CYSTIC LYMPHANGIOMA IN A NEWBORN THORACIC CAVITY: POSTMORTEM CT AND MRI IMAGING DURING PATHOLOGICAL EXAMINATION

Glomus tumor is one of the most common temporal bone tumors. Most of them are benign and locally invasive, some are occasionally able to metastasize and have signs of malignancy. Diagnostic imaging is necessary before treatment. Computer tomography (CT) is traditionally used as a primary method of diagnosis, to recognize changes in the temporal bone. Role of magnetic resonance imaging (MRI) in temporal bone tumor diagnosis is not definitively determined.Purpose. To assess the possibilities of computer and magnetic resonance tomography, to develop an algorithm for the application of diagnostic imaging methods in the diagnosis of glomus tumors of the temporal bone.Material and methods. The article presents the experience of diagnosing 30 patients with glomus tumors.Results. The tympanic form of the glomus tumor was observed in 11 cases (37%), tympano-yugular in 19 cases (63%). CT and MRI data totally coincided in cases of small tumors (type A and B). In the presence of extended forms CT ability of assessing bone invasion, involvement of the internal carotid artery, internal jugular vein, and dural sinuses was lower than the MRI.

Background: MRI imaging offers more sensitivity than CT to cartilage invasion but results in a high rate of false-positive studies which decreases their overall accuracy. The objective is to compare accuracy of CT scan vs MRI in the laryngeal carcinoma. Subjects and Methods: All patients have been diagnosed, with and without contrast, including neck MRI and CT. In order to prevent invalidation, before laryngeal biopsy, MRI and CT scanning have been done such that the images are not altered by peri tumorous inflammation. Results: The MRI classification was right for 20 out of 25 patients (80 percent) and 5 outsized cases: three cT1b lesions were pT1a and two cT1a lesions were squamous cell papilloma’s during pathological examination. CT was accurately identified in 17 out of 25 patients (68%), with 8 understated cases: 3 cT1a lesions by CT were pT1b, 3 cT1a lesions were pT3, and 2 tumours had not been found in the CT scan. Conclusion: Our research showed that MRI in preoperative stage early glottic cancer is more sensitive than CT to accurately select eligible patients for conservatory larynx surgery like super cricoid laryngectomy and cordectomy.

This report describes the diagnosis and treatment of a patient with a rare primary facial nerve paraganglioma as well as a review of the current literature. A 60-year-old male patient presented to our clinic with a 4-month history of left-sided progressive facial paralysis House-Brackmann V. Biopsy taken during facial nerve (FN) decompression confirmed the diagnosis of paraganglioma. The left FN was sacrificed during resection of the mass and a 12-7 jump graft, using the left greater auricular nerve, was performed with acceptable outcomes. The rarity of these tumours does not discount their clinical importance or the necessity to include them in the differential when presented with unilateral FN paralysis. Investigation should begin with CT and MRI imaging to identify and localise the potential mass. Histologic confirmation requires tissue. While surveillance imaging is occasionally an option, often complete surgical resection of the mass and sacrifice of the nerve is necessary.
