Objectives: To describe radiographic imaging findings and disease course in admitted Coronavirus disease 2019 (COVID-19) patients. Methods: This retrospective study was carried in the Radiology Department, King Fahad Military Medical Complex, Dhahran between March to August 2020 (6 months). All laboratory confirmed COVID-19 admitted cases were evaluated for their symptoms, duration of hospital stays (in a ward or intensive care unit [ICU]), and imaging findings (ground-glass opacity [GGO], air-space shadowing/consolidation, and others such as atelectasis, reticulation, peribronchovascular thickening, lymphadenopathy and pleural effusion) on chest radiograph (CXR) and computed tomography (CT) studies. Cavitation, nodularity, bronchiectasis, and embolism detected on CT scans were considered as complications. Disease course in terms of recovery (radiographic regression or resolution of findings), worsening (shifting from ward to ICU), and unfavorable outcome (persistent ICU stay or death) were recorded. Imaging findings were interpreted by 2 experienced radiologists and consensus reporting was made. Chi-square test was used to determine association. Results: Out of 106 patients, majority were males (n=82, 77.4%). Forty-six patients (43.3%) had abnormal imaging with mostly peripheral GGO (56.5%), followed by consolidations (34.7%), and others (26%). Complications were detected in 6 ICU patients. All patients with unfavorable outcomes were above 60 years having comorbidities or complications ( p less than 0.0005). Fatality rate was calculated as 2.8. Conclusion: Coronavirus disease 2019 is seen mostly affecting males, with peripheral opacities as common imaging findings. Elderly patients with co-morbidities may show unfavorable outcomes.

Objectives: To highlight and compare spectrum of hysterosalpingography (HSG) findings in primary and secondary infertility patients. Methods : This retrospective record-based cross-sectional study was performed in the Radiology Department, King Fahad Military Medical City, Dhahran, Kingdom of Saudi Arabia between August 2016 and 2018. All patients (N=303) who underwent successful HSGs were included, and grouped under primary and secondary infertility cases. Patients with failed, limited or incomplete studies were excluded. Imaging findings were documented as N (Normal) or Ab (Abnormal). Abnormal HSG findings were further categorized as: C=congenital malformation, I=infection or inflammation, S=surgery, T=tumor or tear. Abnormal findings were confirmed on further imaging or intervention. Chi-square test was used to determine any association of HSG findings with type of infertility, and p -value less than 0.05 was considered significant. Results : Of the 303 patients, 166 patients (54.8%) had primary infertility while the rest had secondary infertility. Abnormal studies were found in less than one-third of patients (n=93, 30.7%). Primary infertility patients exhibited more congenital (C) malformations, while surgery (S) was seen more in secondary infertility patients ( p =0.01). Conclusion : Congenital malformations are commonly found abnormalities on HSGs in primary infertility patients, while surgery related findings are seen in secondary infertility cases.

Objective To evaluate the use of duplex carotid artery screening in patients undergoing coronary artery bypass graft (CABG). Methods This descriptive, observational study was conducted in Radiology Department at King Fahad Military Medical Complex, Dhahran, Kingdom of Saudi Arabia from April 2015-2018. All Saudi patients (n=178) who underwent duplex carotid sonography prior to CABG were retrospectively reviewed for essential morphologic and hemodynamic information to estimate severity of extra-cranial internal carotid artery (ICA) stenosis. Patients with combined CABG and cardiac surgery, and those with limited carotid studies were excluded. Advancing age (65 years or above), gender, smoking, obesity, diabetes (DM), hypertension (HTN), dyslipidemia, coronary vessel disease, cardiac disease and previous stroke were recorded. Post-coronary artery bypass graft neurologic event (namely, transient ischemic attack [TIA] or stroke) was recorded. Chi-square test was used to determine association of stenosis degree with post-CABG neurologic event. Results One hundred twenty eight patients (72%) were having ICA disease, while significant carotid artery stenosis (>70%) was seen in 11 patients (6.2%). Post-coronary artery bypass graft neurologic event was seen in 4.5% of patients. Advancing age, significant ICA stenosis and multi-vessel coronary disease were seen associated with a post-CABG event. Conclusion Significant ICA stenosis on duplex screening in elderly patients with multi-vessel coronary artery disease or certain risk factors may predict post-CABG stroke.

We are reporting a case of interhemispheric-pericallosal lipoma, associated with bilateral small lateral ventricle choroid plexuses and third ventricle lipoma as well as partial agenesis of splenium of corpus callosum. Presentation in our case does not correspond to existing classification of pericallosal lipoma and as it is very rare, we are presenting it as a case report. Intracranial lipoma itself is a very rare anomaly and account for 0.06% to 0.46%. It represents a group of developmental abnormality of brain parenchyma that occur during embryogenesis, and it is located more frequently (about 50%) in the pericallosal cistern and may extend into one or both lateral ventricles. Pericallosal lipoma can also be associated with varying degree of callosal anomalies.
