We report the case of a 59-year-old obese female who developed an abdominal wall haematoma during administration of prophylactic clexane. Compared with the non-obese, the subcutaneous tissue of the obese is considered dysfunctional and has a different vascular structure and extra-cellular matrix composition. While the development of an abdominal wall haematoma is relatively uncommon, when they occur they can have fatal consequences. The altered subcutaneous tissue environment in the obese attenuates the normal external compression of an abdominal wall haematoma and as a result the obese are at greater risk of haemorrhage.
Cerebral amyloid angiopathy related inflammation (CAAri) is becoming increasingly recognised as a subset of cerebral amyloid angiopathy (CAA). CAAri generally presents with subacute cognitive decline, headaches, seizures, behavioral changes, and focal neurological deficits. We describe a patient who developed acute dysphasia and reversible cognitive decline due to probable CAAri. CT brain showed bilateral vasogenic edema in the cerebral hemispheres, predominantly involving the parietal and temporal lobes, left greater than right without enhancement. Magnetic resonance brain imaging showed extensive multifocal areas of subcortical white matter T2 hyperintensity in the frontal and temporal regions with associated mass effect, negligible enhancement, and multiple foci of microhemorrhage on susceptibility weighted imaging sequences consistent with a diagnosis of probable CAAri. She responded dramatically to a course of intravenous methylprednisolone followed by further immunosuppression with pulse intravenous cyclophosphamide. Her dysphasia resolved within 5 days of intravenous methylprednisolone therapy. Her MMSE improved from 11/30 at day 5 of admission to 28/30 at 6-month follow-up. The notable features of our case were the unusual CT findings, which were inconsistent with stroke and diagnostic utility of susceptibility-weighted magnetic resonance imaging in confirming the diagnosis which allowed for prompt institution of immunosuppression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
