Recombinant Tissue Plasminogen Activator Use in an Acute Stroke Patient With Tuberous Sclerosis

Tuberous sclerosis (TS) is an autosomal dominant disease known for over a century and recognized by characteristic hamartomatous lesions involving any organ. In this report, we are presenting a patient with TS who presented with acute embolic stroke and received tissue plasminogen activator (tPA) and had a mechanical thrombectomy (MT). She had a dramatic response without any hemorrhagic complications. She is a 68-year-old Caucasian woman with the past medical history of TS since childhood who presented to the hospital with symptoms of left middle cerebral artery (MCA) syndrome (right-sided weakness, sensory loss, right facial droop, aphasia, hemianopia, and dysarthria). National Institute of Health Stroke Scale (NIHSS) score was 19. Head computed tomography (CT) was negative for any acute abnormality except cortical tubers, subependymal ventricular calcification. CT angiography of the head and neck showed proximal occlusion of the left internal carotid artery. After ruling out all exclusion criteria, the patient received tPA and had an MT with complete reperfusion (thrombolysis in cerebral infarction (TICI) 3). Brain magnetic resonance imaging (MRI) showed an acute stroke in the multivessel territories (bilateral parietal cortices, the left lentiform nucleus, medial left temporal lobe, left thalamus, and right occipital lobe) suggestive of an embolic phenomenon and did not show any hemorrhagic complication. TS patients are at increased risk of intracerebral hemorrhage either in the setting of vascular malformation or due to hemorrhage into the subependymal giant cell astrocytoma. The best explanation for the latter could be secondary to elevated venous pressure from increased intracranial pressure. Fortunately, our TS patient who presented with acute ischemic stroke was within the window and received tPA and MT. The patient not only did not have any hemorrhagic side effects afterward but also had a significant improvement in her neurologic symptoms. To our best knowledge, this is the only case report of tPA administration in a TS patient. Moreover, we need more case reports to evaluate the safety of tPA in these patients.
