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.

A case of aneurysmal ("angiomatoid") fibrous histiocytoma (AFH) in a 12-year-old girl is presented with its unusual clinicopathologic features. The lesion had the full microscopic characteristics of AFH described in prior reports, but it also had some features that differed from the original description of the disorder, such as the involvement of subcutis, its occurrence in the scalp, and a documented history of minor trauma. The lesion clinically resembled the gross features of hemangioma. The experience in the present case raises the need for considering AFH as one of major differential diagnosis of nodular cutaneous tumors in children that simulate malignancy such as angiomatoid malignant fibrous histiocytoma and Kaposi's sarcoma.

Littoral cell angioma is a recently described rare vascular tumor of the spleen. The clinical course of this benign tumor is asymptomatic in most patients. Herein, we described three patients with littoral cell angioma detected during physical examination. A brief discussion and review of a handful of cases of splenic littoral cell angioma, which have been previously reported in the English language literature, are performed in this paper.

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.

PURPOSE: To assess the feasibility of using the FLAIR (fluid-attenuated inversion recovery)-HASTE (half-fourier acquisition single-shot turbo spin-echo) sequence for the differential diagnosis of focal hepatic lesions. MATERIALS AND METHODS: During a 12-month period, 80 patients with 127 focal hepatic lesions [hemangiomas (n=60), hepatocellular carcinomas (HCC) (n=27), cysts (n=25), and metastases (n=15)] underwent MR imaging using a 1.5-T scanner. Verification of the diagnosis was based on the findings of pathology (n=11), of angiography and clinical investigation (n=17), or of dynamic contrast-enhanced MR imaging (n=99). MR sequences included T2-weighted HASTE (TE, 134 ms; echo space, 4.4 ms), FLAIR-HASTE (TE, 64 ms; echo space, 4.4 ms; inversion time, 2000 ms; number of slices, 5 -9; acquisition time, 13 -20 s), and dynamic gadolinium-enhanced T1-weighted FLASH (TR, 131 ms; TE, 4 ms). FLAIR-HASTE imaging was of any focal lesions seen on T2-weighted HASTE images was performed in the liver area, and their signal intensity was classified in one of five ways: very high (higher than the spleen), moderately high (similar to the spleen), slightly high (higher than the liver and lower than the spleen), intermediate (similar to the liver), or low (lower than the liver). RESULTS: The signal intensity of the 25 cysts, as determined by FLAIR-HASTE, was low in 21 cases (84%), intermediate in three (12%), and very high in one (4%), which was diagnosed as a complicated cyst in which ultrasound revealed internal septa. At FLAIR-HASTE, all 60 hemangiomas showed either very high (n=50, 83%) or moderately high (n=10, 17%) signal intensity, while that of 42 hepatic malignant tumors was very high in 14 cases (33%), moderately high in 8 (19%), slightly high in 18 (43%), intermediate in one (2.5%), and low in one (2.5%). CONCLUSION: FLAIR-HASTE showed that the signal intensity of the majority of hepatic cysts was low, while that of most hemangiomas and solid liver tumors was high. For the differentiatial diagnosis of cystic and non-cystic liver lesions, FLAIR-HASTE is an easily applicable MR imaging sequence.

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 evaluate the characteristics of MR imaging of hepatic lesions using measurement of apparent diffusion coefficient (ADC) value of hepatic lesions on diffusion weighted imaging.

METHODSMR diffusion weighted images were obtained in patients with 97 hepatic lesions (22 hepatocellular carcinomas, 21 metastatic tumors, 28 hemangiomas, 26 cysts). ADC values were evaluated with different sequences. The ADC ratio of lesion/liver was estimated.

RESULTSAverage ADC values of hepatic lesions were as follows: carcinomas (0.91 +/- 0.07) x 10(-3) mm(2)/s, metastatic tumors (1.13 +/- 0.27) x 10(-3) mm(2)/s, cavernous hemangiomas (1.94 +/- 0.37) x 10(-3) mm(2)/s, cysts (3.26 +/- 0.30) x 10(-3) mm(2)/s. The ADC ratio of lesion/liver was significantly different between primary carcinomas and metastatic tumors (P < 0.05).

CONCLUSIONQuantitative study in hepatic lesions using ADC values and the ADC ratio of lesion/liver, would improve the accuracy in diagnosing hepatic lesions.

We report an extremely rare case of a diffuse hepatic hemangiomatosis without extrahepatic involvement in an adult. The imaging findings of this tumor were similar to those of a hepatic hemangioma and included contrast enhancement with a centripetal filling pattern of the entire hepatic tumor on the delayed phase of a dynamic CT and inhomogeneous diffuse uptake of the entire tumor on blood-pool images obtained five hours later on a 99mTc-labeled red blood cell scan. Despite its rarity, diffuse hepatic hemangiomatosis can be suggested in adult patients with diffusely involved hepatic tumors showing the radiological findings of a hepatic hemangioma.
