𝗧𝗲𝗰𝗵𝗻𝗶𝗾𝘂𝗲:
✅ Axial T1, T2, FLAIR, Coronal T2, Sagittal T1 W Sequences.
✅ Axial 1mm T2 sequence of the Inner Ears.
✅ Diffusion weighted sequences.
𝗖𝗹𝗶𝗻𝗶𝗰𝗮𝗹 𝗶𝗻𝗳𝗼𝗿𝗺𝗮𝘁𝗶𝗼𝗻:
Child 3 years old with bilateral hearing loss.
𝗙𝗜𝗡𝗗𝗜𝗡𝗚𝗦:
🔴 Abnormal appearance of the cochlea with short modiolus and interscalar septum which conditions the cochlea with less than two turn … Type III cochlear hypoplasia.
🔴 Small lateral semicircular canals bilaterally, compared to superior and posterior semicircular canals, with tiny bilateral cystic excrescences of their inner aspects, more prominent on the left side … lateral semicircular canals dysplasia bilaterally.
🔴 The vestibule and other semicircular canals show otherwise normal configuration.
🔴 Average sizes of the vestibular and cochlear aqueducts detected.
🔴 Symmetric normal-sized both internal auditory canals showing normal caliber and intensity of the VII and VIII cranial nerves bilaterally. No abnormalities were visualized in the cerebello-pontine angle cisterns and internal auditory canals.
🔴 Right-sided otomastoiditis manifested by retained secretions within the tympanic cavity and right mastoid air cells and expressing no restricted cholesteatoma could be seen in DWI images.
🔴 Enlarged adenoids with median nasopharyngeal Tornwaldt’s cyst averaging about 12 x 6 mm in axial dimensions.
🔴 Mild diffuse pansinusitis noted.
🔴 Partially empty sella with prominent CSF spaces
𝗢𝘁𝗵𝗲𝗿𝘄𝗶𝘀𝗲:
🟢 Cerebral parenchyma: Normal. No significant signal alteration of the white matter.
🟢 Cerebellum: Normal.
🟢 Brainstem: Normal.
🟢 Extra-axial spaces and basal cisterns: Normal in size and morphology for the patient's age.
🟢 Ventricular system: Normal in size and morphology for the patient's age.
🟢 Midline shift: None.
🟢 Vascular system: No gross vascular anomalies identified.
