Because of the close anatomical relationship between the maxillary sinus and the adjacent dental region, determining the primary site of cysts in these regions can be a diagnostic dilemma. In this article, two cases with similar radiological findings are presented. These cases had lesions involving the maxillary sinus and the adjacent alveolar process; the lesions were surrounded with egg-shaped, linear opacities. Diagnoses of a residual radicular cyst in one case and a calcified mucocoele (which is very rare) in the other case were predicted with the help of radiological findings and were confirmed surgically and histopathologically.

Doppler US is an effective tool to detect tCBF volume decrease in chronic cigarette smokers. Although minimal, this decrease, as demonstrated here in asymptomatic, healthy people, might be critical in patients with subclinical cerebral arterial insufficiency. © 2017 Wiley Periodicals, Inc.

The objective of this study is to assess the hepatic/renal and splenic/renal echointensity ratios in ultrasonography in patients with and without diabetic nephropathy. This retrospective study included patients with diabetes mellitus who underwent ultrasound examinations at our hospital between January 2023 and May 2023. Ultrasound examinations done with renal cortical echogenicity and cortico-medullary differentiation by using B-mode ultrasonography. The hepatic/renal and splenic/renal echo intensity ratios were compared among study groups (diabetic patients with diabetic nephropathy and without nephropathy). The diabetic nephropathy group exhibited significantly higher right renal echointensity and left renal echointensity compared to the non-nephropathic group. Additionally, the splenic/renal echointensity ratio and hepatic/renal echointensity ratio were significantly lower in the diabetic nephropathy group. Urinary microalbumin levels was significantly correlated with Right renal echointensity (r=0.65, p<0.001) and Left renal echointensity (r=0.69, p<0.001). There was also a significant inverse correlation between urinary albumin and splenic/renal echointensity ratio (r=-0.58, p<0.001). Ultrasonography, specifically the assessment of hepatic/renal and splenic/renal echointensity ratios, shows promise as a non-invasive and cost-effective method for evaluating morphological changes in the kidneys in patients with diabetic nephropathy. These findings suggest that ultrasonography can be a valuable tool for monitoring the progression of diabetic nephropathy and contributing to its early detection and management.

Knee osteoarthritis is a very common joint disease in the community. However, some meniscus lesions are asymptomatic. Studies show that a significant number of individuals with knee pain without radiographic osteoarthritis findings show meniscus injury on magnetic resonance imaging (MRI). Our study aimed to evaluate the relationship between meniscus lesions and the presence of radiographic knee osteoarthritis in individuals over 50 years of age with knee pain complaints. Methods: Radiographic and MRI results of two hundred and forty patients who applied to our hospital with the complaint of knee pain between August 2018 and January 2020 were analyzed. Radiographic grading for knee osteoarthritis was performed using the Kellgren Lawrence scale. Classification of meniscus lesions in MRI was made as per the criteria defined by the British Knee Meniscus Surgery Association. Intergroup results were evaluated statistically. Results: Osteoarthritis was detected in 110 (45.8%) of 240 knee radiographs. In 78.3% of all cases, meniscus lesions were detected in 96.4% of those with osteoarthritis and 63% of those without osteoarthritis. In patients with osteoarthritis, the prevalence of surgically targeted and possible target lesions was found to be significantly higher than those with no arthritis findings. Conclusions: According to our study results, meniscus lesions were found quite common in individuals with knee pain, especially those with osteoarthritis. Particularly in patients with radiographic osteoarthritis findings, surgical targets and possible target meniscus lesions were more common than those without osteoarthritis findings. Therefore, MRI, in addition to direct radiography, should not be overlooked when determining treatment.
