“…The diversity of glomus bodies in the human body means that tumors involving these structures can be found in many different sites. They have been reported in subungual regions, 7,8 and, more rarely, in other areas such as the liver, stomach, lungs, bones, joints, genital organs, central nervous system, and blood vessels. Carotid glomus tumors arise from paraganglion cells and develop in the adventitial layer of the vessel, at the bifurcation of the common carotid artery, in a posteromedial position.…”

Resumo O tumor glômico é uma neoplasia benigna rara originada de células paraganglionares da crista neural que se desenvolve na camada adventícia do vaso. São tumores não encapsulados e altamente vascularizados. Paciente feminina, 64 anos, foi diagnosticada com tumor glômico hipervascularizado com 5 cm posteriormente à bifurcação carotídea esquerda e oclusão de carótida contralateral. Optou-se por realizar embolização através de acesso endovascular seguida de punção percutânea direta, guiada por angiografia, para preenchimento da área remanescente. Após embolização, realizou-se a exérese cirúrgica do tumor com menor sangramento e maior facilidade para encontrar o plano de clivagem das estruturas adjacentes. Em acompanhamento tardio, a paciente apresenta-se sem recidiva tumoral. O tumor foi classificado como pertencente ao grupo Shamblin II, o qual inclui tumores apresentando de 4 a 6 cm com inserção arterial moderada. Através dessa dupla abordagem, foi possível notar uma redução relativa do sangramento intraoperatório e facilitação de identificação do plano de clivagem, colaborando para sua exérese e evitando o pinçamento cirúrgico.

“…Magnetic resonance imaging was positive in all of the cases. It showed solid nodule, hypointense on T1- and hyperintense on T2-weighted image, with homogeneous contrast enhancement [19]. In a study by Trehan et al, MRI findings in 36 of the 46 patients who had pathologically confirmed hand glomus tumor were analysed.…”

Aim. To evaluate soft tissue masses of the hand with magnetic resonance imaging (MRI) and ultrasonography (USG) and to correlate imaging findings with pathological findings. Material and Methods. Thirty-five patients with soft tissue masses of the hand were evaluated with high resolution USG and contrast enhanced MRI of the hand, prospectively over a period of 2.5 years. The radiological diagnosis was then compared with cytology/histopathology. Results. There were a total of 19 (55%) females. The mean age was 27.45 ± 14.7 years. Majority (45%) of cases were heteroechoic. Four cases were predominantly hyperechoic. These were later diagnosed as lipomas. Four cases were anechoic (diagnosed as ganglions). Only four lesions showed hyperintense signal on T1-weighted images. Out of these, 3 were lipomas and one was cavernous haemangioma. Three lesions were hypointense on T2-weighted images. All these lesions were diagnosed as giant cell tumor of the tendon sheath. A correct diagnosis was possible on MRI in 80% of cases (n = 28). Conclusion. MRI provides specific findings for diagnosis of certain soft tissue lesions of the hand. Ultrasonography allows accurate diagnosis of hemangioma/vascular malformations. However, in most conditions, imaging findings are nonspecific and diagnosis rests on pathologic evaluation.
