Lipoma in the deep lobe of the parotid gland: a case report.
ABSTRACT We report here on a rare case of lipoma in the deep lobe of the parotid gland. MRI revealed that the tumour was situated mainly in the deep lobe and it extended posteriorly and medially into the space between the sternocleidomastoid muscle and the posterior belly of the digastric muscle, with slight extension into the parapharyngeal space. This tumour produced strong signals on T1- and T2-weighted MR images and weak signals on fat suppression images. In addition, MRI clearly showed the margin of the tumour, which enabled us to readily distinguish the tumour from the surrounding adipose tissue. The images suggested a diagnosis of deep lobe parotid lipoma with posteromedial extension to the sternocleidomastoid muscle, which proved true at surgery. We thus believe that MRI is highly useful, perhaps even necessary, in diagnosing tumours of the head and neck.

ABSTRACT: The majority of swellings in the parotid region are sialadenitis, neoplastic lesion or lymph node. Vascular malformation is a rare cause of swelling of the parotid gland. Parotid heamangioma usually presents as a cystic swelling in the preauricular area but may mimic sialadenitis making the diagnosis difficult. We are reporting, to our knowledge, the first case of parotid gland heamangioma with its clinical presentation, radiological and surgical features which extended medially to the temporomandibular joint. The rarity of such condition in head and neck region and misdiagnosis or failing to diagnose make this case more interesting to the maxillofacial surgeon.Tanta Dental Journal. 08/2014;

ABSTRACT: Background Lipomas are common benign soft tissue neoplasms, but they are found less in the head and neck region than other sites. There are few reports of parotid lipoma; especially very rarely in the deep lobe of the parotid gland. Surgical intervention in these tumors is challenging because of the probability of injuring the facial nerve, and thus knowledge of the anatomy and meticulous surgical technique are essential. Case presentation A 63-year-old male presented with a large slow growing, non-tender, asymptomatic, and soft mass, in right parotid region from eleven years ago. Examination of the facial nerve was normal. The computed tomography (CT) scan showed a well-defined giant bilobe lipoma in the superficial and deep lobe of the right parotid gland. Patient underwent tumor excision with facial nerve preservation. We had no complication after surgery. Discussion Giant lipoma of the deep parotid lobe is extremely rare. The computed tomography (CT) scan helps in an accurate and cost-effective preoperative diagnostic method. Surgical management of deep lobe lipoma should be performed by experienced surgeons because of the need for meticulous dissection of the facia nerve.Egyptian Journal of Ear, Nose, Throat and Allied Sciences. 01/2013;

ABSTRACT: This report describes a very rare case of deep lobe parotid lipoma with a brief discussion on the diagnosis and surgical treatment of the lesion. We advocate that CT and MRI are high diagnostic value for parotid lipoma, and that isolated deep parotidectomy without superficial parotidectomy is indicated if lipoma can be confirmed by the preoperative imaging diagnosis.Journal of Oral and Maxillofacial Surgery, Medicine, and Pathology. 05/2012; 24(2):132–135.
