A rare complication of transbronchoscopic lung biopsy, namely a cerebral air embolism, is presented. The course of events following the embolic episode in the form of a fall in blood pressure, bradycardia and convulsions is documented, as is the presence of an air emboli on the CT scan of the brain with subsequent resorption of the emboli on the follow‐up scan. The salient features of the case are the rarity of the complication and the excellent temporal depiction of imaging findings on CT scan demonstrated as resorption of air emboli and subsequent watershed territory infarcts. 相似文献

The deletion of the long arm of chromosome 6 is the most common cytogenetic abnormality in Waldenstrom's macroglobulinemia (WM), but its prognostic significance is unclear. We investigated 77 patients with WM by interphase cytoplasmic immunoglobulin M fluorescence in situ hybridization (cIgM-FISH) and correlated the 6q status with the patients' clinical features and survival. cIg-FISH detected hemizygous 6q deletions in 32 patients (41.6%). The 6q deletions were correlated with higher C-reactive protein levels (P = .02) and CD23 expression (P = .03) but not with other clinical laboratory features of WM. There was no significant difference in time to the initial treatment between deleted and non-deleted groups (median, 5.6 months vs. 2.6 months; P = .46), or overall survivals in patients with and without del (6q) (163 months vs. not reached; P = .83). Our study confirms that the 6q deletion is a frequent event, but it does not appear to affect the clinical outcome of WM. 相似文献

Medulloepithelioma is an uncommon tumour. These tumours most commonly arise in the brain and spinal cord; however, they also may arise from the optic nerve. We, herein, report a rare case of malignant non‐teratoid medulloepithelioma of the optic nerve with intraocular extension. 相似文献

Immunoenrichment-based matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS), termed MASS-FIX, offers several advantages over immunofixation for the detection and isotyping of serum monoclonal protein, including superior sensitivity and specificity, the ability to differentiate therapeutic monoclonal antibodies, and the rapid identification of light chain (LC) N-glycosylation. We identified 6315 patients with MASS-FIX performed at our institution since 2018. Of these, 4118 patients (65%) with a wide array of plasma cell disorders (PCD), including rare monoclonal gammopathies of clinical significance, had a positive MASS-FIX. Two-hundred twenty-one (5%) of the MASS-FIX positive patients had evidence of LC N-glycosylation, which was more commonly identified in IgM heavy chain isotype, kappa LC isotype, and in diagnoses of immunoglobulin light chain (AL) amyloidosis and cold agglutinin disease (CAD) compared to other PCD. This cross-sectional study describes the largest cohort of patients to undergo MASS-FIX in routine clinical practice. Our findings demonstrate the widespread utility of this assay, and confirm that LC N-glycosylation should prompt suspicion for AL amyloidosis and CAD in the appropriate clinical context.Subject terms: Myeloma, Translational research 相似文献
