ABSTRACT

Dural enhancement and thickening in imaging studies observed in acute mastoiditis patients is an uncommon phenomenon. It is infrequently seen in dural sinus thrombosis, and may be caused by infiltration of inflammatory cells and an increased number of thin-walled blood vessels. We present a three-year-old boy who presented with acute mastoiditis, complicated by subperiosteal abscess. Computerized tomography (CT) demonstrated subperiosteal abscess, and the child underwent mastoidectomy. Despite adequate treatment, symptoms worsened and neurological sequelae were suspected. CT and magnetic resonance imaging (MRI) studies demonstrated an atypical dural enhancement at the sigmoid perisinus and suboccipital abscess. The child underwent revision mastoidectomy and drainage of the abscess. Following the second procedure, resolution of symptoms was noted. Follow-up MRI did not demonstrate any dural pathologies.

ABSTRACT

Brain ischemia resulting from left atrial myxoma embolization has been well documented. In contrast, the link between the development of intracerebral hemorrhage and myxoma in these patients has little coverage in the literature. The main theory describing this relationship stems from the fact that cardiac myxoma cells metastasize to the brain's vessels, causing destruction of the arterial wall with subsequent formation of fusiform aneurysm and further intracranial bleeding. It is assumed that when a diagnosis of left atrial myxoma with neurologic manifestations is made, surgical resection should be performed without delay to prevent repeated tumor embolization; however, systemic anticoagulation treatment during cardiac surgery with cardiopulmonary bypass is not recommended immediately after intracerebral hemorrhage occurs because of the possibility of extending the infarct's size. We describe a patient with acute hemorrhagic brain infarction and an echocardiographically demonstrated left atrial myxoma that was surgically resected successfully in the acute phase after the onset of the neurologic symptoms.
