Background: Retropharyngeal haematomas are most commonly associated with trauma and anti-coagulant use. This paper describes the first reported case of a spontaneous retropharyngeal haematoma suspected to be due to indomethacin use. Case report: It is proposed that the combination of indomethacin affecting platelet aggregation, alongside the patient coughing, may have led to this retropharyngeal haematoma. Conclusion: The complexities of management are discussed and the current literature reviewed. In the absence of airway compromise or a rapidly enlarging haematoma, patients can be managed conservatively with observation and close discussion with the haematology department. Follow-up imaging is not necessary if the patient's symptoms settle; however, any increase in parathyroid hormone levels must be investigated to exclude a parathyroid adenoma. [ABSTRACT FROM AUTHOR]

Malignant external otitis (MEO) is a severe infection of the external auditory meatus caused by Pseudomonas aeruginosa. Classical features include unrelenting deep otalgia, otorrhoea and granulations in the floor of the ear canal. Treatment is generally protracted antibiotic therapy and monitoring of inflammatory markers; the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Traditionally computed tomography (CT) has been the imaging modality of choice. The authors present a case where magnetic resonance imaging (MRI) has been crucial in the diagnosis and follow up of a patient with MEO.

Two cases of metastatic carcinoma of the temporal bone, that simulated glomus tumours on thorough preoperative evaluation are described. Although rare, metastatic spread to this area is recognized, but presentation in this way is unique.

Spontaneous massive haemorrhage from a parathyroid adenoma is rare. It can cause extensive cervical ecchymosis as well as compression of structures within the neck. We present a case, discuss the diagnostic features and review the literature.

Vestibular nerve dysfunction as the major neuro-otological symptom in one of the osteopetrosis group of bone disorders is unusual. We describe a patient with Engelmann's disease who presented in this manner and who benefited from an eighth nerve decompression procedure. Surgical decompression of the internal auditory meatus to relieve vertigo has to our knowledge not been previously reported in this condition.

Haemangiopericytoma is a rare, soft tissue, tumour with unpredictable biological behaviour. A case of haemangiopericytoma of the parotid salivary gland is reported. The clinical, surgical and histological features are described.
