Giant vertebro-basilar aneurysm: an unusual cerebello-pontine angle lesion.

Acoustic neuromas (vestibular schwannomas) comprise more than 90 per cent of all cerebello-pontine angle (CPA) lesions. We present a rare case of a giant vertebro-basilar aneurysm presenting as a CPA lesion. The general condition of the patient precluded the completion of the magnetic resonance (MR) sequences. The clinical and limited radiological results (T2 images alone, the features of which were not specific) initially did not lead to a specific diagnosis. To obtain further radiological information a computed tomography (CT) scan with contrast was performed and this revealed the lesion to be an aneurysm. The diagnostic difficulties and the treatment dilemmas of such a lesion are discussed. The importance of fine, axial, post-contrast CT arteriography with three-dimensional reconstruction, MR angiography and digital subtraction angiography are highlighted. The limitations of MR imaging in patients with CPA lesions are discussed.

Extensive maxillary sinus pneumatization.

AIM: To determine the incidence of variations of maxillary sinus pneumatization especially when it is extensive and the associated anomalies. STUDY DESIGN: Two hundred consecutive direct coronal paranasal sinus computed tomography (CT) scans were reviewed retrospectively. Extensive maxillary sinus pneumatization (EMSP) was defined as one in which the largest horizontal and/or vertical dimension of the maxillary sinus equalled or exceeded 90% of the corresponding diameter of the orbit. Further subtype I, II & III were defined depending on whether the pneumatization was extensive in one dimension (horizontal or vertical), two dimensions (horizontal & vertical) and by the presence of sphenomaxillary plate, intermaxillary plate or extension into frontal recess. RESULTS: EMSP was found in 8%, of these 7% were bilateral and 1% was unilateral. (Subtype I, II and III constituting 1%, 3% & 4% respectively). CONCLUSION: EMSP has been defined as a group and a classification proposed. EMSP will result in an atypical clinical picture, has a role in the pathogenesis of frontal sinusitis in some cases and may predispose injury to the orbit during endoscopic sinus surgery (ESS).

Laryngeal cysts: a report of three cases with varying presentations.

Cysts in the larynx are not uncommon and assume importance due to their potential to compromise the airway. A series of three cases of laryngeal cysts is presented. Voice, swallowing, and breathing are the prime functions served by the upper aerodigestive tract, and the three cases presented here illustrate how each of these functions can be interfered with by the development of laryngeal cysts. Despite the presence of overlapping symptoms, there were only subtle symptoms at the onset such as globus sensation (case 1), worsening asthma (case 2), and vocal fatigue (case 3). This case series highlights the importance of understanding these subtle symptoms and the need for a thorough search for these benign but offending laryngeal cysts.

Blindness following medial maxillectomy.

Medial maxillectomy via lateral rhinotomy approach is used in the treatment for tumours affecting the lateral nasal wall. The most frequent complications are crusting, epicanthal scarring and epiphora. The authors report a rare case of blindness secondary to indirect optic neuropathy following medial maxillectomy undertaken to treat a malignant melanoma arising in the lateral nasal wall. It is important to keep in mind, the possibility of this rare complication, while patients are being counselled preoperatively for medial maxillectomy.
