Watershed Infarcts

A 69-year-old man was presented to our emergency department with acute onset of hemianopsia, aphasia and dizziness. He reported that while he was sitting in front of his computer at home, he had performed a bilateral self-massage of his carotid arteries when suddenly the symptoms occurred. A neurological examination revealed a hemianopsia with a visual field loss on the right side. In addition, a mild aphasic syndrome with agraphia and a word-finding disorder (National Institutes of Health Stroke Scale (NIHSS): 3 points) was diagnosed. The initial brain CT scan with CT angiography showed neither an intracerebral haemorrhage nor a cerebral infarction. Also, no occlusion or any signs of artery dissection or a flow relevant stenosis of the brain supplying arteries were found. After excluding other contraindications, an intravenous thrombolysis with weight-adapted alteplase was performed. The symptoms of the patient significantly improved in the short-term follow-up. Three days after admission no neurological deficits remained. The MRI of the brain revealed multifocal, small, left hemispherical strokes in the middle cerebral artery territory. In general, watershed infarcts after carotid sinus self-massage follow a rare ischaemic stroke mechanism. This case emphasises the importance of a detailed anamnestic evaluation to determine the aetiological classification of ischaemic stroke as well as educating patients’ (poststroke) behaviour.

We have described a 55-year-old woman with the anterior opercular syndrome (Foix-Chavany-Marie syndrome). The clinical presentation included acute onset of bilateral facial palsy and anarthria. Immediate MRI of the brain revealed acute ischemia in the right opercular region and sequelae after a previous infarction involving the left opercular region. The patient was treated with intravenous thrombolysis resulting in full recovery. The anterior opercular syndrome is rare, and the most common reason is sequential stroke. We emphasize the importance of recognizing this syndrome early, and in all cases, consulting a revascularization center immediately.

Case summary A 7-month-old Siberian cat was presented for investigation of acute onset multifocal neurological deficits. Neurological examination documented dull mental status and an ambulatory left hemiparesis. Serum biochemistry documented marked hyperglobulinaemia. MRI of the brain identified marked leptomeningeal contrast enhancement extending along the brainstem caudally to involve the cranial cervical spinal cord. MRI of the cervical spine further identified a subarachnoid diverticulum that extended from the level of the obex to the C2–C3 vertebrae. Cerebrospinal fluid quantitative RT-PCR was positive for the presence of feline coronavirus. Histopathology revealed pyogranulomatous meningitis and choroid plexitis, uveitis and nephritis. Relevance and novel information This article describes the first reported case of a subarachnoid diverticulum associated with feline infectious peritonitis.

Spontaneous renal artery dissection is a rare condition with an often non-specific presentation, resulting in a challenging diagnosis for clinicians. This is the case of a 39-year-old man who presented with an acute-onset right flank pain, mild neutrophilia and sterile urine. CT of abdomen and pelvis showed a patchy hypodense area in the right kidney originally thought to represent infection. He was treated as an atypical pyelonephritis with antibiotics and fluids. When his symptoms failed to improve, a diagnosis of renal infarction was considered and CT angiogram of the aorta revealed a spontaneous renal artery dissection. He was managed conservatively with systemic anticoagulation, antihypertensive treatment and analgesia and discharged home with resolution of his symptoms and normal renal function.

During a strangles outbreak within a herd of minature horses, a six week old foal developed acute onset clinical signs of sepsis and neurological deficits. The foal was euthanized and submitted for post-mortem at the Animal Health Laboratories, Guelph Ontario. Gross <em>post-mortem</em> examination noted severe bronchopneumonia, hypopyon of the right eye and a singular cerebellar peduncle abscess. Culture of the lungs and cerebellum produced a pure growth of <em>Streptococcus equi</em> ssp. <em>equi</em>. <em>Streptococcus equi</em> ssp. <em>equi</em>, the causative agent of equine strangles, produces an acute pyrexia, purulent lymphadenopathy of submandibular and retropharyngeal lymph nodes. Commonly, lymph node abscesses rupture and resolve without complication. Rarely, complications may include: dissemination of the bacteria with diffuse abscess formation, immune mediated disease (purpura haemorrhagica), rarely abscess formation within the central nervous system (CNS) can occur. These can be managed medically with appropriate antibiotics and drugs to reduce intra-cranial pressure, however surgical drainage and debulking of the abscess has been attempted successfully in a few cases.

Trans Cranial Doppler

This is the first reported attempt to examine the emboliogenic potential of cardiac myxoma in patients with acute stroke through the monitoring of microembolic signals (MES) by transcranial doppler. A 43-year old woman was brought to the emergency department because of acute onset of generalized tonic-clonic seizures and left hemiplegia. A CT scan of the brain demonstrated a large acute infraction in the territory of the right middle cerebral artery (MCA) and another smaller one in the territory of the posterior cerebral artery on the same side. Trans-cranial doppler (TCD) microemboli monitoring did not reveal MES. Transesophagial echocardiography (TEE) identified a 5 cm left atrial mass, which was highly suspected to be an atrial myxoma attached to the interatrial septum and prolapsed through the mitral valve. After the TEE results were obtained, another TCD monitoring was performed. Again, there were no MES found in either of the MCAs. Our findings showed the absence of MES on two consecutive TCD examinations, suggesting a spontaneous occurrence, rather than the permanent presence, of embolization, even in the most acute phase of stroke. Thus, the tendency of myxomas to spontaneously produce multiple emboli emphasizes the need for the surgical excision of myxomas.

Context: Stroke caused by basilar artery occlusion is rare, corresponding to 1% of strokes. There is no consensus in the literature on the ideal management of this disease at acute phase. However, mechanical thrombectomy may be a viable treatment option. Case report: 68-year-old female, with no comorbidities, admitted to a secondary hospital 14h after headache, dizziness, vomiting and difficulty walking. She was disoriented, with severe dysarthria and dysphonia, horizontal and vertical ophthalmoparesis and pronation of the right upper limb (NIHSS: 4). Cranial tomography was normal and cranial angiotomography showed a basilar artery thrombosis. Patient was out of the window for intravenous thrombolysis and our hospital did not have another possibility of treatment. Due to high morbidity and mortality, also the possibility of neurological deterioration, medical contact was made with a tertiary hospital with hemodynamic service. During patient transference, she evolved with decreased level of consciousness, aphasia and tetraparesis (NIHSS: 18). Upon arrival at the hospital, a thrombectomy was performed due to an important clinical-radiological mismatch, 19 hours within symptoms onset and 3 hours after neurological worsening. After discharge, patient walked with assistance and physical examination showed a significant improvement in neurological deficits (NIHSS: 6). Conclusions: This case demonstrates the importance of engaging Brazil’s public health system in the management of acute ischemic stroke, especially in challenging cases such as basilar artery occlusion. This patient was the first admitted to our hospital to perform a thrombectomy after effective transference for a tertiary hospital and staff engagement of both hospitals.

A two-year-ten-month-old entire female fancy rat was evaluated for acute-onset neurological signs following a two-month history of lethargy and behavioural changes. Physical examination revealed generalised muscle atrophy. Neurological examination localised the lesion likely to the right thalamus based on suspected left unilateral hemineglect. The patient was euthanased over quality-of-life concerns, and postmortem MRI of the brain was performed, followed by postmortem examination. This showed a lesion in the region of the pituitary which was T1 hyperintense to the brain, T2 isointense to the white matter and hypointense on gradient echo sequences, suggesting subacute haemorrhage. The authors described the clinical presentation and imaging features (MRI) of suspected pituitary apoplexia secondary to a pituitary macroadenoma in an aged female rat. Of particular interest are the findings of unilateral hemineglect and blooming artefact on MRI gradient echo sequences that lead to suspicion of pituitary apoplexia confirmed on postmortem examination.

✓ An unusual case of delayed ischemia following rupture of an aneurysm of the left internal carotid artery is reported. Symptoms occurred twice after clipping the aneurysm and removing most of the subarachnoid blood on the left side the day after subarachnoid hemorrhage (SAH). Initial ischemia due to vasospasm occurred on the left side of the brain on the 8th day after SAH and responded favorably to induced hypervolemia. After complete recovery, a second episode due to vasospasm occurred on the 16th day after SAH on the right side of the brain from which the subarachnoid blood had not been removed. This caused a massive lesion and permanent severe neurological deficits. This case suggests that removal of subarachnoid blood may affect the severity and time course of vasospasm, and emphasizes the necessity of extensive removal of subarachnoid blood for prevention of severe delayed ischemic symptoms.

We describe a case of combined mechanical thrombectomy of the right middle cerebral artery and stent angioplasty of the right internal carotid artery in a severe stroke caused by arterio-arterial embolism due to a traumatic dissection of the internal carotid artery. The patient was admitted with an NIHSS score of 19 and was discharged from hospital with a score of 2. Three months later neurological examination disclosed no pathological findings. The case demonstrates the crucial role of interventional procedures in the treatment of severe stroke where intravenous thrombolysis has little prospect of success.
