Uncommon Complication

Cerebral vasospasm is an uncommon complication following transsphenoidal surgery (TSS) of a pituitary adenoma. Therefore, neither its physiopathology nor its management are clear. We present a case of vasospasm after TSS and we discuss about its etiology and treatment. A 52-year-old woman presented with hirsutism, without neurologic symptoms. A MRI showed a pituitary macroadenoma. The patient underwent an endoscopic transsphenoidal approach. Post-operative CT scan revealed an extensive subarachnoid haemorrhage (SAH). On postoperative 7th day, she developed an abrupt mixed aphasia. An urgent arteriography showed left middle cerebral artery vasospasm, so intra-arterial nimodipine was administered. After that, vasospasm disappeared and the patient recovered completely. The key to successful management of this rare complication is a high index of suspicion. The presence of postoperative SAH seems to definitely contribute to its apparition. Therefore, treatment in concordance with protocols for vasospasm due to aneurysmal SAH is recommended.

The aim of this case report was to present a rare case of peripartum cardiomyopathy (PPCM) in an adolescent primigravida, and discuss its presentation and successful management. PPCM is a relatively rare yet life threatening cardiac complication of pregnancy. It often remains undiagnosed as its symptoms may simulate the physiological symptoms of pregnancy and peripartum period. An early diagnosis is crucial for improving survival. We herein report an unusual case of PPCM in an young and otherwise healthy primigravida. A 19-year-old primigravida presented at 33 weeks of gestation with, severe pre-eclampsia with dyspnea, cough and discomfort in the chest. Based on clinical findings and ECG, the echocardiography was done, and a definitive diagnosis of PPCM was made. The patient was managed for heart failure and preeclampsia by a multidisciplinary team. Emergency cesarean was done for obstetric indication and patient was managed conservatively in intensive care unit. Patient improved clinically and was discharged at day 10. Peripartum cardiomyopathy though typically associates with advanced maternal age can occur in very young women as well. A high index of suspicion for PPCM is recommended on a background of `severe preeclampsia with breathlessness. Timely echocardiography for diagnosis, and a multidisciplinary team approach are a key to successful management. Clinical significance of the study was to shed new light on the unusual presentation of PPCM and to contribute to the existing knowledge of PPCM.

A 75 year-old male developed features of an acute stroke following bubble contrast echocardiography, which was shown on emergent computed tomography scanning to be a result of cerebral arterial gas embolism (CAGE) to the left middle cerebral artery. Ischaemic stroke symptoms have previously been reported as a rare complication of bubble contrast echocardiography. Radiologically proven CAGE from bubble contrast echocardiography had not been reported at the time this case occurred. Immediate provision of 100% oxygen and administration of hyperbaric oxygen are recommended treatments for CAGE and were associated with a substantial recovery for this patient.

Cerebral infarction is a rare complication of pituitary apoplexy, which can result in significant morbidity if not treated on time. Pituitary apoplexy mostly occurs in pre-existing adenoma, which can remain undiagnosed until symptoms arise. Here, we present a case of a 26-year-old man with undiagnosed acromegaly who presented with left retro-orbital pain, diminished vision of the left eye, and right hemiparesis. Neuroimaging revealed large hemorrhagic sellar mass and ischemic infarction in the left middle cerebral artery territory. Emergency transcranial tumor excision was done, which resulted in significant neurological recovery.

Objective: Takayasu arteritis is a rare granulomatous chronic vasculitis that affects the aorta and its main branches. Neurologic manifestations can accompany the disease; however, there is no study on neuroimaging in children with Takayasu arteritis. Therefore, we aimed to evaluate cranial magnetic resonance imaging (MRI) in pediatric Takayasu arteritis patients. Materials and Methods: Demographic, clinical, and laboratory data were obtained retrospectively. Results: The study included 15 pediatric Takayasu arteritis patients. All patients presented with constitutional symptoms. Additionally, 6 patients suffered from headache, 2 had syncope, 1 had loss of consciousness, and 1 had convulsion. All patients underwent cranial and diffusion MRI a median 12 months after diagnosis. Cranial MRI findings were normal in 12 patients, whereas 3 patients had abnormal findings, as follows: stenosis in the M1 and M2 segments of the left middle cerebral artery (n = 1); diffuse thinning of the right internal carotid, middle cerebral, and right vertebral and basilar artery (n = 1); as a sequela, areas of focal gliosis in both the lateral ventricular and posterior periventricular regions (n = 1). Among these 3 patients, 1 had no neurologic complaints. Conclusion: Abnormal MRI findings can be observed in pediatric Takayasu arteritis patients, even those that are asymptomatic; therefore, clinicians should carefully evaluate neurologic involvement in all pediatric Takayasu arteritis patients.

Background Post-stroke cognitive impairment can occur after damage to various brain regions, and cognitive deficits depend on infarct location. The Mini-Mental State Examination (MMSE) is still widely used to assess post-stroke cognition, but it has been criticized for capturing only certain cognitive deficits. Along these lines, it might be hypothesized that cognitive deficits as measured with the MMSE primarily involve certain infarct locations. Aims This comprehensive lesion-symptom mapping study aimed to determine which acute infarct locations are associated with post-stroke cognitive impairment on the MMSE. Methods We examined associations between impairment on the MMSE (<5th percentile; normative data) and infarct location in 1198 patients (age 67 ± 12 years, 43% female) with acute ischemic stroke using voxel-based lesion-symptom mapping. As a frame of reference, infarct patterns associated with impairments in individual cognitive domains were determined, based on a more detailed neuropsychological assessment. Results Impairment on the MMSE was present in 420 patients (35%). Large voxel clusters in the left middle cerebral artery territory and thalamus were significantly (p < 0.01) associated with cognitive impairment on the MMSE, with highest odds ratios (>15) in the thalamus and superior temporal gyrus. In comparison, domain-specific impairments were related to various infarct patterns across both hemispheres including the left medial temporal lobe (verbal memory) and right parietal lobe (visuospatial functioning). Conclusions Our findings indicate that post-stroke cognitive impairment on the MMSE primarily relates to infarct locations in the left middle cerebral artery territory. The MMSE is apparently less sensitive to cognitive deficits that specifically relate to other locations.

Introduction: Intraorbital abscess is a rare complication of rhinosinusitis that affects most commonly the pediatric population. It is thought to be caused by direct extension or venous spread of infections from contiguous sites and can lead to life-threatening complications, like permanent visual loss and cerebral abscesses. Objectives: Intraorbital abscess is a rare condition that requires prompt diagnosis and treatment to avoid serious complications. Our objectives are to provide an overview of this rare disease process and its management including our successful treatment experience. Case Description: We present a 2 case report of a 13-year-old pediatric male and a 66-year-old male with history of chronic sinusitis who presented with a right intraorbital abscess successfully treated with external drainage with decompression of the orbit. Conclusion: When intraorbital abscess is encountered, a high index of suspicion is needed to allow prompt and accurate diagnosis for this infrequent condition. Timely surgical drainage of the abscess is needed to prevent the development of fatal complications.

Arterial Thrombolysis

Abstract OBJECTIVE AND IMPORTANCE Intra-arterial thrombolysis has been demonstrated to improve recanalization and outcomes among patients with acute ischemic stroke. However, thrombolytic agents have limited effectiveness and are associated with a significant risk of bleeding. Bivalirudin is a direct thrombin inhibitor that has been demonstrated in the cardiology literature to have a more favorable efficacy and bleeding profile than other antithrombotic medications. We report the use of bivalirudin during endovascular treatment of acute stroke, when hemorrhagic complications are not uncommon. CLINICAL PRESENTATION A 71-year-old woman with atrial fibrillation presented with right hemiparesis and aphasia and was found to have a National Institutes of Health Stroke Scale score of 10. Computed tomographic scans revealed no evidence of intracranial hemorrhage, aneurysm, or ischemic stroke. Cerebral angiography revealed thromboembolic occlusion of the superior division of the left middle cerebral artery. INTERVENTION For anticoagulation, a loading dose of bivalirudin was intravenously administered before the interventional procedure, followed by continuous infusion. Attempts to remove the clot with an endovascular snare failed to induce recanalization of the vessel. Bivalirudin was then administered intra-arterially. Immediate postprocedural angiography demonstrated restoration of flow in the left middle cerebral artery. Repeat computed tomographic scans demonstrated no intracranial hemorrhage. The patient's hemiparesis and aphasia were nearly resolved and her National Institutes of Health Stroke Scale score was 2 at the time of her discharge 5 days later. CONCLUSION To our knowledge, this is the first report of the use of bivalirudin for treatment of acute ischemic stroke. Bivalirudin may be a useful agent for intravenous anticoagulation and intra-arterial thrombolysis in this setting.

✓ An 11-month-old boy was admitted for evaluation of drowsiness, vomiting, and convulsions. Computerized tomography showed subarachnoid blood in the left sylvian fissure and a small intracerebral hematoma in the temporal lobe. Angiography revealed several aneurysms of the left middle cerebral artery (MCA). During surgery, 13 aneurysms were found arising from one main branch of the left MCA, and this segment of the MCA was trapped. Somatosensory evoked potentials did not show any change during surgery. The diseased arterial segment was examined histologically and the pathogenetic aspects of the case are discussed. Control angiography 6 months later excluded systemic disease or other aneurysms. The rarity of such lesions in childhood and their successful surgical treatment are discussed briefly.
