| cavernous angioma | Vascular malformation composed of sinusoidal vessels without a large feeding artery; can be multiple, especially if inherited as an autosomal dominant trait. Synonym: nevus cavernosus. (05 Mar 2000) |

| angioma | <dermatology, oncology> A knot of distended blood vessels atypically and irregularly arranged. most are not tumours but haematomas. (06 Mar 1998) |
|---|---|
| angioma lymphaticum | <oncology, tumour> A localised collection of lymphatic vessels resulting in a nodule or mass. most are congenital. (27 Sep 1997) |
| capillary angioma | <dermatology> Red or purple-coloured vascular skin markings that develop shortly after birth. Most are usually painless and benign and sharply demarcated from surrounding skin, usually located on the head and neck, and grow rapidly. It is caused by proliferation of immature capillary vessels in active stroma, and is usually present at birth or occurs within the first two or three months of life. Some lesions (cavernous haemangioma) will disappear or become harder to see as the child approaches school age. Localised steroid injections have been used successfully to reduce the size of a birthmark but generally they undergo spontaneous regression and involution without scarring and normally require no treatment. (07 Mar 2000) |
| venous angioma | <radiology> Caput medusae, wedge-shaped appearance with its base at the meninges and its apex directed toward the ventricles, prominent medullary vein drains into a markedly enlarged transcortical cerebral vein, angiogram: normal arterial phase without AV shunting (12 Dec 1998) |
| cherry angioma | <oncology, tumour> A benign and common skin growth which is characterised by smooth, bright red growth that may be a millimetre to one quater inch across. Diagnosis is made by appearance of the lesion. More commonly seen on the trunk in individuals over 40 years of age. No treatment is necessary, although cosmetic removal via cryotherapy may be an option. (27 Sep 1997) |
| superficial angioma | <dermatology> Red or purple-coloured vascular skin markings that develop shortly after birth. Most are usually painless and benign and sharply demarcated from surrounding skin, usually located on the head and neck, and grow rapidly. It is caused by proliferation of immature capillary vessels in active stroma, and is usually present at birth or occurs within the first two or three months of life. Some lesions (cavernous haemangioma) will disappear or become harder to see as the child approaches school age. Localised steroid injections have been used successfully to reduce the size of a birthmark but generally they undergo spontaneous regression and involution without scarring and normally require no treatment. (07 Mar 2000) |
| telangiectatic angioma | <tumour> Angioma composed of dilated vessels. Angioma venosum racemosum, tortuous swelling caused by varicosities of superficial veins. Venous angioma, vascular anomaly composed of anomalous veins. (05 Mar 2000) |
| carotid-cavernous fistula | A fistulous communication, of spontaneous or traumatic origin, between the cavernous sinus and the traversing internal carotid artery; a pulsating unilateral exophthalmos and a detectable cranial bruit are common manifestations. (05 Mar 2000) |
| carotid-cavernous sinus fistula | <radiology> Aetiology: laceration of ICA within cavernous sinus; usually secondary to basal skull fractures or penetrating trauma, rupture of an intracavernous ICA aneurysm symptoms: chemosis, conjunctival oedema, bruit findings: focal or diffuse enlargement of cavernous sinus, edematous extraocular muscles, arterial enlargement (pulsating exophthalamus), dilation of superior ophthalmic, facial, and internal jugular veins, occasional sellar erosion/enlargement, enlargement of superior orbital fissure (chronic phase) (12 Dec 1998) |
| cavernous | Relating to a cavern or a cavity; containing many cavities. (05 Mar 2000) |
| cavernous arteries | <anatomy, artery> A number of small branches of the cavernous part of the internal carotid artery. See: ganglionic branch of internal carotid artery, basal tentorial branch of internal carotid artery, marginal tentorial branch of internal carotid artery. Synonym: ramus sinus cavernosi arteriae carotidis arteriae, cavernous arteries. (05 Mar 2000) |
| cavernous body of clitoris | One of the two parallel columns of erectile tissue forming the body of the clitoris; they diverge at the root to form the crura of the clitoris. Synonym: cavernous body of clitoris. (05 Mar 2000) |
| cavernous body of penis | One of two parallel columns of erectile tissue forming the dorsal part of the body of the penis; they are separated posteriorly, forming the crura of the penis. Synonym: cavernous body of penis. (05 Mar 2000) |
| cavernous branch of internal carotid artery | <anatomy, artery> A branch of the cavernous part of the internal carotid artery supplying the walls of the cavernous sinus. (05 Mar 2000) |
| cavernous groove | The groove on the body of the sphenoid bone in which the internal carotid artery lies in its course through the cavernous sinus. Synonym: sulcus caroticus, carotid sulcus, cavernous groove. (05 Mar 2000) |
