The study establishes that there is a relationship between presence of AG and IIH. Arachnoid granulation seems to act in a compensatory mechanism in patients with IIH.

COVID vaccination has begun in most of the countries. Older population and high-risk groups are prioritized for vaccination. Postvaccination imaging in cancer patients may show effects of the immune response to the vaccine. As such, it is important to know the timing and laterality of the vaccination as the reactive lymph nodes in the ipsilateral axilla can be seen on the imaging. We present a case of DOTATATE-avid nonpathologically enlarged lymph nodes in ipsilateral axilla and linear tracer uptake in the deltoid muscle on a patient imaged for a recent diagnosis of rectal neuroendocrine neoplasm.

Purpose To describe the incidence and patterns of the spinal injuries in the victims of physical IPV. Materials and methods With institutional review board (IRB) approval, we retrospectively reviewed patients referred to our institution's domestic violence intervention and prevention program with a diagnosis directly related to physical abuse between January 2013 and June 2018. Electronic health records and radiology reports were reviewed for all patients. Results A total of 21/688 (3%) IPV patients with 41 vertebral injuries were identified. The study population comprised of 19/21 (90%) females. Median age of the included patients was 43 years with a range of 21-72 years. All vertebral injuries were AO type A spinal injuries. Upper lumbar spine (L1 and L2) was the most common level of injury followed by upper to mid-thoracic spine. The reported mechanism of the injury was IPV in 8/21 (38.0%), fall in 8/21(38.0%), and incidental in 5/21 (24.0%). Ten out of 21 (48%) patients had concomitant injuries, most commonly to the craniofacial region 5/21 (23%). Psychiatry history was positive in 17/21 (81%), and substance abuse was positive in 15/21 (71%) of the patients. Conclusion Incidence of spinal injuries is relatively low in IPV with morphologic AO type A injury being the most common type of injury and the upper lumbar spine being the most common level of injury.

To evaluate the safety and diagnostic yield of CT-guided core-needle biopsy (CNB) versus fine-needle aspiration biopsy (FNAB) of lung nodules and masses in patients with hematologic malignancies (HMs). Materials and Methods:With institutional review board approval, 166 patients were retrospectively reviewed between 2007 and 2017 who were diagnosed with leukemia, lymphoma, or myelodysplastic syndromes (with or without hematopoietic stem cell transplant) and who underwent CT-guided FNAB and/or CNB of the lung. Patient medical records, pathologic reports, and interventional biopsy reports were reviewed.Results: In the study period, 166 patients underwent percutaneous CT-guided lung biopsy; 36% (60 of 166) of the procedures included CNB (CNB 1 FNAB and CNB only), whereas 64% (106 of 166) were FNAB only. In the CNB group, FNAB was also performed for 92% (55 of 60) of the patients before CNB; 13% (eight of 60) of patients in the CNB group were nondiagnostic versus 45% (48 of 106) of FNAB only (P , .0001). There was no statistically significant difference in the pulmonary complication rates, with 1.7% of CNB and 1.9% of FNAB only requiring chest tube placement (P = .7), 5% of CNB and 2.8% of FNAB only developing hemoptysis (P = .4), and 5% of CNB and 2% of FNAB only developing hemothorax (P = .3). A change in clinical management was observed in 51% of patients with diagnostic biopsies compared with 21% of patients with nondiagnostic biopsies (P = .0002). Conclusion:CT-guided CNB is an effective technique for performing lung biopsy in patients with HMs with higher diagnostic yield compared with FNAB, and a higher, although not a statistically significant, increased risk of bleeding complications and pneumothorax.
