Conclusion: Extraspinal incidental findings are frequent in both hospitals. However, the rate of detection remains very low.
Anterior cruciate ligament (ACL) rupture is one of the most frequently encountered traumatic ligamentous lesions of the knee. Several intrinsic and extrinsic factors are linked to this lesion. Anatomical factors increase the anterior translation of the knee and thus promote the stretching and rupture of the anterior cruciate ligament. Objectives: To determine the anatomical risk factors favouring ACL rupture by comparing morphometric parameters of patients with knee ACL rupture to patients without ACL rupture, as well as the intercondylar notch index and the tibial slopes of the two groups and describing the ruptured ACLs and associated signs. Materials and Methods: We conducted a case-control descriptive analytical study in imaging centres of the General Henri Mondor of Aurillac Hospital Centre in France (CHM) and the Jordan Medical Centre of Yaoundé in Cameroon (CMJ). MRI exam protocols included T1 SE, T2 SE, proton density and Fat Sat sequences, with slices in all three planes. Morphometry knee variables measured in our study were: intercondylar notch index and the tibial slopes. These measurements were obtained from images stored in DICOM format and post processing software OsiriX MD ® for CMJ patients and Explore ® for CHM patients. Results: The study included 92 individuals, 38 in the case group and 54 in the control group. The mean age was 36.6 years for both groups; 35.5 years for the cases and 37.4 years for the controls. The sex ratio was 1.87 men for 1 woman in
Background: Pregnant women are important stakeholders regarding prenatal ultrasound (US) scanning. Their specific needs and preferences have to be ascertained by healthcare providers to ameliorate service delivery. Objective: To assess the pregnant woman's expectations during routine prenatal US scan and her perspective of US safety during pregnancy in a Central African obstetric population. Methods: A cross-sectional descriptive survey of consenting pregnant women who reported for routine prenatal US scan using an anonymous questionnaire. A convenient sample of 200 participants was adopted. Results: Thirty-three (16.8%) respondents (on a total of 196) declared they had never done an US scan. One hundred and eleven (58.4%) on a total of 190 stated that they had not received any information on what ultrasonography is all about. Before the US scan the respondents would like to receive information on the aim or purpose of ultrasonography, possible inconveniences or risks, and on how to prepare before the scan. The most reported expectations were assurance of the wellbeing of the fetus (58%), gender determination (44.5%) and information on fetal position (20.5%). Thirty-four respondents considered ultrasonography as not perfectly safe for the mother or the "baby", with the relevant reasons being the use or production of some potentially harmful "rays". Conclusion: Pregnant women would want to be assured of the wellbeing of the fetus, the gender and position during routine prenatal US. They however need to be informed of its purpose and safety.
Background: Urethral stricture is a disabling condition that remains prevalent due to the upsurge of sexually transmitted infections and traumatic lesions of the urethra during trauma of the pelvis in humans. Objective: Describe the epidemiological, clinical and radiological presentations of male urethral strictures. Method: It was a cross-sectional and descriptive study during a one-year period from January to December 2017 including all male patients presenting for a urethrocystography examination, at the Ngaoundere Radiology and Medical Imaging Center who agreed to participate. The urethrocystography technique depended on patient's condition and was either retrograde, anterograde, or following intravenous urography. The examinations were performed with GE X-ray equipment using Kodak Dry View CRs. The interpretation was performed by a radiologist with at least five years of experience. The variables studied were age, clinic, history, uretrocystography technique and results. The data were collected using a previously established data sheet and processed with Sphinx Plus2 V5 and Microsoft Excel 2010 software. Results: 39 patients were enrolled in this study; the average age of our patients was 43.8 years with extremes of 4 and 76 years. The 50-60 age group (30.7%) was the most affected. Infection (53.9%) and trauma (23.1%) were the most common etiologies; dysuria (38.5%) and diminution of urinary flow (30.8%) were the most patient's complaint. Retrograde urethrocystography (66.7%) was the most performed technic. Minimal bleeding in 46.2% of patients was the most common incident during urethrocystography; 76.9% of patients had a difficult urination and 7.7% an impassable urethral meatus. After interpretation, 84.6% of patients had urethral stenosis, which How to cite this paper: Guena, M.N.,
Objective: Bleeding during the first trimester of pregnancy is common and can be a sign of complication that often necessitates obstetric ultrasound for the assessment of the haemorrhage, and of fetal well being. The aim of this study was to determine the causes of first trimester bleeding on obstetrical ultrasound in our area. Method: It was a cross-sectional descriptive study during a six-month period from May to October 2017. All women who referred to the Regional center of medical imaging of Ngaoundere who agreed to participate in the study with first trimester bleeding were evaluated with clinical history and ultrasonography (US). Ultrasonographic exam was done via transabdominal or endovaginal approaches using GE LOGIQ 7 scanner brand. Microsoft Office Excel 2010 and SPHINX V 4.0 were used for data analysis. Results: A total of 121 of pregnant women who presented vaginal bleeding during the first trimester were enrolled into the study. These Ultrasound examinations represented 37.93% of all obstetric ultrasounds in the first trimester. The patients in this study ranged in age from 16 to 47 years with an average of 30 years. 50 (41.32%) were pregnant for the first time and 24 (19.83%) were primiparous. Mean gestational age was 9 weeks with the extremes of 5 and 12 weeks. 97 (80.2%) reported spontaneous bleeding while in 24 (18.8%) bleeding was mostly caused by sexual intercourse 11 (45.8%). Pelvic pain 91 (75.2%) was the most associated sign. 36 (29.8%) patients were diagnosed as threatened abortions. 27 (22.3%) were diagnosed with incomplete abortions. 4 (3.3%) cases showed an ectopic gestation. 9 (7.4%) cases showed complete abortions. Concordance between clinical diagnosis and ultrasound results was 84%. Conclusions: Bleeding in the first trimester of pregnancy is common in our area. Ultrasonography occupies a prominent place in the etiological diagnosis of bleeding in the first trimester of pregnancy;
