    Abstract:
    AIM: The prevalence and risk factors of subclinical haemorrhage on non-functional adenomas (NFA) remain controversial. The primary aim of our study was to assess the incidence of subclinical haemorrhage (SH) and the secondary objectives were to evaluate the risk factors of SH and the impact of SH on pituitary function at diagnosis. PATIENTS AND METHODS: This retrospective transversal analysis included 95 patients between January 2012 and December 2014. The patients included in this series were all adults (>18 years of age), who presented a non-functional adenoma confirmed by an endocrinological evaluation and on dedicated MRI pituitary imaging. Sixty-four patients were eligible for this study. Subclinical haemorrhage was defined by the presence of haemorrhage within pituitary adenoma confirmed by pituitary MRI with no clinical symptoms. A senior neuroradiologist blinded to the diagnosis reviewed all MRI. The population was prospectively divided into two groups based on MRI results (SH group vs. group control) to determine risk factors. RESULTS: SH was diagnosed in 22 patients (34.38%). No risk factors (age, sex, tumor size, chronic hypertension, diabetes mellitus, malignant disease, the use of anticoagulation or antithrombotic medication or Cabergoline treatment) were involved as regards the SH. At the diagnosis, pituitary deficiency was statistically significantly more frequent in the SH group (45.45%) than in the control group (19.04%) (P=0.04). CONCLUSION: The SH within NFA was observed in 34.38% of cases without an association of risk factors.
