Objective: To perform a comparative analysis of the linear dimensions of the facial skull that are the most signifi cant in determining asymmetry in persons of diff erent sex on spiral computed tomograms (SCT).Materials and Methods: The CT scan of 104 people of both sexes (women – 52%, n = 54, men – 48%, n = 50) were studied. Measurements were made using a standard digital ruler of a computer tomograph workstation, and the asymmetry of the skulls was assessed using the “fan” method. The results were processed using the Excel program.Results: In the male and female series of SCT, according to the size of the intervals of sigma of linear dimensions of the facial skull, the occurrence rate of asymmetry of varying severity was determined.Conclusion: In the male series of SCT, right-sided asymmetry of the linear dimensions of the facial skull prevails in all “fans”, in the female – right-sided asymmetry in the upper and lateral “fans”, but left -sided asymmetry in the lower “fan”. Statistically signifi cant linear dimensions of the facial skull were revealed to determine the severity of asymmetry in both sexes. In the upper “fan”, these are the distances from the nasion to the zygomaxilar (N-Zm), from the nasion to the frontonazale (N-Fn), prevailing on the right in both sexes. In the lower “fan”– the distance from the supraspinal to the zygomaxilar (Ss-Zm), and in the lateral “fan” – the distance from the zygomaxilar to the frontonasal (Zm-Fn), prevailing on the right in both sexes. An insignifi cant or physiological and moderate degree of asymmetry in the size of the facial skull depending on gender was revealed, which did not require correction.

Abstract Introduction Traumatic head injury with extradural hematoma (EDH) is seen in 2% of patients. Development of EDH on the contralateral side is an uncommon complication that has been reported in various case reports. Case Report We report here a case of an 18-year-old male who had a road traffic injury. He was diagnosed as a case of left-sided large frontotemporoparietal acute extradural bleed with a mass effect toward the right side. He was managed with urgent craniotomy and evacuation of hematoma. A noncontrast computed tomography (NCCT) scan performed 8 hours after postoperative period showed a large frontotemporoparietal bleed on the right side with a mass effect toward the left side. He was again taken to the operating room and right-sided craniotomy and evacuation of hematoma were performed. A postoperative NCCT scan revealed a resolved hematoma. The patient made a complete recovery in the postoperative period and is doing well. Conclusion Delayed onset epidural hematoma is diagnosed when the initial computed tomography (CT) scan is negative or is performed early and when late CT scan performed to assess clinical or ICP deterioration shows an EDH. The diagnosis of such a condition requires a high index of suspicion based on the mechanism of injury along with fracture patterns. Additionally, change in pupillary size, raised intracranial pressure, and bulging of the brain intraoperatively are additional clues for contralateral bleeding. Neurologic deterioration may or may not be associated with delayed EDH presentation. An early postoperative NCCT scan within 24 hours is recommended to detect this complication with or without any neurologic deterioration.

Purpose To compare surgeons' operative assessments of residual disease (RD) to those identified on postoperative computed tomography (CT) scans in patients with advanced ovarian carcinoma reported to have undergone optimal primary cytoreduction. Patients and Methods All patients at one of two institutions, who were scheduled to have primary surgery for presumed advanced ovarian cancer, were asked to consent to a postoperative CT scan if cytoreduction to ≤ 1 cm RD was reported. CT scan findings were graded using a qualitative analysis scale from 1 (normal) to 5 (definitely malignant). Results From January 2001 to September 2006, 285 patients were enrolled. A total of 78 patients met eligibility criteria and had postoperative CT scans. In 41 cases (52%), postoperative scan findings correlated with the surgical report of no RD more than 1 cm, and in seven cases (9%), the CT findings were indeterminate. In 10 cases (13%), more than 1 cm RD was noted by the radiologist as probably malignant, and in 20 cases (26%), definitely malignant. In these 30 cases, the radiologically reported median largest residual mass was 1.9 cm (range, 1.1 to 5.1), with RD more than 1 cm reported most commonly in the right upper quadrant (15 patients [50%]) and central abdomen (nine patients [30%]). Conclusion There was only a 52% correlation between surgeons' assessments and postoperative CT scan evaluations of RD in patients reported to have undergone optimal cytoreduction. Further study is required to determine whether this lack of correlation is due to rapid interval tumor regrowth, RD underestimated by the surgeons, and/or overestimated by the radiologists; and to determine the clinical implications of these discrepancies.

Abstract Background and Aim The purpose of present study was to obtain comprehensive data of morphometric and anatomical details of jugular foramen. Materials and Methods The study was performed on 30 dry adult human skulls along with computed tomography (CT) scans from 30 adult patients. The parameters observed were dimensions, shape, margins, confluence, septations, and distance from jugular foramen to mastoid base. Result In the dry skull observations, only anteroposterior diameter (APD) was significantly different between the right and left side, while for the CT scan observations both transverse diameter and APD exhibit significant difference. Conclusion We believe that data from the present study will help radiologists and neurosurgeons for diagnosis and treatment of skull base pathology around jugular foramen.

The aim of this study was to determine the path of screw placement to avoid breaching the articular surface of both lunate and scaphoid bones at the radiocarpal and midcarpal joints. An Acutrak screw was inserted into the right scapholunate joint of ten cadavers starting immediately distal to the tip of the radial styloid and aiming for the tip of the ulnar styloid. The articular surfaces of the scaphoid and lunate bones in all ten cadavers were exposed and examined. A computed tomography (CT) scan of four wrists was performed. Eight of the ten cadavers had no perforation or destruction of the articular surfaces. Screw stabilization of the scapholunate joint can be performed without perforation or destruction of the lunate or scaphoid surfaces. We recommend that if this form of fixation is being used then the screw should be inserted commencing at the radial styloid tip and aiming for ulnar styloid tip, under radiological guidance.

Ankle fractures are more often intrasynovial and lead to impression changes. The research includes the studying of mechanical properties of distal epimetaphis and spongy bones density according to spiral computed tomography data. The research brought out that external and back surfaces of tibia are less dense. It explains the reasons of impression deformation of lateral surface of tibias distal plateau in cases of Dupuitren-typed fracture. This information is necessary to make the right choice of treatments tactic

ABSTRACT Introduction Concha bullosa is the most common anatomic variation of osteomeatal complex region that is generally seen in the middle turbinate (MT). Materials and methods A 25-year-old male presented with headache and nasal obstruction. Computed tomography (CT) scan documented right paradoxical MT. The right MT also showed aerated concha bullosa with narrow right osteomeatal area. Routine preoperative laboratory tests were within normal limits. Results This case of concha bullosa in paradoxically bent MT was reported, described, and could be safely managed endoscopically. Patient was symptom free up to date without any complication, recurrence, or other pathology. Conclusion Computed tomography may easily identify such uncommon anatomic variations of the osteomeatal region. This directs the surgeon attention to these variations as a cause of headache and osteomeatal area obstruction. How to cite this article El-Anwar MW, Ali AI.

Anomalous Pulmonary Venous Connection

Total anomalous pulmonary venous connection is a rare congenital cardiac anomaly in which the pulmonary veins have no connection with the left atrium and connect directly to the right atrium or to one of the systemic veins. In the diagnosis of total anomalous pulmonary venous connection, the presence and severity of the venous obstruction is important. Computed Tomography (CT) imaging is known to be a useful method for the evaluation of total anomalous pulmonary venous connection. Here we report 3 cases of total anomalous pulmonary venous circulation (TAPVC) where 32 slice CT scan played an important role in pre-operative diagnosis and management. Age of the patients ranged from seven months to sixteen years. Symptoms of the patients’ varied from fatigue, shortness of breath, mild cyanosis and reduced growth for their age. Echocardiography done revealed dilated right cardiac chambers and atrial septal defect (ASD) with suspicion of TAPVC. CT scan was performed and it provided detailed information about intra-cardiac anatomy, pulmonary veins and their confluence, route, drainage and most importantly their distance and relation with the left atrium. It also provided information about coronary sinus and its drainage. This information is very important for surgical mapping and planning. Ibrahim Card Med J 2016; 6 (1&2): 73-77
