Chronic myelomonocytic leukemia-related vasculitis mimicking giant cell arteritis
Giant cell arteritis (GCA) is a medium-to-large vessel vasculitis, commonly seen in the elderly, that can produce visual loss.1 Although the diagnosis of GCA is typically made via a temporal artery biopsy (TAB), other vasculitides have been diagnosed by TAB in patients with symptoms and signs initially suggestive of GCA. Chronic myelomonocytic leukemia (CMML) is a myeloid neoplasm characterized by persistent monocytosis, macrocytic or normocytic anemia, and thrombocytopenia.2 We report an unusual case of CMML-associated vasculitis mimicking GCA.Homonymous hemianopsia as the presenting sign of migrainous infarction
Migrainous infarction is a rare complication of migraine headaches that accounts for 0.2%−0.5% of ischemic strokes.1,2 This condition frequently occurs in the posterior cerebral circulation and typically affects a single vascular territory.1,2 The most common symptom preceding an acute migrainous infarction is a visual aura (82.3%) that resolves within minutes to hours.1 Visual field defects like partial or complete homonymous hemianopsia (HH) after a migrainous infarction have been reported, but the prevalence is unknown.
