Hemangioma of temporal bone or intratemporal hemangioma is a rare benign tumor that has no specific symptoms and signs according to computed tomography, magnetic resonance imaging), which makes it difficult to diagnose it early. The percentage of diagnostic errors is quite high. The symptoms of hemangioma of temporal bone depends on its localization. A common localization of hemangioma in the temporal bone is geniculate ganglion and internal auditory canal. According to CT and MRI data, there is no difference between many tumors usually localized in the temporal bone. Angiography complements the preoperative examination, increases the likelihood of a correct diagnosis, and is used to assess the possibility of preoperative embolization. Surgical treatment used in many cases, the purpose of which is the total removal of the tumor. A clinical case of temporal bone hemangioma in a 12-year-old child is presented.
Vascular tumors often localized in the region of head and neck. Intraosseous hemangiomas localized mainly in the vertebrae and in the skull bones, but they are rarely found in the temporal bone. More often, intratemporal hemangiomas are localized in the internal auditory canal or in the area of the geniculate ganglion and Scarpas ganglion, due to the abundant blood supply of these areas. In other areas of the temporal bone, hemangioma is extremely rare. The symptoms depend on the localization and size of the tumor. The main clinical manifestations of the disease: facial nerve palsy, hemifacial spasm, cochleovestibular symptoms. The data of computed tomography (CT) and magnetic resonance imaging (MRI) are non-specific. Angiography is recommended to identify the anatomical features of the vessels like aberrant internal carotid artery, high jugular bulb), the blood supply of the tumor and the possibility of embolization, which significantly reduces the risk of bleeding and damage to important anatomical structures of the temporal bone during surgery. Differential diagnosis is carried out with many diseases of the temporal bone: cholesteatoma, glomus tumor, shwannoma of the VII and VIII cranial nerves, Langerhans cell histiocytosis, rhabdomyosarcoma, etc. Surgical treatment is the method of choice and allows to completely resect the tumor. The article presents a clinical case of intratemporal hemangioma in a patient with a long term symptom of hearing loss.
Tumors in the middle ear rarely have an adenomatous nature. Adenomatous tumors can manifest as neuroendocrine adenoma, endocrine adenoma and middle ear adenoma (or temporal bone adenoma). They may represent the same tumors at different stages of glandular and neuroendocrine differentiation. Middle ear adenoma refers to rare tumors. The tumor can clinically manifest itself with nonspecific symptoms, which makes timely diagnosis difficult. According to computed tomography and magnetic resonance imaging, a soft-tissue tumor with clear boundaries usually is detected in the middle ear, without destructive changes and spreading beyond the middle ear. Usually no difference between adenoma and other middle ear tumors, which makes differential diagnosis difficult. The final diagnosis is usually made according to the histological examination. Surgery is the main method of treatment of middle ear adenoma, the purpose of which is radical resection of tumor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
