Background/Aim: The present study was directed to investigate the accuracy of ultrasound (USG) in early detection of developmental dysplasia of the hip (DDH) to prevent permanent complications. Material & Methods: A total of 276 infants was investigated; their ages range from 1 -6 months. Patients referred from the clinic based on clinical assessment (mainly Barlo & Ortolani maneuvers). Then the patient's hips were examined by expert radiologists in USG scan. After that, dynamic (coronal and transverse) & static ultrasound views evaluated by the same radiologist using Graf's criteria. Infants with abnormal ultrasound findings suggestive of DDH were followed up after 4 -6 weeks by the same investigator to monitor the progress. At the same time, the patient referred to a specialist for conservative management from the first positive findings. Results: Among the 276 referred patients, infants with normal stable hips (Graf Type I and Type II a+) were 221 (80%), 155 of them were female and 66 male infants. Infants with unstable hips based on Graf's criteria (Type II a-, II b, II c and Type III a) were 55 (20%). Out of 55 with abnormal findings, the affected hips on both sides, right and left were: 5 cases (1.8%), 7 (2.5%) and 43 hips (15.5%) consecutively. Out of 55 infants affected; 3 referred to tertiary centers for further surgical management while 52 managed conservatively. Conclusion: Delayed treatment rates of DDH and complications could be reduced by the usage of the USG after the first month of life. In addition to physical assessment, USG for high-risk infants will provide more accurate diagnosis and minimize complications.

Purpose: Cervical spine is considered to be the most moving part of vertebral column. It is located in a very important part of the body i.e. neck having some very important structures related to it. Any age related changes occurring in such a part of vertebral column may lead to many disorders and disabilities. Complete familiarity of this entire region anatomically as well as radiologically is therefore of utmost importance for the diagnosis and management of such disorders. Aim of this work is to evaluate the frequency of age related degeneration in cervical spine in Saudi adult asymptomatic subjects using CT scan images. Methods: In this study, 105 cases of symptomless adults ranging between 18-90 years of age were included. The cases were classified into 3 groups; adult group (18-35 years old), middle age group (36-55 years old) and old age group (56-90 years old). Their CT scans were performed in the department of radiology, King Khalid Hospital, Al Kharj and studied for any age related changes. Results: The first age group category included 35 cases; 20 had normal and 15 degenerative changes. The second category included 35 cases; 3 had normal and 32 degenerative changes. The third category included 35 cases. Single had normal and 34 degenerative changes. Conclusion: Asymptomatic degenerative changes are common in the cervical spine after 30 years of age in Saudi adult asymptomatic subjects.

Purpose: Spleen is enlarged in a variety of clinical conditions including infectious, infiltrative, immunologic and malignant states. Evaluation of splenic size is important in every physical examination of the abdomen by a physician. Determination of its size by palpation can be extremely inaccurate because spleen is never palpable till it is enlarged 2 to 3 times its own size. The accurate diagnosis of splenic enlargement is a matter of considerable importance as it is a useful guide for arriving at a diagnosis of the disease. It is therefore of utmost importance to resort to a mechanism that will give us an accurate estimation of the size of spleen. Aim of this work was to determine the normal range of spleen dimensions in average adult Saudi Arabian population and compare it with the published data. Methods: CT scans of 34 adult patients (male and female) aged between 20 -70 years, having no splenic disorders, were collected from department of radio-diagnosis King Khalid Hospital Al-Kharj, KSA. Splenic volume was measured by two methods-by volumetric software and the prolate ellipsoid formula. Results: The average splenic volume of all subjects was 161.42 ± 54.91 cm 3 with a range of 106 -319 cm 3 . The average splenic volume of males was 196.95 ± 48.70 cm 3 and that of female was 196.95 ± 26.97 cm 3 . Conclusions: These results provide normative data for evaluating patients with splenic enlargement.

The paranasal sinuses are hollowed, air-filled cavities surrounding the nasal cavity. Many pathological processes affect the sinuses, but inflammatory conditions are the commonest, even in asymptomatic patients who undergo head imaging for other indications showing one or more abnormalities of the sinuses. Our research aims to determine the prevalence of incidental paranasal sinuses abnormalities seen among patients who undergo head CT scanning. In addition, it provides baseline information for further investigations required. The study was designed to evaluate all patients who underwent head CT scanning for any reason unrelated to paranasal sinuses abnormalities. 1849 cases were selected and retrospectively analyzed from the elective and emergency CT in the last nine months, from August 2020 to April 2021. In order to meet the inclusion criteria, indications for imaging must not be sinus-related. The study was conducted on 1849 cases who had undergone head CT scans for pathology, 1204 (65%) were male and 645 (35%) were female. Abnormalities of the sinuses were found in about 617 (33%) of all patients, with a higher rate in males (22.23%) than females (11.14%). In addition, these abnormalities were found in younger patients at a higher rate than in middle and old ages 19.74%, 7.19%, and 6.44%, respectively. Our findings revealed that the prevalence of paranasal sinuses abnormalities in asymptomatic Saudi patients was high (33%). Most of the affected sinuses were the maxillary. The male patients were more affected than females in all findings.
