✓ Cerebral amyloid angiopathy (CAA) has been associated with atypical dementia and a variety of other neurological disorders. Intracerebral hemorrhage is the most striking manifestation of CAA. A 63-year-old patient is described who sustained four intracerebral hemorrhages although he had no predisposing factors other than CAA. The neurological and pathological features of CAA are reviewed, with particular emphasis on the problem of CAA-associated intracerebral hemorrhage. On the basis of the experience with this case, it is recommended that adjacent brain parenchyma be biopsied in all patients undergoing evacuation of intracerebral hematomas of unclear etiology.

✓ Cerebral amyloid angiopathy is recognized as an important cause of spontaneous intracerebral hemorrhage in the elderly normotensive patient. Magnetic resonance (MR) imaging characteristics of this disease entity are rarely mentioned in the literature. The MR imaging findings of an elderly normotensive patient presenting with an acute spontaneous intracerebral hemorrhage secondary to amyloid angiopathy are reported and a brief review of amyloidosis is presented.

✓ The authors operated consecutively on 50 patients with lobar intracerebral hemorrhage during a prospectively designed study period from January, 1986, to March, 1990. They investigated the correlations between the underlying causes and the clinicoradiographic features in 29 patients who showed no angiographic vascular abnormalities, in order to elucidate the operative indication for such cases. Patients with ruptured saccular aneurysm or trauma were not included in this study. There were 15 males and 14 females, ranging in age from 7 to 76 years (mean 52.4 years). Histological diagnoses of the surgical specimens were as follows: vascular malformation in nine cases (arteriovenous malformation (AVM) in six and cavernous malformation in three), microaneurysm in 11, cerebral amyloid angiopathy in six, and brain tumor in two; in the remaining case the cause was not verified histologically. The underlying cause was determined in 96.5% of cases. The mean patient age was lowest in the cavernous malformation group (27.0 years), followed by the AVM (45.8 years), microaneurysm (59.8 years), and cerebral amyloid angiopathy (70.0 years) groups. Four patients with vascular malformation (three AVM's and one cavernous malformation) had previous episodes of bleeding at the same site, whereas none of those with microaneurysms or cerebral amyloid angiopathy had such episodes. On computerized tomography (CT) scans, the round to oval hematoma was related to the presence of an AVM or cavernous malformation in contrast to microaneurysms and cerebral amyloid angiopathy. Upon infusion of contrast material, variable enhancement was seen in five (two AVM's and three cavernous malformations) of the nine vascular malformations while no enhancement was noted in any patient with microaneurysm or cerebral amyloid angiopathy at the acute stage. Subarachnoid extension of the hematoma was associated with cerebral amyloid angiopathy significantly more frequently than with AVM's (p < 0.05) and microaneurysms (p < 0.01). The results suggest that clinicoradiographic pictures in cases with negative angiography are quite different among the three major pathological categories; namely, vascular malformation (AVM and cavernous malformation), microaneurysm, and cerebral amyloid angiopathy. It is suggested that the underlying etiology of a given lobar intracerebral hemorrhage with negative angiography may be predicted by a combination of patient age, history of previous bleeding at the same site, hematoma shape, and subarachnoid extension of the hematoma on CT scans. Based upon these findings, the authors discuss operative indications for such cases.

Introduction: The Boston criteria are used worldwide for in vivo diagnosis of cerebral amyloid angiopathy (CAA). Given substantial advances in CAA research, we aimed to update the Boston criteria and externally validate their diagnostic accuracy across the spectrum of CAA-related presentations and across international sites. Methods: As part of an International CAA Association multicenter study, we identified patients age 50 or older with potential CAA-related clinical presentations (spontaneous intracerebral hemorrhage, cognitive impairment, or transient focal neurological episodes), available brain MRI, and histopathologic assessment for the diagnosis of CAA. We derived Boston criteria v2.0 by selecting MRI features to optimize diagnostic specificity and sensitivity in a pre-specified derivation sample (Boston cases 1994 to 2012, n=159), then externally validated in pre-specified temporal (Boston cases 2012-2018, n=59) and geographical (non-Boston cases 2004-2018; n=123) validation samples and compared their diagnostic accuracy to the currently used modified Boston criteria. Results: Based on exploratory analyses in the derivation sample, we derived provisional criteria for probable CAA requiring presence of at least 2 strictly lobar hemorrhagic lesions (intracerebral hemorrhage, cerebral microbleed, or cortical superficial siderosis focus) or at least 1 strictly lobar hemorrhagic lesion and 1 white matter characteristic (severe degree of visible perivascular spaces in centrum semiovale or white matter hyperintensities multispot pattern). Sensitivity/specificity of the criteria were 74.8/84.6% in the derivation sample, 92.5/89.5% in the temporal validation sample, 80.2/81.5% in the geographic validation sample, and 74.5/95.0% in cases across all samples with autopsy as the diagnostic gold standard. The v2.0 criteria for probable CAA had superior accuracy to the currently modified Boston criteria (p<0.005) in the autopsied cases. Conclusion: The Boston criteria v.2.0 incorporate emerging MRI markers of CAA to enhance sensitivity without compromising their high specificity. Validation of the criteria across independent patient settings firmly supports their adoption into clinical practice and research.

An 86-year-old woman with a history of hypertension, hyperlipidemia, coronary artery disease, and hypothyroidism sought care for subacute, progressive cognitive decline. Five months earlier, she was hospitalized for a small, left temporal, lobar, intracerebral hemorrhage with associated receptive aphasia. Over the next several months, she had a precipitous cognitive decline. She was prescribed memantine by her primary physician because of concern for dementia. One month before seeking care, she was found unconscious in her bathroom, which was believed to be an unwitnessed seizure. Brain magnetic resonance imaging 1 month before the current evaluation showed a prior, small, left temporal hemorrhage and diffuse lobar microhemorrhages on gradient echo imaging, focal leptomeningeal gadolinium enhancement in the left temporal lobe, and multifocal T2 hyperintensity with mass effect, maximal in the left temporal lobe. Electroencephalography showed multifocal, independent epileptiform discharges. She underwent open biopsy of the left temporal lobe, which indicated focal granulomatous inflammation causing vascular destruction, with β‎-amyloid plaques within the cortical and leptomeningeal vessels. The findings were consistent with a diagnosis of amyloid-β‎-related angiitis in the setting of severe cerebral amyloid angiopathy. Because of concern for subclinical seizures and epileptiform discharges on electroencephalography, the patient was started on levetiracetam without substantial change in her mental status. After the biopsy findings demonstrated inflammatory changes consistent with amyloid-β‎-related angiitis, she was started on intravenous methylprednisolone, followed by transition to prednisone. After 6 months of treatment, she had significant clinical and radiographic improvement. Follow-up magnetic resonance imaging at that time showed interval improvement in the T2 hyperintensity and mass effect in the left temporal lobe. She was again independent with her activities of daily living, and memantine was discontinued. Cerebral amyloid angiopathy encompasses a heterogeneous group of diseases characterized by amyloid-β‎ peptide deposition. The most common clinical manifestation of cerebral amyloid angiopathy is lobar intracerebral hemorrhage, which can be multifocal and recurrent but can also result in cerebral ischemia and ischemic leukoencephalopathy.

ObjectiveWe present here a case report of a patient with a family history of intracerebral hemorrhages (ICHs) who presented with multiple large lobar hemorrhages in rapid succession, with cognitive sparing, who was found to have a mutation in the β-amyloid coding sequence of amyloid precursor protein (Leu705Val), termed the Piedmont-type mutation, the second ever reported case of this form of hereditary cerebral amyloid angiopathy (CAA).MethodsTargeted pathologic examination was performed aided by the use of ex vivo MRI.ResultsSevere CAA was observed mainly involving the leptomeningeal vessels and, to a far lesser extent, cortical vessels, with no amyloid plaques or neurofibrillary tangles.ConclusionsThis leptomeningeal pattern of β-amyloid deposition coupled with multiple large hemorrhages demonstrates unique pathophysiologic characteristics of CAA associated with the Piedmont-type mutation, suggesting a potential association between leptomeningeal CAA and larger ICHs.
