Overview
Subependymálny obrovskobunkový astrocytóm (SEGA) je benígny pomaly rastúci tumor asociovaný so syndrómom tuberóznej sklerózy. Vyskytuje sa takmer výlučne v oblasti foramen Monro. Šírene do parenchýmu hemisféry a znepokojujúce histologické črty ako sú nekrózy, mitózy, mikrovaskulárna proliferácia a pleomorfia sú nezvyčajné, ale vzácne môžu byť prítomné. Prezentujeme prípad SEGA u pacienta, u ktrorého zatiaľ nie sú prítomné ďalšie známky syndrómu tuberóznej sklerózy, s atypickým radiologickým nálezom a mikroskopicky prítomnými nekrózami. Tieto znepokojujúce črty iniciálne viedli k nesprávnej diagnóze glioblastómu. Je diskutovaná diferenciálna diagnóza SEGA.
