Case Reports
Thyroid Hemorrhage Causing Airway Obstruction After Intravenous Thrombolysis for Acute Ischemic Stroke.
There are several life-threatening complications associated with intravenous thrombolysis after acute ischemic stroke such as symptomatic intracerebral hemorrhage, orolingual angioedema, or less frequent, bleedings of the mucosa or ecchymosis. Aside from these known critical incidents, rare and unfamiliar complications may be even more challenging, as they are unexpected and may mimic events that appear more frequently. We report a rare and unusual acute complication of intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) (0.9 mg/kg) administered for acute ischemic stroke. ⋯ Acute airway obstruction with respiratory failure due to thyroidal hemorrhage after intravenous thrombolysis is an important life-threatening complication, mimicking an anaphylactic reaction or a more frequent orolingual angioedema.

Posterior reversible encephalopathy syndrome (PRES) is a largely reversible disease with long-term favorable outcome. A minority of patients, however, may develop progressive cerebral edema and ischemia resulting in severe disability or death. We report a case of severe intracranial hypertension associated with PRES that was successfully treated according to intracranial pressure (ICP)- and cerebral perfusion pressure (CPP)-driven therapy. ⋯ The decision to undertake ICP monitoring in medical conditions in which no clear recommendations exist greatly relies on physicians' judgment. This case suggests that ICP monitoring may be considered in the setting of acute PRES among selected patients, when severe intracranial hypertension is suspected, provided that a multidisciplinary team of neurocritical care specialists is readily available.

Recovery is common after subarachnoid hemorrhage (SAH), even in patients who are severely disabled at hospital discharge. Little is known about predictors of late recovery in such patients, even though such knowledge may influence treatment decisions. We hypothesized that cerebral infarction volume would be associated with 3 months outcomes in patients who are severely disabled at 14 days. ⋯ After SAH, even with severe neurological injury at 14 days, good recovery is frequent and is associated with lower infarction volume. These data may help clinicians inform surrogate decision makers as they plan the future care of such severely disabled patients.

Comparative Study
Early Major Worsening in Ischemic Stroke: Predictors and Outcome.
We aimed to investigate the characteristics and outcome of patients suffering early major worsening (EMW) after acute ischemic stroke (AIS) and assess the parameters associated with it. ⋯ Worsening of ≥8 points in the NIHSS score during the first 24 h in AIS patients is related to cervical artery dissection and hemorrhagic transformation. It justifies urgent repeat parenchymal and arterial imaging. Both conditions may be influenced by targeted interventions in the acute phase of stroke.

Comparative Study
Prediction of Poor Outcome in Cerebellar Infarction by Diffusion MRI.
Identification of patients with posterior fossa infarction at risk for neurological deterioration remains a challenge. MRI-based assessments of MCA infarction can predict poor outcome. Similar quantitative imaging measures after cerebellar stroke have not been studied. We tested the hypothesis that MRI-based volumetric assessment of cerebellar infarcts can provide reliable information for the prediction of poor outcome. ⋯ Quantitative volumetric measurement predicts poor outcome of cerebellar stroke patients, even when controlling for age and NIHSS. Quantitative analysis of diffusion MRI may assist in identification of patients with cerebellar stroke at highest risk of neurological deterioration. Prospective validation is warranted.
