Patients and method: Six-month retrospective study concerning sinus CT scans in the registers of Teaching Hospitals’ Imaging Services of Lomé and Kara (TOGO). It involves patients without distinction of sex, of over 15 years without anomaly that can lead to a modification of the normal anatomical configuration of the paranasal sinuses’ cavities. The analysis has been made by only one radiologist. Results: The frequency of mechanical sinonasal anatomic variants stood at 91.87%. The narrowing of the middle nasal turbinate was the variant mostly observed (55.03%), dominated by the deviation of the nasal septum whose frequency was 25.48%. The narrowing of the infundibulum represented 10.80% of population. They were more represented by the Haller cell which displayed a frequency of 3.60%. The variants venturing to narrow the upper nasal turbinate, represented only by extra turbinates, involved 1.02% of the population. The other variants of mechanical sinonasal anatomic variants represented 25.02%. They were dominated by the maxillary sinus septa (11.2%). Our study showed a feminine predominance which is statistically important for Haller cells (p = 0.037) and the ethmoidbulla hypertrophy (p = 0.0036). Conclusion: The anatomic variants of mechanical sinonasal are very frequent in Togo.展开更多

Methods: A retrospective and descriptive study was carried out at The National and University Teaching Hospital Hubert Koutoukou Maga (CNHU-HKM), of Cotonou in Benin from November 1st to December 31st. A review of CT scans skull was done for the subjects aged at least 16 years old. Anatomic variants of the sphenoid sinuses and adjacent structures have been investigated. Results: 225 CT scans of skull were analyzed. The sellar type was the most common type of pneumatization of sphenoid sinuses (74.7%). Pneumatization of anterior clinoid processes of greater and lesser wings of the sphenoid and of pterygoid processes was observed in 7.1%;4.6%;3.3% and 7.3%;respectively. Protrusion of carotid canals and optic canals, maxillary and vidian nerves were observed in 48.3%;13.1%;18% and 9.5%;respectively. Conclusion: Risky anatomic variants of the sphenoid sinuses and adjacent structures are also described by CT-scan among Beninese. Before any surgery and to avoid bad outcome, a precise approach of these risky anatomic variants must be carried out by using CT-scan.展开更多

The study showed mean of total samples of the width and length of right and left kidneys respectively measurements were 5.354 ± 0.948 and 5.571 ± 0.966 for width and 10.028 ± 1.3684 and 10.060 ± 1.5203 for length, the width and length for right renal artery 5.746 ± 1.2814 and 5.881 ± 1.1444 respectively and for left renal artery 5.894 ± 1.3175 and 4.961 ± 1.3175 respectively. Accessory renal artery is a common but a significant anatomical variant of the renal vascular system, due to its clinical importance. In our sample, the accessory renal artery presence was detected in 6% and displayed a greater variation on the right than the left side. Because this abnormality plays an important role in kidney transplantations, in radiological, vascular and urological interventions, a detailed presentation of accessory renal artery incidence was conducted, gathering from the literature a large number of relevant studies in order to create a classification according to population, gender, side and specimen. And the study concluded that the renal arteries present a broad spectrum of variability in their morphological expression regarding their length, diameter and entrance to the kidney parenchyma. The inferior polar renal artery was found same as the superior polar renal artery, additional arteries’ morphological expression was higher in men than women. This is statistically not significant and variation in the right side was found greater frequency than the left side.展开更多

The types of Accessory renal arteries were 1.8% (7/24) upper pole, 1.8% (7/24) lower pole and 2.5% (10/24) hilus. In males, 4 upper pole, 4 lower pole and 7 hilus. In females, 3 upper pole, 3 lower pole and 3 hilus. The percentage of right accessory renal arteries is almost twice that of the left and more than twice the bilateral accessory arteries.
