Generally speaking, venous stones are more common in patients with varicose veins after calcification of venous thrombosis. It is the product of varicose veins developing to a certain period.
Possible symptoms caused by venous stones: paralysis of legs and feet. It's a little swollen
Temporal lobe angiolipoma with multiple venous thrombosis
Clinical data of 1
Patient, female, 14 years old. 2 months' hospitalization due to headache 10 year. Her mother described the patient as suffering from intermittent headache for 65,438+00 years, with severe pain during the attack. In the last two months, my vision has obviously decreased and I have twitched twice. I was unconscious when I convulsed, with swollen eyes, foaming at the mouth and mild mental retardation. Physical examination: Shen Qing, eyes of the same size, reflective, bilateral papillae edema, soft neck, no hemiplegia and hemianopia, no pathological reflection. Auxiliary examination: EEG showed that the temporal lobe was irregular locally, and the δ waves of the affected lines were similar to those of the lateral lines. CT showed high density shadow, uniform echo, clear boundary and irregular enhancement of blood vessels. MRI images are short T 1 and long T 2, and both T 1 weighted and T 2 weighted images are strong signals. Clinical diagnosis: temporal lobe space occupying. We give them selective surgery. During the operation, the tumor was located in the temporal pole, single, with clear boundary and outline, slightly hard and yellowish.
2 Pathological examination
Gross: 3 pieces of non-plastic tissue, with the size of 2cm× 1cm× 1cm, partially wrapped, with yellowish and reddish section, lobulated, mature blood vessels, tubular shape and uniform thickness. Under light microscope: routine HE staining. The tumor tissue is mature fat cells, mixed with a small amount of immature fat cells. The cells are small, round or short spindle-shaped, with large central nucleus, no obvious atypia and seedless mitosis, and vacuoles occupied by lipid droplets in the cytoplasm. Around the tumor tissue, blood vessels are very rich, endothelial cells increase and grow actively, and there is sporadic fibrosis around the blood vessels. Fibroblasts and interstitial cells proliferate between blood vessels, and blood vessels are more than fat. There are many peripheral venous thrombosis, and a large number of calcium salts are deposited in the thrombus, forming venous stones. Pathological diagnosis: angiolipoma complicated with multiple venous stones.
3 discussion
Some people think that the origin of intracranial lipoma is leptomeningeal tissue, while others think that it is caused by congenital dysplasia. Lipoma contains many arteries and veins distributed in connective tissue stroma, and calcification is common. Angiolipoma is a special type of lipoma, which is composed of mature adipose tissue and rich vascular tissue. It usually occurs in midline, brain base, lateral fissure, cerebellar nerve root, lateral ventricle vein, dorsal midbrain and corpus callosum, with corpus callosum as the most common site. This kind of tumor is a small tumor with clear boundaries, which is easy to occur just after puberty, often accompanied by severe pain and characterized by multiple occurrences. Its blood vessels are often confined to the periphery of tumor, and transparent thrombus is common, which constitutes an important diagnostic index. In this case, the formation of venous stones by multiple venules constitutes the particularity of this case, and there are few literature reports.
