Brain arteriovenous malformations (AVM) are abnormal vascular connection between arteries (pial vessels) and veins via a nidus of vessels through which shunting of blood occurs in the absence of true capillary bed. When intracranial AVMs are encountered at cross-sectional imaging, other diagnoses like malignant dural arteriovenous stulas, and moyamoya disease must also be considered. Secondary effects such as gliosis, neurologic decits, venous congestion, hydrocephalus should be included in the radiology report. Imaging ndings inuence the clinical management by neurosurgeons.

Cerebral artery fenestrations are rare anatomical variants usually detected incidentally on cross-sectional imaging or cerebral angiography. Although considered benign findings, many reports have described their association with vascular abnormalities such as aneurysms or arteriovenous malformations, and to a lesser extent with ischemic or hemorrhagic complications. We report a case of middle cerebral artery fenestration associated with subarachnoid hemorrhage and middle cerebral artery thrombosis. To our knowledge, there has been no prior report of middle cerebral artery fenestration with a similar presentation.

Cranial Metastasis

Cranial metastases from hepatocellular carcinoma (HCC) has been seldom reported. Reported herein is the case of a painless parietal bone mass as an initial presentation of HCC in a 63-year-old female patient who was subsequently diagnosed to have HCV related cirrhosis. The biopsy from cranial lesion was confirmatory of HCC on immunohistochemistry. The patient had no known history of chronic liver disease. The presented diagnosis was made through detailed history, laboratory parameters and cross sectional imaging.

The increasing availability of cross-sectional imaging, incredibly magnetic resonance imaging, detects ndings in the patient's scan unrelated to the reason the scan is initially acquired. These ndings refer to the so-called incidental ndings mentioned in the radiology report as "Note made of" without any good impression about their clinical signicance or further management. This type of report leads to anxiety among patients. The radiologist is the rst person to encounter these incidental ndings. Therefore, it is an essential duty of the radiologist to communicate to the clinician about the signicance and urgency/non-urgency of these ndings so that clinicians can decide timely appropriate management. Therefore, this review discusses the prevalence and spectrum of these incidental ndings and the available guidelines for their management.

Aggressive Variant

AbstractAngiomyxomas are soft tissue tumors that are exceedingly rare with very few cases described in literature. They are classified into a less aggressive superficial variant and a deeper aggressive variant commonly called aggressive angiomyxomas (AA). The cross-sectional imaging, particularly magnetic resonance imaging (MRI), plays an essential role in the diagnosis and management of AA. We report a rare case of Aggressive angiomyxoma in a 28-year-old female.

Transcatheter aortic valve replacement (TAVR) as well as thoracic and abdominal endovascular aortic repair (TEVAR and EVAR) rely on accurate pre- and postprocedural imaging. This review article discusses the application of imaging, including preprocedural assessment and measurements as well as postprocedural imaging of complications. Furthermore, the exciting perspective of computational fluid dynamics (CFD) based on cross-sectional imaging is presented. TAVR is a minimally invasive alternative for treatment of aortic valve stenosis in patients with high age and multiple comorbidities who cannot undergo traditional open surgical repair. Given the lack of direct visualization during the procedure, pre- and peri-procedural imaging forms an essential part of the intervention. Computed tomography angiography (CTA) is the imaging modality of choice for preprocedural planning. Routine postprocedural follow-up is performed by echocardiography to confirm treatment success and detect complications. EVAR and TEVAR are minimally invasive alternatives to open surgical repair of aortic pathologies. CTA constitutes the preferred imaging modality for both preoperative planning and postoperative follow-up including detection of endoleaks. Magnetic resonance imaging is an excellent alternative to CT for postoperative follow-up, and is especially beneficial for younger patients given the lack of radiation. Ultrasound is applied in screening and postoperative follow-up of abdominal aortic aneurysms, but cross-sectional imaging is required once abnormalities are detected. Contrast-enhanced ultrasound may be as sensitive as CTA in detecting endoleaks.

Introduction: Prostate cancer (PCa) staging is an integral part in the management of prostate cancer. The gold standard for diagnosing lymph node invasion is a surgical lymphadenectomy, with no superior imaging modality available at the clinician’s disposal. Our aim in this study is to identify if a pre-biopsy multiparametric MRI (mpMRI) can provide enough information about pelvic lymph nodes in intermediate and high risk PCa patients, and whether it can substitute further cross sectional imaging (CSI) modalities of the abdomen and pelvis in these risk categories. Methods: Patients with intermediate and high risk prostate cancer were collected between January 2015 and June 2019, while excluding patients who did not undergo a pre-biopsy mpMRI or a CSI. Date regarding biopsy result, PSA, MRI results, CSI imaging results were collected. Using Statistical Package for the Social Sciences (SPSS) version 24.0, statistical analysis was conducted using the Cohen’s Kappa agreement for comparison of mpMRI with CSI. McNemar’s test and receiver operator curve (ROC) curve were used for comparison of sensitivity of both tests when comparing to the gold standard of lymphadenectomy. Results: A total of 143 patients fit the inclusion criteria. We further stratified our patients into according to PSA level and Gleason score. Overall, agreement between mpMRI and all CSI was 0.857. When stratifying patients based on Gleason score and PSA, the higher the grade or PSA, the higher agreement between mpMRI and CSI. The sensitivity of mpMRI (73.7%) is similar to CSI (68.4%). When comparing CSI sensitivity to that of mpMRI, no significant difference was present by utilizing the McNemar test and very similar receiver operating characteristic curve. Conclusion: A pre-biopsy mpMRI can potentially substitute further cross sectional imaging in our cohort of patients. However, larger prospective studies are needed to confirm our findings.
