The differential diagnosis for knee pain is extensive. Glomus tumors comprise approximately 1.6% of soft-tissue tumors in the extremities. Classic subungual tumors occur more frequently in women, whereas ectopic locations are more common in men. Unusual locations include the stomach; lungs; trachea; bones; intestines; fallopian tubes; and intraneural, neuromal, and intravenous locations. We present the case of a 50-year-old man with a 12-year history of enlarging right knee mass found to be a glomangioma. This case report discusses the incidence, presentation, imaging characteristics, histology, and management of glomus tumors of the knee.

Stroke is the fifth leading cause of death in the United States and is one of the leading causes of patient disability. Treatments for intracranial intravascular damage as a result of stroke have evolved extensively over recent decades, as management has become increasingly innovative. Various prospective studies and years of data have refined the current guidelines for treatment of acute ischemic stroke (AIS) and also reflect on the novel interventions for stroke management. Nonetheless, AIS remains a difficult and multifactorial etiology of disease to treat. As physicians adapt evidence-based knowledge to their interventional management of patients with AIS, the accompanied use of intravascular devices, such as steerable microcatheters, reduces radiation and procedure time. Considering all of the applications for steerable microcatheters, the use of these devices for AIS interventions may be most necessary.
