“…[1][2][3][4][5][6][7] It is also important for surgeons to know vasculature ahead of time, even without preoperative embolization to improve operative planning. On the basis of our results, 4D-CE-MRA may be equivalent to DSA at the primary diagnosis aimed at identifying the presence or absence of hypervascular tumors.…”

“…Although conventional MR imaging, time-of-flight MRA, and contrast-enhanced MRA have been used in the noninvasive evaluation of tumor vascularity, [2][3][4] their failure to yield hemodynamic information limits their clinical usefulness. Head and neck tumors have been diagnosed by time-resolved contrast-enhanced MRA at 1.5T.…”

Os autores relatam um caso de tumor glômico em ramo da artéria radial que irriga o polegar direito, com história clínica de 4 meses. O doente referia o aparecimento de tumoração de aproximadamente 2,0 centímetros na região interdigital, entre o primeiro e o segundo quirodactilos da mão direita, sobre o músculo flexor curto do polegar, extremamente dolorosa e com dor em progressão. Os exames com aparelho de Doppler bidirecional e o eco-color-Doppler apresentaram, como diagnóstico presuntivo, malformação arteriovenosa, pelo turbilhonamento do fluxo e ausência de estenoses. A tumoração foi retirada por cirurgia aberta e encaminhada para exame histopatológico, com diagnóstico de glomangioma. Este relato descreve uma doença arterial pouco frequente, que causa extremo desconforto ao seu portador, mas que é solucionada pela exerese cirúrgica, sem sequelas.

“…MRI is also useful in detecting lesions that are smaller than 5 mm and to screen for synchronous paragangliomas [30,31]. Contrast enhanced MRI angiography (MRA) does not increase the diagnostic value of MRI but defines the vascularity of the tumor [32].…”

Laryngeal paragangliomas are benign slow growing tumors with symptoms resembling squamous cell carcinoma. Hoarseness or dysphasia are the commonest presenting symptoms and usually it presents as an submucosal mass on laryngoscopy. Ninety percentage of these tumors occur in the supraglottic larynx and the rest in the glottis and the subglottic region. Functional activity is seen in a few (2.9 %), none are associated with paraneoplastic syndromes. A 35-year-old male presented to us with hoarseness of voice since 4 months duration. Contrast arteriography demonstrated that the left superior thyroid artery supplied [80 % of the blood supply to the laryngeal mass. Supraselective embolization was done from the right femorals under local anaesthesia and sedation which was uneventfull. The tumor was excised from lateral pharyngotomy approach with an partial laryngectomy procedure. Microscopy and immune-histochemistry confirmed it to be paraganglioma. Complete surgical resection or partial laryngectomy with meticulous dissection of surrounding tissues and preservation of neurovascular structures gives an excellent prognosis as far as oncological clearance is concerned. Malignant paragangliomas of the larynx are rare and an major meta-analysis is necessary to provide a true biological behaviour of this tumor.
