Preoperative Diagnosis of Orbital Cavernous Hemangioma

Abstract

99mTc-RBC imaging is safe, easy to perform, and highly accurate in providing adequate clinical and surgical management. As a noninvasive and highly specific method for diagnosing orbital hemangioma, 99mTc-RBC scintigraphy can avoid more invasive imaging or biopsy.

Endonasal endoscopic approach for removal of intraorbital cavernous hemangioma in childhood

“…Nuclear scintigraphy with 99mTc‐RBC single photon emission CT is a noninvasive and highly specific method for diagnosing orbital hemangioma and showed 100% sensitivity and 88.9% specificity for the diagnosis of orbital cavernous hemangioma, with a positive predictive value of 90.9% and a negative predictive value of 100% in the recent literature …”

Incidental Masticator Space Lesion in a Teenager

“…6,7 This imaging modality has also been shown to be highly accurate in the diagnosis of extracranial venous malformations. 8 Because the patient in this case had been completely asymptomatic, no treatment was offered. In symptomatic venous malformations in the head and neck, there are several treatment options that include a multidisciplinary approach based on lesion size and extent, such as laser therapy, embolization, percutaneous sclerotherapy, or surgical resection.…”

The application of technetium-99m-red blood cell scintigraphy in the diagnosis of orbital cavernous hemangioma

“…After a certain period of time, the tumour was filled with 99m Tc-RBC homogeneously. The technique of 99m Tc-RBC scintigraphy may also be used in the noninvasive evaluation of extrahepatic vascular lesions such as vascular tumours of the orbit, which show the characteristic scintigraphic pattern, and can be diagnosed as cavernous hemangioma with a high degree of certainty 8 . Sayit et al 9 reported that, in all patients with OCH whom they studied, the preoperative diagnosis was confirmed by the typical pattern of perfusion blood pool mismatch on the 99m Tc-RBC scintigraphy.…”
