- Cervical Haematoma Secondary to Spontaneous Thyroid HaemorrhagePublication . Almeida e Sousa, M; Dutra, E; Matos-Ferreira, GSpontaneous thyroid haemorrhage is rare, but it can be a potentially life-threatening condition in severe cases, due to acute upper airway compromise. We report the case of a 75-year-old patient on chronic anticoagulation therapy for atrial fibrillation, who presented with sudden painful neck bulging and dysphagia. Physical examination revealed a hard mass on the anterior left side of the neck. Preliminary laryngoscopy was normal. The diagnosis was made using ultrasonography and further characterization with computed tomography, showing haemorrhage of a thyroid nodule with capsular disruption and diffusion of the haematoma to the deep cervical spaces, causing important tracheal deviation and hypopharynx compression. The patient developed dyspnoea and ultimately required urgent hemithyroidectomy. This case also highlights the importance of having a high index of clinical suspicion and prompt imaging in patients with atypical presentations of a neck mass.

- Inflammatory Myofibroblastic Tumour of the Common Bile DuctPublication . Almeida e Sousa, M; Carvalho, A; Mega, R; Bilhim, TInflammatory myofibroblastic tumour is a rare entity of indeterminate biological potential with a reduced tendency for recurrence and metastasis. Although it can arise from multiple organs, the bile duct is a very rare site of origin. We report the case of a 75-year-old asymptomatic male with elevated gamma-glutamyl transferase [1575 U/L (12 - 64 U/L)] and alkaline phosphatase [271 U/L (40 - 150 U/L)]. Computed tomography showed a 17 mm hypervascular lesion in the confluence of the right and left hepatic ducts, with bile duct ectasia and right liver lobe atrophy. The patient was initially managed as having a Klatskin tumour and underwent right hepatectomy. Histology showed a spindle cell proliferation with an inflammatory infiltrate of lymphocytes, plasma cells and collagen-rich stroma, consistent with an inflammatory myofibroblastic tumour. He was discharged 30 days after admission, and nine months later remains asymptomatic. His liver function tests have normalized and follow-up tests are unremarkable.
