| Abstract: | Lymphomatoid granulomatosis is an uncommon lymphoproliferative disorder that frequently has central nervous system manifestations. Lymphomatoid granulomatosis has clinical features similar to both vasculitis and lymphoma. The pathological hallmarks of this disease include necrotic angiecentric and angiodestructive infiltrations of premalignant or malignant lymphoid cells. There are, to the authors' knowledge, only a few magnetic resonance imaging reports and no magnetic resonance angiographic reports of this disorder. Presented here is a case of lymphomatoid granulomatosis producing multiple giant fusiform and saccular aneurysms throughout the major intracerebral arteries, along with patterns of vascular beading typically seen with vasculitis demonstrated by magnetic resonance angiography. |
