We report two cases of young patients with lacunar stroke who demonstrated multiple microbleeds (MBs) a long period after cranial irradiation. Case 1: a 44-year-old man developed dysarthria and left hemiparesis from a day before admission. Magnetic resonance imaging showed an acute lacunar infract in the right corona radiata. Case 2: a 28-year-old woman was admitted due to dysarthria and right hemiparesis. An acute lacunar infract was detected in the left corona radiata. T2* WI revealed multiple MBs in the region corresponding to the irradiation in both patients. Since these patients had no vascular risk factors except for smoking habit in the former one and dyslipidemia in the latter one. We speculated that lacunar stroke and MBs had resulted from past cranial irradiation. In addition to accelerated atherosclerosis of the large vessels, small vessel disease should be noted as an important long-term complication after cranial irradiation.

A rare case of bilateral ventrolateral pontine infarction in a 70-year-old man who developed progressive dysarthria and bilateral sensory disturbance is reported with literature review. He had been diagnosed with hypertension, dyslipidemia, and impaired glucose tolerance 10 years earlier. Ten days before admission, he was aware of the difficulty in walking and speaking, which gradually worsened. On admission he showed bilateral thermal hypoalgesia of face and lower extremities, dysarthria, dysphagia, and ataxic gait. High resolution three-dimensional MRI revealed bilateral ventrolateral pontine infarction with a large atherosclerotic plaque in the ventral side of the basilar artery, which led to a diagnosis of atherothrombotic brain infarction. The atherosclerotic plaque in the basilar artery was thought to be responsible for simultaneous occlusion of the bilateral short circumflex arteries of the pons.

A 76-year-old man with a history of arterial hypertension, obstructive sleep apnea, dyslipidemia, family history of cardiovascular events, prestroke and overweight presented 90 minutes after acute onset of right-sided sensorimotor hemiparesis, hemiataxia and dysarthria (National Institutes of Health Stroke Scale (NIHSS) 9/42). Magnetic resonance imaging (MRI) revealed a pontine ischemia and MR angiography showed a thrombus in the middle to distal portion of the basilar artery. Owing to the location, an occlusion of one lumen of a fenestrated basilar artery was suspected. Fearing the risk of peripheral dislocation, intravenous thrombolysis was withheld after an interdisciplinary discussion and direct endovascular thrombectomy (Solitaire stent retriever) was successfully performed by passing the stent retriever specifically through the affected lumen and between the thrombus and the vascular wall, which would normally be avoided. Angiography after complete reperfusion (Thrombolysis in Cerebral Infarction grade 3) confirmed a fenestration in the middle to distal portion of the basilar artery where the thrombus was initially located (blue and green arrow). Follow-up MRI after 24 hours showed only minimal ischemic damage in the left pontine area, and the patient was discharged home with ambulatory physiotherapy for residual minimal gait disturbance (NIHSS 0).

There are few clinical reports of elderly patients with paradoxical embolism in the current literature. Herein, we describe the case of a nonagenarian patient with paradoxical embolism of stroke-related patent foramen ovale (PFO). A 95-year-old woman was admitted to our hospital because of dysarthria. Her medical history included cerebral infarction, hypertension, and dyslipidemia. Magnetic resonance imaging performed in the emergency room revealed cerebral infarction of the left temporal lobe. After hospitalization in the neurosurgery department, we performed further clinical investigations to diagnose the type of stroke. There was no significant stenosis with plaque of the carotid and cerebral arteries, and there were no sources of cardiac embolism or an episode of atrial arrhythmia. Transesophageal echocardiography (TEE) showed PFO with separation and the Eustachian valve. In addition, spontaneous bidirectional shunt flow through the PFO was detected by TEE with the patient at rest. Ultrasonography of the leg vein revealed a thrombus in the deep vein. Therefore, she was diagnosed as having paradoxical embolism of stroke-related PFO and prescribed a direct oral anticoagulant (DOAC). This very rare case in which stroke-related PFO was diagnosed in a nonagenarian patient demonstrates that PFO is the cause of paradoxical embolism of stroke regardless of age.
