Гипертрофическая оливарная дегенерация – редкая форма транссинаптической нейрональной дегенерации, вызванная повреждениями дентаторуброоливарного пути (анатомический треугольник Гийена–Молларе). При магнитно-резонансных исследованиях патология проявляется увеличением размера и гиперинтенсивностью нижнего ядра оливы на Т2-взвешенных изображениях. В статье предоставлены 2 клинических случая гипертрофической оливарной дегенерации, которая была вызвана кавернозными ангиомами с кровоизлиянием в ствол мозга. Знания о данном патологическом изменении в ядрах олив продолговатого мозга, корректная диагностика позволяют избежать ошибочных диагнозов и их последствий.

   Hypertrophic olivary degeneration is a rare form of transsynaptic neuronal degeneration caused by damage to the dentato-rubro-olivary pathway also known as the Guillain–Mollaret triangle. In magnetic resonance diagnostics, this is manifested by increasing the size and hyperintensity of the inferior olivary nucleus in T2-weighted images. The article presents two clinical cases of hypertrophic olivary degeneration, which was caused by cavernous angiomas with hemorrhage in the brainstem. Knowledge about this pathological change in the olivary nuclei of the medulla oblongata and a correct diagnosis help to avoid wrong diagnostic and their consequences.
