BACKGROUND: Schwannomas are benign, slow growing neoplasms of the myelin-producing Schwann cells of peripheral nervous system that most commonly affect sensory nerves. Hypoglossal schwannomas, a tumor of a purely motor nerve, comprise less than 5% of all head and neck schwannomas. Since the first description of a hypoglossal schwannoma in 1933, there have been very few case reports of extracranial origins. The most common location of an extracranial hypoglossal schwannoma is in the parapharyngeal space, and can mimic paragangliomas...

Paragangliomas can be diagnosed accurately using magnetic resonance imaging and dynamic four-dimensional magnetic resonance angiography. Four-dimensional imaging uses the highly vascularised structure of these tumours, which results in a homogenous capillary blush and usually, due to the arteriovenous shunting, in an early draining vein. By these features the tumour can be differentiated from other neoplasms. The authors describe a case of a paraganglioma localised in the middle ear of an elderly patient. Magnetic resonance contraindications led to preoperative diagnostics with high resolution computed tomography of the temporal bone and additionally computed tomography perfusion imaging instead of magnetic resonance imaging with four-dimensional magnetic resonance angiography...

Objective  Treatment for head and neck paragangliomas (HNGPL) can be more harmful than the disease. After diagnosis, an initial period of surveillance is often indicated, and surgery or radiotherapy is reserved for progressive disease. With the aim to optimize this "wait and scan" strategy, we studied growth and possible predictors. Design  A retrospective cohort study was conducted. Setting  This study was conducted at a tertiary referral center for patients with HNGPL. Methods  Tumor volume was estimated for 184 SDHD -related carotid and vagal body paragangliomas using sequential magnetic resonance imaging...

A 58-year-old woman with a past medical history of a carotid body tumor, resected 4 months prior to presentation, was admitted to our hospital for treatment of a cardiac tumor that was identified on post-operative echocardiography and chest computed tomography. The cardiac tumor was surgically removed and identified pathologically as a paraganglioma, similarly to the carotid body tumor. Genetic analysis of both tumors identified a non-synonymous mutation in the succinate dehydrogenase (SDH) gene D, Exon4, c...

A 54-year-old woman was referred to thyroid evaluation because of a lump on the left side of the neck. Ultrasound exam did not show any thyroid abnormality, but highly perfused nodule at the left common carotid artery bifurcation was found. Because of the specific location, somatostatin receptor scintigraphy with Tc EDDA HYNIC-TOC was performed, starting with perfusion images and followed with SPECT/CT imaging at 2 and 4 hours. Well-perfused nodule with intensive accumulation and no other visible pathology in the body raised suspicion of a glomus tumor, consistent with MR exam performed later...

Ectopic thyroid tissue (ETT) lateral to the midline is rare. Its occurrence in the carotid bifurcation is exceptional. We present a 45 years woman who consulted with a slow growing right cervical swelling. Clinical examination Ultrasonography, contrast enhanced CT and cervical MRI concluded to a paraganglioma. Intra-operatively, the tumor didn't have the characteristic aspect of a paraganglioma. Complete excision was performed. Histology concluded to an ectopic micro-vesicular thyroid adenoma.Previous literature was reviewed to summarize clinical and radiologic characteristics of such rare entity...

BACKGROUND: Neuroendocrine tumors of the neck are rare swellings, which constitute about 0.03% of all tumors. Most are sporadically arising paragangliomas. Over 50% arise from the carotid bodies and pose difficulties in diagnosis and surgical management, which may result in disabling complications. OBJECTIVE: To determine the diagnostic, surgical, and postoperative challenges, and how to overcome them, in the management of neuroendocrine tumors of the neck. STUDY DESIGN: Descriptive case series...

IgG4-related disease (IgG4-RD) which is a protein disorder presented as a mass in the right carotid triangle in a 30 year male patient, who underwent battery of tests is described. The radiologist opined the mass as paraganglioma and the spindle shaped character of the mass also suggested neurogenic tumor in differential diagnosis. Reference to vascular surgeon also opined the same, and adviced for incisional biopsy. Histopathology report suggested IgG4-RD and immunochemistry confirmed the final diagnosis...

A woman with hypertension and hyperglycemia was diagnosed a metastatic brain carotid body paraganglioma. Her blood pressure, glucose, and norepinephrine were normal after craniotomy. Although most carotid body tumors are benign, a few show distant metastasis. This is the first reported case of intracerebral metastases from a carotid body tumor.

Despite rapidly growing interest in the therapeutic resection of the carotid body (CB) chemoreceptors, few physiologic studies exist on the consequences of unilateral CB resection. We present a case of an otherwise healthy postmenopausal female who underwent unilateral CB resection for a paraganglioma. Approximately 4 years postoperatively, she underwent analysis of her sympathetic and hemodynamic responses to hypoxia, lower body negative pressure, cold pressor test (CPT), and ischemic hand grip exercise and postexercise ischemia (IHE/PEI)...

We report a rare case of left atrial paraganglioma with a synchronous carotid body paraganglioma in a 30-year-old man with succinate dehydrogenase B gene mutation. The patient initially presented with a neck mass and palpitations. Laboratory test results showed elevated catecholamine levels. A cardiac paraganglioma was identified by computed tomography, meta-iodobenzylguanidine scintigraphy, and magnetic resonance imaging. Surgical resection of both paragangliomas were performed on two separate occasions. Serum and urine catecholamine levels returned to normal range...

Paragangliomas (PGL) develop from the parasympathetic system in the head and neck (HN) and arise primarily in four distinct areas: Carotid body, vagal, middle ear, and larynx. Globally, the diagnosis and morphologic features are the same regardless of anatomic site, however the incidence, frequency of genetic alterations/syndromes and differential diagnosis vary. It is now recognized that nearly 40% of all HN PGLs are hereditary, including a significant subset without a known family history. Now pathologists are central to the evaluation for diagnosis and further management of patients with HNPGLs...

Vagal paragangliomas are rare benign tumors accounting for only 3% of head and neck paragangliomas and arise from vagal ganglions, predominately the nodose ganglion in the carotid sheath. Imaging plays an important role in their diagnosis, differentiation from more common lesions presenting in the carotid space, and management. MRI is the method of choice for investigation when paragangliomas are clinically suspected. The typical salt-and-pepper appearance in T1-weighted images is well known but not specific to paragangliomas...

We present an interesting scenario where a 64 years old male presented with a long standing painless, infra-auricular swelling, which had progressively increased in size. Based on the site, the clinical impression was of a salivary gland lesion and FNAC was performed. The smears were unusually cellular and had necrotic background. The cytological diagnosis was a cystic neoplasm of salivary gland, possibly mucoepidermoid carcinoma. Warthin's tumor was also kept in differential. However, the radiological investigations, which were made available after the FNAC report were conflicting with cytological diagnosis of a malignancy and were characteristic of a carotid body tumor, generally a benign neoplasm...
