RESUMEN
Postpartum hemorrhage caused by a pseudoaneurysm of the uterine artery is suspected clinically in the case of abundant metrorrhagia. An ultrasound is performed, followed by further imaging modalities to confirm the diagnosis: CT scan, MRI, and angiography, the latter would also allow embolization. This is admittedly rare, however, since the pseudo aneurysm of the uterine artery is potentially fatal, it must be taken into account in the differential diagnosis of secondary postpartum hemorrhage, allowing adequate and rapid management. We report a case of pseudo aneurysm of the uterine artery, suspected clinically and confirmed by a CT scan, presenting as a secondary postpartum hemorrhage a few hours after delivery by cesarean section. It was eventually managed by embolization with excellent results several days after its onset when the cause was revealed. Angiographic embolization is an effective treatment for postpartum hemorrhage caused by pseudoaneurysm in stable patients. It should be considered before surgery in suitable cases.
RESUMEN
Primary dural lymphoma (PDL) constitutes a rare subgroup within central nervous system lymphomas, defined by its exclusive confinement to the dura mater, without a concurrent brain or systemic lymphatic involvement. This distinctive localization presents diagnostic challenges. In this report, we present a series of 3 cases where initial radiological presentations resembled meningiomas. We meticulously analyze key differentiating imaging characteristics, in CT, morphological MRI, and spectroscopy imaging. And show that recognizing and understanding these nuanced features are pivotal in enabling accurate differentiation of PDL and facilitating timely clinical intervention.
