Extracranial meningioma presenting as a tumour of the external auditory meatus: a case report

AbstractA rare case of extracranial meningioma presenting as a tumour of the external auditory meatus is reported. Biopsy indicated a diagnosis of meningioma, but the radiological appearance was unusual. For example, computed tomography (CT) scans showed an unenhanced tumour mainly located in the squamous part of the temporal bone which expanded into the external meatus destroying the temporal bone. Magnetic resonance imaging (MRI) revealed that the tumour did not extend into the intradural space.This meningioma, had an obvious tendency for extracranial development. According to the operative findings, the tumour arose from the middle cranial fossa dura and extended through the air cells of the temporal bone into the external meatus, instead of growing intracranially.Secondary extracranial meningiomas of the temporal bone usually have a large intracranial component and cause neurological symptoms. However, this was a very rare case of a small meningioma causing no symptoms except for conductive hearing loss.

Objectives: To describe a unique case of bilateral dehiscence of the malleus and incus heads into the middle fossa making contact with the temporal lobes, along with its clinical implications. Methods: An analysis of a patient case and review of pertinent literature were performed. Results: A patient with a history of right-sided mastoidectomy for cholesteatoma was evaluated for persistent conductive hearing loss. On computed tomography (CT) and magnetic resonance imaging (MRI), the patient had a complete dehiscence of the tegmen tympani on the right, with ossicular heads being located above the floor of the middle cranial fossa. A similar finding to a milder degree was noted on the left. The patient underwent revision tympanoplasty with mastoidectomy with removal of the incus and ossicular chain reconstruction and middle fossa craniotomy for repair of the right epitympanic dehiscence. Conclusions: We present some of the unique imaging and operative findings involved in an unusual presentation of encephalocele in which the bilateral malleus and incus heads rise above the level of the middle fossa floor.

Plurihormonal Pituitary Adenoma

Abstract Objectives To describe the case of a 12-year-old girl with a rare plurihormonal pituitary macroadenoma secreting prolactin (PRL), growth hormone (GH), thyroid-stimulating hormone (TSH), and alpha subunit (α-SU). Case presentation The patient experienced recurrent headaches and progressing loss of vision in one eye. During the examination, abnormalities such as tall stature, coarse facial features, enlarged feet and hands, tachycardia, hand tremor, hyperhidrosis, galactorrhea, and goiter were observed. Head magnetic resonance imaging (MRI) revealed a solid tumor in the anterior and middle cranial fossa, measuring 80 × 50 × 55 mm. A stereotactic biopsy revealed plurihormonal Pit-1 positive pituitary adenoma secreting PRL, GH, and TSH. A pituitary hyperfunction with PRL, GH, TSH, and α-SU excess was diagnosed. The patient was successfully treated pharmacologically with dopamine agonists and somatostatin analogue, and a decrease of tumor volume (30%) was achieved. Conclusions When neurosurgery is not possible, long-term pharmacological treatment of plurihormonal pituitary macroadenoma can be a safe and relatively effective alternative.
