Abstract/OtherAbstract:
BACKGROUND AND IMPORTANCE:: Following the increased use of endovascular coiling of intracranial aneurysms, a growing number of case reports on complications are being reported. This paper presents a case with a previously undescribed complication to coil treatment: a reactive, non-infectious process after coiling of an unruptured intracranial aneurysm. CLINICAL PRESENTATION:: A 60-year-old hypertensive woman with hypoxic encephalopathy after respiratory arrest following a total thyroidectomy had extensive intentional myoclonus and reduced quality of life as sequelae. An asymptomatic 15 mm ICA bifurcation aneurysm was discovered on MRI six months after the thyroidectomy. After documented growth, the aneurysm was treated endovascularly with bare platinum Gugliemi detachable coils. Three months later, an expansion in the right frontal lobe cranially to the coiled aneurysm was observed. The lesion had grown at 12 months post-coil MRI and, due to its increasing mass effect, was resected through a craniotomy two years after the coiling. Due to lesion regrowth and cyst formation, she underwent a new craniotomy five years later with excision of the now 21 mm large coiled aneurysm, ICA clip reconstruction, and lesionectomy. Five months post-operatively, the process has not recurred. No signs of malignancy or infection were observed during the histological evaluation of the resected tissue. The tissue is described as a reactive, non-infectious process, most likely due to the coils acting as a foreign body. CONCLUSION:: This paper presents a case with a reactive expansive intracerebral process as a complication to endovascular coil treatment of an unruptured intracranial aneurysm.
