Adenoid cystic carcinoma (ACC) is an uncommon malignant neoplasm that predominantly arises from major and minor salivary glands, accounting for about 1% of head and neck malignancies. ACCs originating from the pterygopalatine fossa (PPF) are extremely rare. In this case report, we present a 77-year-old male patient who experienced a two-year hemi-facial numbness and mild trismus, with intact nasal mucosa. He underwent Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) which revealed opacification of the left PPF with extension to the left infratemporal fossa and osteolytic areas of the sphenoid bone. Histopathology, following blind biopsies, revealed ACC of the PPF, which was subsequently treated with combined therapy (radiotherapy and chemotherapy). Due to their slow and progressive growth, as well as their tendency for perineural invasion, ACCs should always be considered in the differential diagnosis of painless swelling or nerve dysfunction. To our knowledge, this case is the fifth described in the English literature. [ABSTRACT FROM AUTHOR]

The article describes two cases of glial choristoma of epitympanum or middle ear and the mastoid cavity. A 65-year old male patient with recurrent vertigo and history of chronic otitis media with cholesteatoma treated with mastoidectomy demonstrated mild hearing loss on the right ear. A 68-year old female with a history of fever, vomiting, right-sided otalgia and drowsiness was diagnosed with otitis media and mastoidotis of the right ear and she underwent myringotomy and mastoidectomy.

The article describes the case of a 64-year-old woman with a three-day history of right facial nerve palsy, along with a four-month history of bilateral hearing loss, ear fullness and pain, tinnitus, vertigo, and about 15 kilogram weight loss. Topics discussed include treatment that attenuated the symptoms, findings on medical examination, and differential treatment.

The article describes the case of a 74-year old woman diagnosed with granulomatosis with polyangiitis (GPA) and showed multiple cranial nerve manifestations and nasopharyngeal pseudotumor. The patient demonstrated left facial nerve palsy, hypoesthesia, inflammation and swelling at the left nasopharyngreal area, bilateral sensorineural hearing loss, and mass at the left lateral wall of nasopharynx. She was treated with methylprednisone and cyclosphosphamide. Other symptoms of GPA are indicated.
