Lumbosacral perineural cysts (Tarlov's cysts) are nerve root cysts, which are usually asymptomatic and are detected incidentally on imaging. These cysts are rare with an incidence of 4.6%. We report three cases of Lumbosacral Tarlov's cysts, which presented with cauda equina syndrome and radicular pain syndrome. ⋯ Symptomatic lumbosacral Tarlov's cyst is a rare lesion, and the presentation can be low back pain, cauda equina syndrome or sciatica. Therefore, this entity should be kept in the differential diagnosis of patients presenting with these symptoms. Complete Surgical excision of these symptomatic cysts is the treatment of choice to achieve a cure.

Homonymous hemianopia due to damage to the optic radiations or visual cortex is a possible consequence of tumor resection involving the temporal or occipital lobes. The purpose of this review is to present and analyze a series of studies regarding the use of awake craniotomy (AC) to decrease visual field deficits following neurosurgery. ⋯ AC is a safe and tolerable procedure that can be used effectively to map optic radiations and the visual cortices in order to preserve visual function during resection of tumors infiltrating the temporal and occipital lobes. In the majority of cases, a homonymous hemianopia was prevented and patients were left with a quadrantanopia that did not interfere with daily function.
