          Abstract

          Background

          Pituitary apoplexy is an acute syndrome of haemorrhage or infarction into the pituitary. The condition is relatively well-described. Less well-described is sub-acute presentation of the same condition.

          Objective

          To compare the clinical presentation and natural history of subacute pituitary haemorrhage/infarction with pituitary apoplexy (acute).

          Method

          Retrospective analysis of a consecutive cohort of 55 patients (33 with pituitary apoplexy, 22 with subacute disease) presenting to University Hospital Plymouth between 1994 and 2019. Comparison of the clinical, endocrinological and radiological features at presentation. Comparison of clinical treatment and subsequent outcomes for the two groups.

          Results

          There were no significant differences in predisposing factors for the two groups. Acute headache was more frequent in the acute group. Chronic headache was common in both groups prior to presentation. Low sodium was more common at presentation in the acute group (11/26 vs 2/19 P = 0.02) otherwise there were no differences in endocrine deficit at presentation. A significant proportion showed an improvement in endocrine function at follow up (acute 8/31, subacute 5/21 P = 1.0). MRI characteristics were variable at presentation and follow up in both groups. Ring enhancement with contrast was more frequent in acute (14/20 vs 3/11 P = 0.03). This appearance resolved at follow up in the majority.

          Conclusions

          Pituitary apoplexy has a characteristic and dramatic presentation. Subacute pituitary haemorrhage/infarction shows similar natural history and outcome. These conditions would appear to represent a spectrum of the same condition.

          UK guidelines for the management of pituitary apoplexy.

          Classical pituitary apoplexy is a medical emergency and rapid replacement with hydrocortisone maybe life saving. It is a clinical syndrome characterized by the sudden onset of headache, vomiting, visual impairment and decreased consciousness caused by haemorrhage and/or infarction of the pituitary gland. It is associated with the sudden onset of headache accompanied or not by neurological symptoms involving the second, third, fourth and sixth cranial nerves. If diagnosed patients should be referred to a multidisciplinary team comprising, amongst others, a neurosurgeon and an endocrinologist. Apart from patients with worsening neurological symptoms in whom surgery is indicated, it is unclear currently for the majority of patients whether conservative or surgical management carries the best outcome. Post apoplexy, there needs to be careful monitoring for recurrence of tumour growth. It is suggested that further trials be carried out into the management of pituitary apoplexy to optimize treatment. © 2010 Blackwell Publishing Ltd.

            Classical pituitary apoplexy: clinical features, management and outcome.

            The term classical pituitary apoplexy describes a clinical syndrome characterized by sudden headache, vomiting, visual impairment and meningismus caused by the rapid enlargement of a pituitary adenoma usually due to haemorrhagic infarction of the tumour. Most published reports looking at the clinical features and management of pituitary apoplexy have not differentiated between patients with clinical and subclinical apoplexy, the latter diagnosed at surgery. Furthermore, little is reported on the clinical outcome, in particular visual and endocrinological, and the role of radiotherapy. The purpose of this study was to observe not only the clinical presentation but also the possible predisposing events, investigations, management, clinical outcome as well as the role of radiotherapy in patients presenting with classical pituitary apoplexy. In a retrospective analysis 1985-96, the medical records of 21 male and 14 female patients (mean age 49.8 years, range 30-74) with classical pituitary apoplexy were reviewed. This represents all patients seen with this condition over the stated period. In all patients, pre- and post- operative measurements were made of FT4, FT3, TSH, PRL, LH, FSH, cortisol (0900 h), GH, oestradiol (females) and testosterone (males). Pituitary imaging was by computerized tomography (CT) scan, magnetic resonance imaging (MRI) or both. Patients were followed for up to 11 years (mean 6.3 years: range 0.5-11). Headache (97%) was the commonest presenting symptom, followed by nausea (80%) and a reduction of visual fields (71%). Hypertension, defined as a systolic > 160 mmHg and/or a diastolic > 90 mmHg, was seen in 26% of patients. MRI correctly identified pituitary haemorrhage in 88% (n = 7), but CT scanning identified haemorrhage in only 21% (n = 6). By immunostaining criteria, null-cell adenomas were the most common tumour type (61%). Transsphenoidal surgery resulted in improvement in visual acuity in 86%. Complete restoration of visual acuity occurred in all patients operated on within 8 days but only in 46% of patients operated on after this time (9-34 days). Long-term steroid or thyroid hormone replacement was necessary in 58% and 45% of patients, respectively. Of the male patients, 43% required testosterone replacement, and long-term desmopressin therapy was required in 6%. Only two patients (6%) with tumour recurrence after transsphenoidal surgery for the initial apoplectic event, subsequently required radiotherapy. In classical pituitary apoplexy, headache is the commonest presenting symptom and hypertension may be an important predisposing factor. MRI is the imaging method of choice. Transsphenoidal surgery is safe and effective. It is indicated if there are associated abnormalities of visual acuity or visual fields because, when performed within 8 days, it resulted in significantly greater improvement in visual acuity and fields than if surgery was performed after this time. Radiotherapy is not indicated immediately as the risk of tumour recurrence is small, but careful follow-up initially with annual imaging is indicated in this group.

              Pituitary apoplexy: a review of clinical presentation, management and outcome in 45 cases.

              To review clinical presentation, management and outcomes following different therapies in patients with pituitary apoplexy. Retrospective analysis of case-records of patients with classical pituitary apoplexy treated in our hospitals between 1983-2004. Forty-five patients (28 men; mean age 49 years, range 16-72 years) were identified. Only 8 (18%) were known to have pituitary adenomas at presentation. Thirty-four (81%) patients had hypopituitarism at presentation. CT and MRI identified pituitary apoplexy in 28% and 91% cases, respectively. Twenty-seven (60%) patients underwent surgical decompression, whilst 18 (40%) were managed conservatively. Median time from presentation to surgery was 6 days (range 1-121 days). Patients with visual field defects were more likely than those without these signs to be managed surgically (p = 0.01). Complete or near-complete resolution occurred in 93% (13/14), 94% (15/16) and 93% (13/14) of the surgically treated patients with reduced visual acuity, visual field deficit and ocular palsy, respectively. All patients with reduced visual acuity (4/4), visual field deficit (4/4) and ocular palsy (8/8) in the conservative group had complete or near-complete recovery. Only 5 (19%) patients in the surgical group and 2 (11%) in the conservative group had normal pituitary function at follow up. One (4%) patient in the surgical group and 4 (22%) in the conservative group had a recurrence of pituitary adenoma. This large series suggests that the patients with classical pituitary apoplexy, who are without neuro-ophthalmic signs or exhibit mild and non-progressive signs, can be managed conservatively in the acute stage.
