“…Furthermore, of the few cases with postoperative AHI values reported, all had lipomas smaller than our case. [12,13] Moreover, we could not find a case report with an AHI value as high as our case that decreased significantly after operation --more than 50% decrease in PSG in the second postoperative month -with no complications or residual mass on physical examination or radiological evaluations.…”

“…Case reports identify parapharyngeal and retropharyngeal lipomas as causative lesions. 1,2,4,5,8,10 The patient described by Pellanda, et al, 10 who presented with snoring and OSA, was found to have a 5 ϫ 10-cm mobile mass in the right side of the neck under the sternocleidomastoid muscle. The diagnosis was confirmed using MR imaging, and excision of the mass relieved the OSA.…”

Patients with sleep apnea often are treated by sleep disorder specialists and are studied in a sleep laboratory. The authors present two such patients who ultimately were found to harbor large benign anterior skull base lesions that caused their obstructive sleep apnea (OSA). The first patient had a massive pituitary tumor and had undergone a tracheostomy before the lesion was diagnosed. The second patient had a large frontoethmoidal encephalocele that was diagnosed at the same time as a recommendation for continuous positive airway pressure therapy was being considered. Such therapy in the presence of an encephalocele can be dangerous and even fatal. Although there are case reports of tumors causing OSA, nearly all of these lesions have been large pharyngeal lipomas (some of which were palpable in the neck during physical examination) or growth hormone-secreting pituitary adenomas. The patients reported here were completely unaware of the presence of these large lesions until imaging studies and/or nasal endoscopy were performed. These cases illustrate the need to perform nasopharyngeal endoscopy and also to obtain magnetic resonance images of the head before prescribing therapy for OSA. Neurosurgeons must be aware that large skull base lesions sometimes present only with OSA.

Since lipomas are common soft-tissue neoplasms in other regions of the body, they are found only rarely in the parotid gland and are, therefore, often not considered in the initial differential diagnosis of parotid gland tumours. Even rarer are lipomas arising in the deep lobe of the parotid gland with only 6 cases presented in the literature. Lipomas originating in the parapharyngeal space are also extremely rare. When there is any suspicion, computed tomography and especially magnetic resonance imaging are of high diagnostic value. Fine-needle aspiration cytology seems not to contribute much to an accurate diagnosis. None of these preoperative examinations allows an absolute reliable distinction between a lipoma and a liposarcoma. The preferred treatment is complete surgical excision which will minimize the possibility of a recurrence and will also lead to a definitive diagnosis. We report 3 patients with a lipoma of the deep lobe of the parotid gland, extending into the parapharyngeal space, and discuss differential diagnosis and radiological features of lipomas in this rare location.
