Cerebral AL lambda-amyloidoma: clinical and pathomorphological characteristics. Review of the literature and of a patient.
BACKGROUND
Amyloid deposits within the brain can be found in a heterogeneous group of diseases. Some of them involve only the central nervous system (AD); others are of systemic origin. Isolated deposits either in the brain, cranial nerves or within the spinal neural structures are extremely rare. So far, we do not know the natural origin, nor the clinical course.


METHODS
We reviewed the overall published cases as far as available and added our own case to learn more about the natural history, clinical and imaging characteristics of this rare brain lesion.


RESULTS
Together with our own case, 27 patients with cerebral amyloidoma were collected in the literature. The lesion always occurred supratentorially, moreover in another two cases also infratentorially. The initial symptoms as well as the results of different neuroimaging features were not specific. There was no predominance for sex and localization. Diagnosis could only be established by histopathological examination after surgical intervention. No recurrence was seen after radical resection; but there was progression in some cases of tumor biopsy.


CONCLUSIONS
Complete surgical removal of cerebral AL amyloidoma seems to be the only way to prevent progression or recurrence of such a brain lesion.
