Magnetic resonance imaging of peripheral soft tissue hemangiomas

Ten patients with soft tissue hemangiomas outside the central nervous system were studied with MR imaging. Eight patients were studied at 1.5 Tesla (T) with T1-weighted and triple echo T2-weighted sequences. Two additional patients were imaged on a 0.5-T system. The MR images were correlated with images from other modalities. Histologic diagnosis was obtained in all cases. It was found that prolonged T2-weighted imaging together with standard spin echo T1 and T2 pulse sequences is a good substitute for contrast-enhanced CT and arteriographic evaluation of soft tissue hemangiomas.

Enchondromatosis and Hemangioma (Maffucci's Syndrome) With Orbital Involvement

Maffucci's syndrome is a rare, congenital disease of unknown cause characterized by the development of multiple enchondromas and soft-tissue hemangiomas. We treated a 34-year-old man with Maffucci's syndrome, bilateral proptosis secondary to multiple intraorbital hemangiomas, corneal exposure secondary to a left facial nerve palsy, and multiple intra-abdominal tumors. The skeletal manifestations were not clinically apparent and were only discovered after a careful radiologic survey. Simultaneous bilateral orbital cavernous hemangiomas should alert the physician to the possibility of Maffucci's syndrome.

Fluid-fluid level: a nonspecific finding in tumors of bone and soft tissue.

Fluid-fluid levels have commonly been reported to occur in aneurysmal bone cysts but have also been seen in telangiectatic osteosarcoma, chondroblastoma, and giant cell tumor of bone. The authors reviewed their experience with nine bone and three soft-tissue tumors that showed fluid-fluid levels on computed tomographic or magnetic resonance images. The bone tumors included fibrous dysplasia, simple bone cyst, recurrent malignant fibrous histiocytoma of bone, two classical osteosarcomas, and four aneurysmal bone cysts. The soft-tissue tumors included soft-tissue hemangioma and two synovial sarcomas. Except for aneurysmal bone cysts, these types of tumors have not been reported to be associated with fluid-fluid levels. Radiologic-pathologic correlation was available in seven patients; in all seven, the fluid-fluid levels indicated prior hemorrhage. The authors conclude that the presence of fluid-fluid levels in bone or soft-tissue tumors cannot be considered diagnostic of any particular tumor.

Ovarian fibrosarcoma associated with Maffucci's syndrome

Maffucci's syndrome, a congenital condition of generalized mesodermal dysplasia, is most often associated with multiple enchondromas and soft tissue hemangiomas or lymphangiomas. This case report describes the development of an unusual ovarian fibrosarcoma and subsequent ovarian adenofibroma in a young woman with the syndrome. The importance of aggressive surveillance in this and similar orthopedic syndromes is stressed.

Oral hemangioma treated with a sclerosing agent: Report of a case

A case of oral soft tissue hemangioma is reported. The treatment of the lesion with a sclerosing agent is described.

MR imaging of soft-tissue hemangiomas: correlation with pathologic findings.

Soft-tissue hemangiomas have been described in MR imaging, but a histopathologic correlation to better understand the MR appearance has not been reported. Five patients with intramuscular soft-tissue hemangiomas were imaged in orthogonal planes on a 1.5-T system with spin-echo (SE) short-TR/TE sequences (600/20) and long-TR/TE sequences (2500/20-80). Complete intact surgical specimens were obtained, and gross and histopathologic findings were compared with MR findings. A striated-septated configuration with a high signal intensity on long-SE sequences (TE greater than 75 msec) correlated with endothelial-lined vascular channels separated by fibrous and/or fatty linear strands. An awareness of the morphologic MR pattern of soft-tissue hemangiomas may aid in recognition of these lesions.

Mucocutaneous and peripheral soft-tissue hemangiomas: MR imaging.

Hemangiomas are common congenital lesions that may have devastating sequelae. The extent and location of a lesion determines the therapeutic approach. We describe 11 patients with mucocutaneous or peripheral soft-tissue hemangiomas to illustrate the ability of magnetic resonance (MR) imaging to define clearly and noninvasively the extent and anatomic relationships of hemangiomas. The major advantage of MR imaging over computed tomography or angiography is the exquisite difference in contrast between hemangiomas and the surrounding structures on T2-weighted MR images, in which hemangiomas have a relatively intense signal. Hemangiomas demonstrated relatively low signal intensity (similar to muscle) on T1-weighted images, which were markedly inferior to T2-weighted images in defining the extent of the lesions. Phleboliths and feeding or draining vessels were rarely visible. The information obtained with MR imaging may be valuable clinically in planning surgical resection or laser therapy of aggressive lesions, in evaluating effectiveness of medical or embolic therapy, and in defining recurrence.

Bilateral Mandibular Arteriovenous Malformation

A short review of the literature and a case report are presented. A lange cavernous hemangioma of the mandible was diagnosed by angiography and subsequently extirpated. Profuse hemorrhage was controlled by packing with oxidized cellulose (Surgicel). After six years a new arteriovenous malformation appeared on the opposite side of the mandible, followed by a soft tissue hemangioma in the left cheek. There was no record of trauma in the anamnesis. Indications for preoperative tomography and angiography are discussed.

Arteriography of peripheral hemangiomas.

Arteriography has proved useful in evaluation of 17 patients with peripheral soft-tissue hemangiomas (15 benign, 2 malignant) by defining their extent, degree of vascularity, and source of vascular supply and allowing differentiation from arteriovenous malformations. In 11 cases (all benign), moderate fine-caliber hypervascularity with some degree of staining was seen. In 6 (4 benign, 2 malignant) there was marked hypervascularity with coarse, irregular vessels. The coarse or fine hypervascularity which characterizes most benign hemangiomas closely resembles that seen in malignant soft-tissue tumors and may preclude correct diagnosis by angiography alone. However, peripheral hemangiomas frequently exhibit distinctive clinical features which when combined with the arteriographic findings enable the radiologist to identify the lesion.
