AbstractAbstract
[en] The purpose of this article is to review the spectrum of rare non-epithelial tumors of the prostate. This focused article will help the readers to understand the imaging findings of such rare entities attributed to their clinicopathological features. Radiologists must be familiar with the spectrum of non-epithelial tumors of the prostate, which helps to suggest alternate diagnosis other than adenocarcinoma, when imaging features are atypical. This is important because these tumors have different management approaches and prognoses when compared to adenocarcinoma of the prostate.

AbstractAbstract
[en] Non-traumatic urinary bladder emergencies are rare but critical diagnoses to make in an emergency setting. Acute urinary bladder pathologies require an accurate and timely diagnosis to ensure a favorable clinical outcome. Multidetector computed tomography (CT) is the imaging modality of choice for acute and emergent conditions affecting the urinary bladder. MRI is helpful as a problem-solving modality due to better soft tissue characterization and higher in-plane resolution. The purpose of this article is to illustrate the spectrum of urinary bladder emergencies, review the imaging findings, and briefly describe the role of imaging in the evaluation of such patients. Although there are a few cases of bladder emergencies been reported separately, the literature summarizing the spectrum is lacking. The objective of this article is to review the imaging of acute emergencies involving urinary bladder that will help us to think beyond non-specific conclusion in an emergency setting. For the sake of focused discussion, traumatic bladder emergencies will be excluded in this review. In the era of highly image reliant clinical practice, radiologists must be familiar with the diagnostic strategy to approach these entities.

AbstractAbstract
[en] Highlights: •This was a prospective study to evaluate role of spinal ultrasound (US) in 60 infants (<6 months of age) with clinically suspected meningitis. •On ultrasound examination, we evaluated echogenicity and /or trabeculations in the posterior subarachnoid space and spinal cord pulsations. •Results of spinal US were evaluated in correlation with cerebrospinal fluid analysis. •Results of our study show presence of echogenicity/trabeculations in posterior subarachnoid space or abnormal pulsations of spinal cord and nerve roots are significantly associated with meningitis with a high specificity and positive predictive value in its diagnosis. •Spinal ultrasound can be used as a radiation free imaging modality to detect meningitis. -- Abstract: Background: Spinal ultrasound (US) can detect changes in CSF echogenicity and decreased cord pulsations which reflect the inflammatory changes in meningitis. Till date, there is no published data about the prospective accuracy of spinal US in meningitis. Objective: To assess accuracy of spinal US in diagnosis of meningitis in infants younger than 6 months. Methods: This was an institute ethics committee approved prospective study carried out in infants less than 6 months of age with clinical suspicion of meningitis who presented to pediatric emergency unit. 60 infants each in study and control group were enrolled. US of thoraco-lumbar spine were performed prior to lumbar puncture in all cases. We looked for the presence of echogenicity or trabeculations in posterior subarachnoid space and for presence or absence of spinal cord and nerve root pulsations on real time ultrasound. The results of spinal US were evaluated in correlation with cerebrospinal fluid analysis. Follow up ultrasounds were done in infants who showed abnormal findings after the initiation of treatment and findings compared with initial results. Results: The study group comprised of 40 boys and 20 girls with mean age of 47.85 days. The control group comprised of 36 boys and 24 girls with a mean age of 60.53 days. 34/60 cases in study group had CSF findings suggestive of meningitis. Based on imaging parameters, spinal US had sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 67.16%, 92.3%, 93.1% and 74.64%, respectively. Chi-square test showed a statistically significant association between infants with meningitis and positive US findings (p < 0.05). Conclusion: Spinal US findings of CSF debris, septations and decreased spinal cord pulsations can be seen in infants with meningitis
