“…Pensak et al [13] reported a 15.2% incidence of sudden unilateral sensorineural hearing loss in CP angle lesions. Merino Galvez et al [14] reported a case of sudden deafness due to cerebellar tumor (desmoplastic medulloblastoma) not strictly located in the CP angle but displacing the fourth ventricle. A similar clinical presentation was noticed in our patient.…”

We describe for the first time an unusual location and clinical presentation of medulloepithelioma, a rare embryonal tumor. A 5-year-old child presented with sudden onset of bilateral hearing loss. On imaging, the lesion appeared to be extra axial and was located in the right cerebello-pontine (CP) angle, extending into middle fossa along the trigeminal ganglion and in front of the brain stem into the opposite CP angle. It did not show any enhancement following contrast administration and had restricted diffusion on diffusion-weighted imaging, simulating an epidermoid. However, in vivo localized proton MR spectroscopy revealed a creatine peak dominated by a large choline resonance, peak of glycine with lactate/lipid and invisible N-acetylaspartate suggestive of a neoplastic lesion and not an epidermoid. Only subtotal resection could be performed and the patient had a stormy post-operative course due to extensive dissemination of the disease.

“…Following the application of chosen criteria, we found only 21 cases of medulloblastoma associated with auditory dysfunction 5,7,11,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] (Table 1). In this study, a gender predominance for male was found (52.3% males, 47.6% females); 38% of the patients were children and 62% of the patients were adults, with a mean age of 23 years (between 2 and 50 years).…”

BACKGROUND. Medulloblastoma is the most common central nervous system embryonal tumor in children. In adults, this tumor is extremely rare, accounting for nearly 1% of primary brain tumors. Raised intracranial pressure signs are common manifestations of posterior fossa tumors, but tinnitus and/or sensorineural hearing loss are very uncommon presenting symptoms. MATERIAL AND METHODS. Starting from a very rare case of a 39-year-old male with left tinnitus and progressive left sensorineural hearing loss as isolated symptoms of a medulloblastoma, we performed a literature survey using the PubMed, ProQuest, Web of Science, Science Direct, Wiley Online search engines for patients with medulloblastoma and tinnitus and/or sensorineural hearing loss. RESULTS. All patients found in the relevant literature with auditory dysfunctions presented sensorineural hearing loss. Other frequent manifestations were: ataxia, facial numbness, vertigo, headache, nystagmus. Two patients were found with tinnitus and sensorineural hearing loss as isolated symptoms of medulloblastoma, as in our case, and in two other cases the sensorineural hearing loss was the unique symptom. With refers to the onset of medulloblastoma, just 3 patients had the first symptoms sensorineural hearing loss and tinnitus. Concerning the tumor location, in patients manifested with isolated tinnitus and sensorineural hearing loss, like our patient, the tumor arised from the internal auditory meatus, extended to the cerebellopontine angle or involved the vestibulocochlear nerve. With regards to treatment, surgery in association with radiotherapy and chemotherapy was elected in most cases (38%). CONCLUSION. It is important to pay attention at patients with isolated auditory dysfunction that may mimic significant posterior fossa tumors, such as a medulloblastoma.

“…Unilateral sudden sensorineural hearing loss can be recognised as an initial symptom of brain tumor, but is most often associated with vestibular schwannomas 2,5,8,[11][12][13]18) . Sudden sensorineural hearing loss caused by medulloblastoma is extremely rare and, to our knowledge, there have been only three previous reports of medulloblastoma manifesting as sudden sensorineural hearing loss 6,7,9) . Sudden hearing loss has been defined as 30 dB or more sensorineural hearing loss over at least three contiguous audiometric frequencies occurring within three days or less 17) .…”

A 19-year-old man presented with a one-year history of dizziness and facial numbness on the right side. His symptoms had begun two years previously with sudden hearing loss on the right side, for which he had consulted an otorhinolaryngologist. The otorhinolaryngologist examined the patient with MR imaging ( Fig. 1) and patient was treated based on a diagnosis of idiopathic sudden hearing loss, but his hearing disturbance did not improve. Details of the treatment were not available. Subsequently, he started suffering from the aforementioned symptoms and consulted our department.On admission, neurological examination revealed decreased facial sensation, absent corneal reflex, slight peripheral-type facial weakness, hearing disturbance on the right side, and horizontal and alternate lateral gaze nystagmus. His motor strength was normal, but limb ataxia was observed on the right side. Pure tone audiometry showed right side sensorineural hearing loss up to 102.5 dB in all frequency bands. MR imaging demonstrated abnormal signals located mainly in the right middle cerebellar peduncle shown as iso to hyperintensity on T1-weighted images and hyperintensity on T2-weighted images. This lesion was faintly enhanced by contrast medium (Fig. 2). A retrospective review of the MR imaging results obtained at the previous INTRODUCTIONSudden sensorineural hearing loss is not a rare condition, and thus may occasionally be encountered by clinicians in daily practice. The incidence of sudden hearing loss has been reported to range from 5 to 20 per 100,000 subjects per year, but the precise incidence is estimated to be higher 14) . The etiology of sudden hearing loss is diverse 4) , and patients with sudden sensorineural hearing loss may show magnetic resonance (MR) imaging abnormalities corresponding to the clinical picture such as labyrinthine hemorrhage, cochlear inflammation, multiple sclerosis, and neoplastic disease 1,16) . Although several previous studies recommended evaluating patients with sudden sensorineural hearing loss by MR imaging to rule out underlying organic disease 1,12,16) , few clinicians seem to be aware that even a small intrinsic lesion has the potential to produce sudden sensorineural hearing loss.We describe a case of medulloblastoma located in the middle cerebellar peduncle that manifested as unilateral sudden sensorineural hearing loss followed by cranial nerves pareses and Department of Neurosurgery, Osaka City University Graduate School of Medicine, Osaka, JapanWe present a rare case of medulloblastoma which presented with unilateral sudden sensorineural hearing loss as an initial symptom. A 19-year-old man was admitted to our hospital with a chief complaint of dizziness and facial numbness on the right side. His illness had begun two years previously with sudden hearing loss on the right side, for which he had been treated as an idiopathic sudden hearing loss. Magnetic resonance imaging demonstrated abnormal signals located mainly in the right middle cerebellar peduncle. We performed partial resection...
