A venous hemangioma vein, also known as a nondilated venous malformation, is a benign lesion with irregular medium to large blood vessels, primarily composed of venous vessels, which may be accompanied by scattered smooth muscle fibers and adipose tissue. It is the most common intraorbital tumor of childhood, occurring mostly in early childhood to young adulthood. Pathological examination reveals a lack of peritoneum and an abundance of small veins in the abundant fibrous tissue, which is sometimes diagnosed as fibrovascular tumor. Symptoms and signs】 1. It mostly occurs in children or young adults, and there are more females than males. 2.Initial stage can be intermittent ocular protrusion, chronic progressive ocular protrusion, into positional changes, low head, compression of the jugular vein is protruding aggravation, standing protruding along with the reduction of the protrusion, but still more than the opposite side of the eye bulge, such as accompanied by the hemorrhage within the tumor, ocular protrusion can be suddenly aggravated, decreased visual acuity, increased orbital pressure. The hemorrhage can be repeated. 3. The lesion is mostly located in the upper quadrant of the orbit, and the swelling can be detected in the orbit, with smooth or uneven surface, soft texture and no pressure pain, which can be pressed into the orbit, and the swelling increases when the head is lowered. 4. If the tumor occurs in the anterior orbital region or spreads in the anterior orbital region, purple swelling or red blood vessel mass can be seen under the conjunctiva of the eyelid. Diagnostic methods] 1, mostly occurring in childhood, with repeated bleeding history, orbital rim and soft swelling and conjunctival eyelid head and neck hemangioma diagnosis is not difficult, located in the deep part of the orbit is more difficult. 2.Imaging examination Ultrasound: the border is not clear, the number of echoes within the tumor varies, and multiple tubular patchy echogenic areas can be seen. CT: irregular shape, unclear border or non-rounded occupying lesion, internal density homogeneous or inhomogeneous, CT value is greater than +50Hu, the lesion along the eye than the expansion of the casting-like appearance, there may be vein stones MRI examination: T1WI moderate intensity signal, signal intensity is lower than the fat, and the extraocular muscle similar to the vitreous body than the high T2WI can be presented in the medium or medium-high signal, injected with contrast medium signal of the tumor T2WI can be medium or medium-high signal. The signal of tumor injected with contrast agent is obviously enhanced, and the signal intensity is higher than that of fat; if there is hemorrhage, the T1WI and T2WI will be high signal after 72 hours. Surgical resection is the best choice. 2. Freezing or injection of sclerosing agent is feasible.
