“…The tumours are frequently accompanied by cystic areas with clear boundaries, and the arteries and veins move forward or outward. The majority of tumours are neurilemmoma, neurofibroma, and paraganglioma [ 12 , 13 ]. The other types of PPS tumours include lymphoma, haemangioma, lipoma, teratoma, and metastasis, which account for 20% of PPS tumours [ 14 ].…”

Background The purpose of this study was to identify neurogenic tumours and pleomorphic adenomas of the parapharyngeal space based on the texture characteristics of MRI-T2WI. Methods MR findings and pathological reports of 25 patients with benign tumours in the parapharyngeal space were reviewed retrospectively (13 cases with pleomorphic adenomas and 12 cases with neurogenic tumours). Using PyRadiomics, the texture of the region of interest in T2WI sketched by radiologists was analysed. By using independent sample t-tests and Mann‒Whitney U tests, the selected texture features of 36 Gray Level Co-Occurrence Matrix (GLCM) and Gray Level Dependence Matrix (GLDM) were tested. A set of parameters of texture features showed statistically significant differences between the two groups, which were selected, and the diagnostic efficiency was evaluated via the operating characteristic curve of the subjects. Results The differences in the three parameters – small dependence low level emphasis (SDLGLE), low level emphasis (LGLE) and difference variance (DV) of characteristics – between the two groups were statistically significant (P < 0.05). No significant difference was found in the other indices. ROC curves were drawn for the three parameters, with AUCs of 0.833, 0.795, and 0.744, respectively. Conclusions There is a difference in the texture characteristic parameters based on magnetic resonance T2WI images between neurogenic tumours and pleomorphic adenomas in the parapharyngeal space. For the differential diagnosis of these two kinds of tumours, texture analysis of significant importance is an objective and quantitative analytical tool.

Background Neurofibromatosis type 1 is an autosomal dominant disorder with an incidence of 1 in 3000 births. Neurofibromas can occur anywhere in the body. Of all the head and neck tumours parapharyngeal space tumours constitute 0.5%. Neurofibromas can constitute about 9% of all the neurogenic tumours (41%) of the parapharyngeal space. Prevalence of nasal obstruction and obstructive sleep-disordered breathing symptoms due to Plexiform neurofibroma in Neurofibromatosis type 1 is rare amounting to less than 0.5% of cases of parapharyngeal space tumours. Case presentation We present a case report of a 24-year-old female patient of Neurofibromatosis type 1 who presented with obstructive sleep-disordered breathing symptoms due to Plexiform neurofibroma in the parapharyngeal space. She had complaints of progressive nasal obstruction with associated snoring, disturbed sleep, and daytime somnolence without any significantly large external neck swelling. She underwent excision of the right parapharyngeal tumor by combined trans parotid and transcervical approach. After histopathological examination, a diagnosis of Plexiform neurofibroma was made. On 1-year follow-up, she is doing well without any recurrence and her presenting symptoms of obstructive sleep-disordered breathing symptoms had improved. Conclusion The symptoms of obstructive sleep-disordered breathing symptoms need to be kept in mind while evaluating such patients and careful attention needs to be given to the patients who report disturbed sleep. Neurofibromatosis type 1 is a multi-system disease which needs holistic care and approach. Such patients should be offered symptomatic treatment and leading questions on the quality of sleep should be asked. Any treatable cause of disturbed sleep like organic sleep disorder should be treated promptly in such patients.
