The firat caae of hemangioma originating in the skeletal muscle was reported by Linton in 1843. Hemangiama involving the skeletal muscle ia less common and the correct preoperative diagnosis is often not made even tbough they attain considerable size. These tumors have remained asymptamatic and undetected by their hosta. We experienced 5 cases of hemangiama in the skeletal muscle for 2 years since 1979 and the diagnosis were confirmed clinicopathologically.

A case of cavernous angioma of the cerebellar vermis is described. Cevernous angioma is rare vascular malformation of the central nervous system and the cerebellar vermis is very unusual site. Exact preoperative diagnosis of this lesion is difficult because cavernous angioma is angiographically silent and generally accepted to be very rare. The relevant literature is reviewed.

PURPOSE: To assess the usefulness of CISS images in the diagnosis of intraocular lesions, we compared CISSimages with 3mm and 1mm sliced spin-echo T2-weighted images. MATERIALS AND METHODS: In 14 patients with 15intraocular lesions(retinal detachment 10, choroidal melanoma, 2 ; cavernous hemangioma, 1 ; PHPV, 1 ; andretinoblastoma, 1). we used a 1.5T MR unit obtain CISS images and 3mm and 1mm sliced spin-echo T2-weighted images.All lesions were analyzed, and after dividing them into two subgroups(linear lesions, n=11 ; mass lesions, n=4),CISS and spin-echo T2-weighted images were compared for detection rate and conspicuity. RESULTS: With regard tothese two parameters, CISS images were superior to 1mm and 3mm sliced spin-echo T2-weighted images. For theassessment of linear lesions, CISS images (detection rate, 100% ; conspicuity, 2.88) were superior to both 1mm and3mm sliced spin-echo T2-weighted images. For mass lesions CISS images were superior to 3mm sliced spin-echoT2-weighted images, but for conspicuity, there was no significant difference between CISS images (2.75) and 1mmsliced spin-echo T2-weighted images(2.2). CONCLUSION: Due to their higher detection rate and greater conspicuity,CISS images were superior to spin-echo T2-weighted images for the diagnosis of intraocular lesions less than 3mmin diameter ; for the diagnosis of intraocular lesions, they might therefore be a useful adjunct to SE images.

Renal hemangioma is a rare benign tumor which usually causes unexplained painless gross hematuria with clotsin the renal pelvis or ureter. It isgenerally venous origin but may be arterial or mixed venoarterial; it may becapillary but is generally cavernous type which has predilection of submucosal, papillary,and medullary locations.It is very important ot include renal hemangioma in the diffrential diagnosis in cases of unexplained grosshematuria with clots in order to save the renal parenchyme. And preoperative selective renal angiography can offerhelpful diagnostic informations and may be helpful to decide surgical procedure. A case of surgically proven renalhemangioma is reported with a brief review of the literatures.

Cavernous hemangiomas in the submandibular gland (SMG) are rare; therefore, there are few clinicoradiologic pathognomonic findings upon which to base a diagnosis. Thus, a preoperative diagnosis of hemangioma is rare. We reviewed all English language literature on cavernous hemangioma involving SMG published after 1990. The characteristic clinical finding of cavernous hemangiomas involving the SMG is a fluctuant swelling that is unrelated to food intake. On computed tomography, cavernous hemangiomas appear as cystic or enhancing lesions either with or without calcification; however, this is not a pathognomonic finding for diagnosis. Most cavernous hemangiomas are best treated by complete surgical excision; preoperative angiography or embolization is not always required. Cavernous hemangioma should be added to the list of the masses presented a fluctuant swelling that is not associated with postprandial swelling. The treatment of choice is surgical excision without angiography and embolization.

Hemangioma of maxillary sinus is very rare. Preoperative diagnosis of maxillary sinus hemangioma is important since these lesions can frequently cause a large amount of hemorrhage during surgery. A case of hemangioma from maxillary sinus in a 20-yearold woman who presented with epistaxis is reported.

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.

PURPOSE: To analyse the MR imaging characteristics of the soft tissue hemagiomas of the extremity. MATERIALS AND METHODS: We retrospectively reviewed histopathologically proven 18 cases of hemangiomas of the extremity including 15 cavernous hemangiomas, 2 venous hemangiomas and 1 capillary hemangioma. The lesions were frequent in female and low extremity. We analyzed the site, extent, margin, signal intensity, enhancement pattern, the homogeniety of internal architecture, and abnormal vessels near the lesion. RESULTS: The extensive lesions involving multiple muscle and tissue layers were more frequent than localized lesions (12/18). Twelve cases had ill defined margin. In most cases, the lesion was heterogeneous mass composed of nodular and septal components. The nodular component showed intermediate signal intensity in T1WI and hign signal intensity in T2WI. The setal component showed mixed inconstant signal intensity. One case of capillary hemangioma showed relatively homogeneous signal intensity than cavernous hemangioma and the main portion of 2 venous hemangiomas had mutilple tubular signal voids. At least some portion of the lesion was enhanced in all enhanced cases. CONCLUSION: The soft tissue hemangiomas of the extremity showed characteristic MR findings and MRI would be an useful method in the diagnosis of the soft tissue hemangiomas of the extremity.
