These small growths are occasionally found during an autopsy, when not suspected during life. They may be located near the outer surface, or in the deeper tissues. They are yellowish in color, hard and resisting on making a section. The symptoms are negative, and consequently a diagnosis is impossible during life.
Cavernous angiomata occur but rarely, and vary from the size of a pea to that of a walnut. They occur more frequently in men than in women, and in the aged rather than in the young. The tumors are V-shaped, with their base to the surface of the liver beneath the capsule. They are small, reddish bodies, and consist of a series of dilated vessels.
There are no symptoms to suggest their presence; hence the diagnosis can not be made during life, save in rare cases where the tumorous mass becomes large enough to cause obstruction, and an exploratory incision reveals its true nature.
