Surgical considerations in Labrune syndrome

Purpose: Labrune syndrome (LS) is a rare white matter disease characterized by leukoencephalopathy with intracranial calcification and cysts (LCC). While the intracranial cyst characteristics of LS are for the most part stable, some may require surgical intervention when they develop associated hemorrhage and/or mass effect. To date, no review of the surgical outcomes of cyst decompression in LS has been performed. Case presentation: We report the case of a 16-year-old girl with LS who presented with progressive right hemiparesis from an enlarging hemorrhagic left thalamic cyst. The patient underwent frameless stereotactic cyst aspiration and Ommaya reservoir placement and her hemiparesis subsequently improved. Serial monitoring demonstrated stable decompression of the cyst. Conclusions: The pathophysiology of LS is thought to be diffuse cerebral microangiopathy and it is thought that these microhemorrhages contribute to the formation of intracranial cysts as well as diffuse calcifications. Indications for surgical intervention in LS are not well established and the heterogeneity of lesions compels them to be managed on a case-by-case basis. Based on our literature review, surgery is the standard treatment of choice for patients with progressive symptoms and growing lesions on imaging studies, with outcomes favoring less-invasive stereotactic approaches with contingencies of reservoir placement when cysts recur.
