PURPOSE: To determine whether magnetic resonance (MR) tractography of facial nerve (VIIn) is useful to detect perineural invasion in case of parotid cancers. MATERIALS AND METHODS: Thirty patients, aged 18 or over, were enrolled in this prospective study between December 2013 and March 2016 (IRB 5891), with a diagnosis of parotid tumors (15 malignant, 15 benign). They have undergone preoperative MR scans (3.0-T) before surgical management. The parameters of the diffusion-weighted (DW) sequence were b-value of 1000s/mm(2); 32 directions; voxel size: 2mm isotropic; scan time: 9' The post-processing generates whole-neck constrained spherical deconvolution (CSD)-based tractography data and super-resolution track-weighted imaging (TWI) technique...

The intimate anatomical relationship of the facial nerve to the parotid parenchyma has a significant influence on the presenting signs and symptoms, diagnosis and treatment of parotid neoplasms. However, to our knowledge, hyperactivity of this nerve, presenting as facial spasm, has never been described as the presenting sign or symptom of a parotid malignancy. We report a case of carcinoma arising in a recurrent pleomorphic adenoma of the left parotid gland (i.e., carcinoma ex pleomorphic adenoma) that presented with hemifacial spasms...

A 4-month-old infant presented with a painless swelling overlying the left angle of mandible. Ultrasound and magnetic resonance imaging (MRI) revealed a large lesion replacing the entire left parotid gland, with multiple enlarged vessels. Homogeneous enhancement of the lesion was seen on the postcontrast MRI scans. Based on the imaging features, a diagnosis of infantile hemangioendothelioma of the parotid gland was offered. This helped in avoiding any further invasive testing.

A diffuse, chronic, usually bilateral, noninflammatory, nonneoplastic enlargement of major salivary glands is termed as Sialosis or Sialadenosis. It is an extremely uncommon cause for enlargement of the parotid gland. We hereby present a case of a 45-year-old female patient having a swelling at the left preauricular region. The swelling was gradually increasing in size since 6 months. On clinical examination, the swelling was 3 cm × 3 cm, mobile, and nontender. On ultrasonography, it was suggestive of benign parotid lesion or parotitis with cervical lymphadenopathy...

Kimura disease (KD) is a rare chronic inflammatory disorder of unknown etiology representing as solitary or multiple subcutaneous nodules predominantly in the head and neck region. Common sites of involvement are preauricular region, forehead and scalp. The soft tissue localization is often associated with regional lymphadenopathy and enlargement of the major salivary gland. The authors report a patient with KD involving the right parotid and left temporal region managed successfully at our center using a combination of debulking superficial parotidectomy and medicinal therapy...

Sialadenitis is an inflammation or infection of the salivary glands that may affect the parotid, submandibular and small salivary glands. Imaging findings vary among unilateral or bilateral salivary gland enlargement, atrophy, abscess, ductal dilation, cysts, stones and calcification. Imaging can detect abscess in acute bacterial suppurative sialadenitis, ductal changes with cysts in chronic adult and juvenile recurrent parotitis. Imaging is sensitive for detection of salivary stones and stricture in obstructive sialadenitis...

Primary malignant lymphomas of the salivary glands are rare, accounting for 2-5% of salivary gland tumors and 5% of extranodal lymphomas, frequently seen in the parotid gland. There are single case reports mentioned in the literature. Clinical presentation is not characteristic and the disease is often overlooked with delay in diagnosis and treatment. We are reporting a case of bilateral parotid gland lymphoma in a 55-year-old male, presented with bilateral enlarged parotids. Magnetic resonance imaging (MRI) showed bilateral enlarged parotid glands with multiple well-defined intraparotid lesions...

Kikuchi-Fujimoto disease (KFD) is an under-recognized disease most commonly presenting with cervical lymphadenopathy, fever, and cytopenias in young females. Bilateral parotid enlargement is usually caused by infections (e.g., mumps) and autoimmune conditions (e.g., Sjogren syndrome). Parotid enlargement, inguinal lymphadenopathy, and pyrexia of unknown origin are uncommon presenting features of KFD and should be suspected in the appropriate setting.

Facial nerve schwannoma is a rare intracranial tumor. Treatment for this benign tumor has been controversial. Here, we report a case of extracranial facial nerve schwannoma treated successfully by hypo-fractionated CyberKnife (Accuray, Sunnyvale, CA) radiosurgery and discuss the efficacy of this treatment. A 34-year-old female noticed a swelling in her right mastoid process. The lesion enlarged over a seven-month period, and she experienced facial spasm on the right side. She was diagnosed with a facial schwannoma via a magnetic resonance imaging (MRI) scan of the head and neck and was told to wait until the facial nerve palsy subsides...

A 60-year Brazilian woman, presented with an enlarged lymph node in the neck for one year, and a superficial nonulcerated lesion was observed in the scalp. Fine needle aspiration and biopsy of the lymph node revealed amelanocytic metastasis, and immunohistochemistry study showed Melan-A/ Mart-1 antigen (clone A103 and S-100 protein). The entire suspected area of the scalp was further resected and an amelanotic melanoma without angiolymphatic invasion was diagnosed. Ultrasonography and PET-computed tomography showed hypermetabolic cystic area in the right parotid...

Benign lymphoepithelial lesions (BLLs) usually affect the parotid glands, resulting in their asymmetrical enlargement. The condition can be associated with Sjögren's syndrome (SS), which in turn may predispose the affected patient to the development of malignant lymphoma. BLLs arising in the intraoral minor salivary glands are rare; such a lesion should prompt the work-up for SS. In some instances, a BLL of a minor salivary gland could represent the initial stage of a mucosa-associated lymphoid tissue (MALT) lymphoma...

BACKGROUND: The clinical picture of IgG4-related sclerosing disease (IgG4-RSD) may mimic lymphoma, and should be in the differential diagnosis of patients with this clinical picture. CASE SUMMARY: A 32-year-old female had recurrent swelling of both eyelids for more than 15 years. Examination revealed elastic, firm, swollen lacrimal glands about 2-3 cm in diameter that was not painful. Head and orbits magnetic resonance imaging (MRI) showed mass lesions over the bilateral lacrimal glands, submandibular glands, and left foramen of ovale...

Pleomorphic adenoma (PA) is the most common benign salivary gland tumor, accounting for up to 60% of all tumors of the salivary gland and 75-80% of all parotid tumors. It has a slow but progressive growth pattern and if untreated can become greatly enlarged in size. However, giant PA is uncommon. We report a case of giant parotid PA of more than 10 years duration in a 60-year-old male Nigerian. A 60-year-old male patient with 10-year history of painless, massive, and pedunculated swelling in the left side of lower face measuring 25 cm × 23 cm × 17 cm in dimension...

Increased salivary demand can lead to enlarged parotid salivary glands, and increased activity of the masseter muscles can cause masseter hypertrophy. This report describes a most unusual case of simultaneous bilateral hypertrophies of the parotid gland and masseter muscle originating from the very extensive habit of chewing gum. An extensive literature review uncovered many cases of the independent existence of masseteric or parotid hypertrophy, but no example of the simultaneous occurrence of these 2 conditions...

Primary Sjögren's syndrome (pSS) is a relatively common autoimmune systemic rheumatic disease. In addition to sicca syndrome and swollen salivary glands, systemic features manifest in the majority of patients, and are severe in 15%, particularly affecting the joints, skin, lungs, and peripheral nervous system. A recent meta-analysis estimated a pooled relative risk of 13.76 for the development of non-Hodgkin lymphoma, particularly in pSS patients who have parotid enlargement, vasculitis, cryoglobulinemia, and antibodies to Ro and La...

Sarcoidosis is a multisystem granulomatous disorder of unknown cause which may affect any organ or system but primarily involve the lungs and the lymphatic system. Extrapulmonary sarcoidosis represents approximately 30-50% of patients. We report the case of a 51-year-old female who presented with increasing complaints of a cough, weakness, weight loss, and chest pain and who was found to have a suspicious lesion on thorax computed tomography(CT). Fluorodeoxyglucose (FDG) positron emission tomography/CT performed for diagnostic purposes demonstrated increased FDG accumulation at the bilateral enlarged parotid and lacrimal gland and in the reticulonodular infiltration area located in the left lung as well as multiple lymphadenopathies with increased FDG accumulation...
