AIM: To assess features of cavernous hemangioma (CH) in the orbit revealed by CT and MRI and summarize prediction of preoperative CT and MRI for the adhesion degree of CH in the orbit. METHODS: A total of 97 patients with pathologically confirmed CH in the orbit were examined with axial and coronal CT scan, and axial, coronal, sagittal, and enhanced fat suppression MRI scan. CT and MRI findings and intraoperative adhesion degrees were retrospectively analyzed. RESULTS: There were 47 patients with slight adhesion, for whom CT and MRI showed round masses with well defined margins in the extraocular muscles; 14 patients with mild adhesion, for whom CT and MRI revealed irregular masses with unclear boundary between CH and the optic nerve in coronal images, and emissary veins in the posterior region of masses in contrast-enhanced images; 36 patients with severe adhesion, for whom CT and MRI exhibited an irregular or ovoid mass filling the orbital apex, or showed distorted and even spiky margins in the posterior region of masses in contrast enhanced images at the presence of a transparent triangle between the mass and the orbital apex. CONCLUSION: Preoperative CT and MRI aid in accurate diagnosis, selection of the surgical approach, and assessment of the adhesion degree and surgical risks for CH.

Recent advances in transplantation techniques have allowed pancreatoduodenectomy, distal gastrectomy,hemicolectomy and small bowel autotransplantation to be the therapy of choice for enormous cavernous hemangioma of the small intestine mesentery. There have been a few case reports about small bowel autotransplantation combined with pancreatoduodenectomy for enormous mesenteric cavernous hemangioma of small intestine. The present surgical methods for enormous cavernous bemangioma of the small intestine mesentery mainly included tumor excision and/or small bowel resection. However, these therapies are not effective for those patients in whom the angiocavemoma has infiltrated the mesenteric artery or pancreas, and these patients often give up therapy. It is recognized that enormous cavernous hemangioma of the small intestine mesentery is a benign lesion, and patients may have an excellent prognosis after complete resection of the lesion.

OBJECTIVE: To investigate the origin of blood supply to cavernous hemangioma of the liver (CHL). METHODS: To observe the relation of cavernous hemangioma of the liver to the hepatic artery and portal vein, we performed serial selective hepatic arteriography in 22 patients. Five patients after ligation of the right hepatic arteries underwent portography and liver staining by in jection of methylene blue into the portal veins and 2 patients had hepatic specimens resected, which were made into a model cast by filling the hepatic veins (yellow) and portal venous branches (blue) with methyl methacrylate after vascular lavage. RESULTS: Serial selective hepatic arteriography showed that hepatic arteries and hemangioma were displayed simultaneously, and that hemangioma was supplied by one to numerous arterial branches. In the portal phase of portography, contrast medium failed to enter the tumor and the intrahepatic branches of the portal vein were pushed aside by the tumor; in the liver parenchymal phase, however, the tumor appeared to be a low-density area. Hepatic arteriography and portography revealed that the fistula between the artery and portal vein may not be existed. The liver stained with methylene blue showed that the normal hepatic parenchyma could be stained with deep blue; in contrast, the tumor was not stained at all. The casting specimens showed that the eroded tumor left a round vacant area because of its total shedding, and no blue stained branches of the portal vein extended into the tumor. CONCLUSION: Blood supply of CHL may originate from the hepatic artery.

Objective To investigate the characteristics of magnetic resonance image (MRI) of spinal cord cavernous hemangioma. Methods Six cases of spinal cord cavernous heman-gioma diagnosed by MRI and confirmed by pathology were reviewed. The characteristics of MRI were analyzed and correlated with pathological characteristics of spinal cord cavernous hemangioma. Results In 4 cases, the tumors were located in thoracic segment of the spinal cord and 2 in cervical cord. All lesions were solitary and the spinal cords were normal or a little thicker. The MRI showed that the images of focus were ball-like popcorn or mulberry with mixed signal,with short T2 signal around the focus. Under microscope, the hemangioma was composed of highly expanded blood sinusoids and its wall was thin and consisted of flat epithelial cells. There were some red blood cells in the cavity of the sinusoid and a little fibrous tissue in the diazoma between blood sinusoids. And also some fresh and old hemorrhages could be seen in the specimen. Conclusion MRI has high sensitivity and specificity in the diagnosis of spinal cavernous hemangioma.

Intrasellar cavernous hemangioma is rare. There are no specific symptoms and the mass effect often mimics pituitary macroadenoma. We present one case of intrasellar cavernous hemangioma that was misdiagnosed. Progressively decreasing vision was the main symptom in this case. The prolactin level was mildly increased but other biochemistry examinations were normal. Magnetic resonance imaging showed an enlarged pituitary fossa and an irregular solid tumor(33 mm × 22 mm × 22 mm) in the sella turcica and parasellar region. Subtotal removal in the case was performed through a transsphenoidal approach. Postoperatively, the patient's visual acuity improved. Through a literature review of 8 intrasellar cavernous hemangiomas, we found most lesions are likely to extend into the suprasellar cistern and cavernous sinus, and total resection is difficult. Transsphenoidal approach surgery should be applied for decompression of the optic nerve and biopsy, and stereotactic radiosurgery is preferable.

Objective: To describe the characteristic appearance of cavernous hemangioma of the liver (CHL) presented in carbon dioxide digital subtraction angiography (CO2-DSA) and to evaluate the significance of CO2-DSA in the diagnosis of CHL. Methods: Both CO2-DSA and iodinated contrast DSA (IC-DSA) were performed in all 16 patients with CHL, and the angiographic manifestations in the same patients were compared. The image quality was rated by three experienced angiographers, and the complications were also assessed. Results: There was good correlation between angiographers on image quality (R = 0. 73). Diagnostic images were obtained with both CO2-DSA and IC-DSA in all CHL patients. No difference was noted between IC-DSA and CO2-DSA in visualizing the proper hepatic arteries and its branches (P>0. 05). CO2-DSA produced better images that clearly described the tumor size, shape and margination than those by IC-DSA (P< 0. 05), but both demonstrated characteristic appearances of early opacification and persistent contrast enhancement of the tumors. The portal vein branches near the tumors were constantly demonstrated by CO2-DSA in 15 cases (15/16) but only in 2 cases (2/16) by IC-DSA. Conclusion: CO2-DSA is sensitive in CHL diagnosis, and in patients with contraindications to IC or with unsatisfactory imaging results by IC-DSA, CO2-DSA is a good alternative. As show in most cases by CO2-DSA, the portal veins might act as the main drainage vein of CHLs.
