PURPOSE: To characterize the MR findings for a differential diagnosis and to make a plan for treatment by interventional technique of the vascular masses with/without hypertrophic feeding vessels of the head and neck. SUBJCETS AND METHODS: Seven patients with vascular masses of the head and neck proved by pathology, angiography, clinical findings were included. Vascular masses included 4 venous malformations, a capillary hemangioma, and a hemangiopericytoma, a hemangioma combined with arteriovenous malformation. 7 patients had MR studies with 1.0T and 1.5T using routine TI-, T2- weighted spin echo sequences, and contrast enhancement. 4 MR angiography, 3 inversion recovery, and 6 contrast angiography were studied from 7 patients RESULTS: All vascular masses demonstrated higher than muscle signal intensity on Tl-weighted images, bright signal intensity on T2-weighted images, and prominent enhancement, except AV hemangioma combined with prominent arteriovenous malformation on postcontrast scan. Three hemangiomas demonstrated distinct serpiginous signal voids. Venous malformations demonstrated venous lakes seen as homogenous regions of high signal intensity and phleboliths seen as low signal foci on images. Inversion recovery was the best pulse sequence for evaluation of the extent of lesion. CONCLUSION: MR findings of the vascular masses of the head and neck are useful in delineating the extent of the disease, differentiating venous malformation or cavernous hemangioma from other hemangiomatous lesions including hypertrophic feeding vessels, and making a plan for treatment by interventional technique also.

The hemangioma of bone is a benign lesion that slowly resorbs bones and is defined as a hamartoma. It develops frequently in vertebrae and skull and rare in short tubular bone. A case which occurred in calcaneus is reported here. The patient is 20 year old volley ball player. She had been suffered from intermittent dull pain on left heel and slight swelling for one month. X-ray showed well circumscribed an oat sized radiolucent lesion. Radical curettage and chip bone graft was performed. Pathology confirmed capillary hemangioma by histological examination. At post-operative 3rd month, grafted bone appeared well homogenized with host bone and no pain was complained in daily life.

Infantile hemangiomas are relatively common soft tissue tumors in infants and young children, with a prevalence of about 4.5% in full-term newborns. Subglottic Hemangioma (SGH) is a relatively rare type of hemangioma, and its special location often causes respiratory distress and potentially life-threatening conditions in infants. Therefore, it is necessary for clinicians to make an accurate diagnosis and formulate a detailed treatment plan based on the clinical manifestations, the auxiliary examinations, the medical history and the vital signs evaluation of patients.This review describes the pathophysiological mechanism of infantile hemangioma and provides a detailed discussion on commonly used treatment methods in detail.

OBJECTIVETo investigate the magnetic resonance imaging (MRI) findings of capillary hemangioma in the brain to improve the diagnosis of capillary hemangioma.
METHODSThe MRI findings were analyzed in 6 patients with pathologically confirmed capillary hemangioma in the brain to define the characteristic MRI features of capillary hemangioma.
RESULTSIn the 6 patients, the capillary hemangiomas were located in the pons (n=1), bulbus medullae (n=1), bilateral cerebellar hemisphere (n=1), right temporal lobe (n=1) or left frontal lobe (n=1). Three patients had subacute hemorrhage, 2 had cystic degeneration and 1 had solid tumors, all shoeing heterogeneous MRI signals. Contrast-enhanced MR scans revealed marked heterogeneous enhancement with clear boundaries of the tumor parenchyma, where spots and thin strips without enhancement were seen in 5 cases; vascular network was seen in 1 case. Drainage vessels connected to the lesions were found in 3 cases.
CONCLUSIONMRI has a high diagnostic value for intracranial capillary hemangioma.

A pregnant lady in her third trimester presented with a rapidly growing right-sided nasal mass associated with epistaxis and nasal obstruction for six months. Examination showed a non tender, protruding mass completely occluding her right nostril. Wide surgical excision was done under anaesthesia. Histopathology revealed capillary haemangioma. In a gravid patient with a rapidly growing intranasal lesion, capillary haemangioma should be considered as a differential diagnosis.

OBJECTIVETo investigate the injury effect of high frequency electrocoagulation (HFE) by ultrafine-needle on the cutaneous capillary hemangiomas by histopathologic study of cock comb.
METHODS32 male cocks were randomly divided into 4 groups with 8 animals in each group. 3 experimental groups received HFE with different power (6W, 8W, 10W) on the cock comb. Specimens were taken from cock combs for histologic study immediately after treatment and 7, 14, 21, 28 days later.
RESULTSAfter treatment, the cock combs turned pale and followed with scar formation. The shape of combs changed a lot after high power treatment. Immediately after treatment, the capillary number in the experimental groups decreased markedly under light microscope, compared with that in control group (P < 0.05). After that, the capillary number in experimental group increased. 7 days after treatment, the capillary number in experimental groups was still significantly lower than that in control groups (P < 0.01), but not markedly different between the three experiment groups (P > 0.05). Collagen formation also increased after treatment (P < 0.05), which was higher in experimental groups with high power (P < 0.05, correlation coefficient r > 0.5).
CONCLUSIONSHFE with ultrafine needle can effectively decrease the capillary number in cock comb. The 6W treatment is mini-invasive and will not destroy the comb shape with good cosmetic results. The technique may be used for the treatment of cutaneous capillary hemangioma.
