Patients with traumatic brain injury (TBI) may develop pituitary dysfunction. Although, there is now increasing awareness of and investigations into such post-traumatic hypopituitarism (PTHP), the exact prevalence and incidence remain uncertain. Here, we aim to identify the incidence of PTHP in a selected population of TBI patients deemed at risk of PTHP at a regional neurosurgical centre in the UK. ⋯ In comparison, in cross-sectional late cohort, 21.3% (10/47) of the patients developed dysfunction in at least one of their pituitary axes at 6 months or more post-TBI, with hypogonadotrophic hypogonadism being the most common. Twenty-two patients from these two cohorts had their growth hormone assessment at 12 months or more post-TBI and 9.1% (2/22) were found to have growth hormone deficiency. Our results suggest that PTHP is a common condition amongst sufferers of TBI, and appropriate measures should be taken to detect and manage it.

Hereditary haemorrhagic telangiectasia (HHT) also known as Osler-Weber-Rendu disease is a rare autosomal dominant condition causing vascular dysplasia. Cerebral abscess formation, secondary to paradoxical septic emboli via HHT-derived pulmonary arteriovenous malformations (pAVMs) in this context is well documented. Herein, we present the first case of subdural empyema with this aetiology.

Dural cavernous haemangiomas are rare, and they do not display a classical ring of haemosiderin on MRI as parenchymal cavernous haemangiomas. Sometimes, they are misinterpreted as meningiomas with a dural tail sign. In this short report, a 37-year-old woman was diagnosed with a convexity cavernous haemangioma, and the tumour was totally resected.
