Pituitary apoplexy is an uncommon syndrome characterised by sudden onset of headache, meningeal signs, visual disturbances, ophthalmoplegia and confusion. Documented recurrent apoplexy or treated apoplexy is even rarer with only few reports in the literature. Between 1994 and 2001, 18 patients were treated for pituitary apoplexy at Bayindir Medical Centre through transsphenoidal route. In all, topical bromocriptine was applied after tumour resection as described by Ozgen. We hereby present the cases of two patients with recurrent apoplexy 3 and 7 years after the initial surgical treatment for pituitary adenoma with apoplexy. The patients were treated non-surgically with success. Additional treatment in the form of radiosurgery was found necessary for the first patient. Surgical excision of the pituitary tumours with apoplexy reduces the risk of recurrent bleedings but eradication is not a rule. These patients need to be followed closely in the postoperative period for possible recurrence of bleeding.

A 50-year-old woman developed headache and right-sided ophthalmoplegia upon awakening from general anesthesia after liposuction surgery on her abdomen, hips, and thighs. Neuroimaging showed hemorrhage within a previously undiagnosed pituitary adenoma. The confirmatory surgical specimen contained areas of gross infarction and hemorrhage. The anesthesia record revealed intraoperative reduction of systolic blood pressure to 90 mm Hg for 30 minutes from a baseline of 120 mm Hg. This first reported case of pituitary apoplexy during liposuction surgery probably resulted from intraoperative hypotension attributed to a combination of general anesthesia, the use of subcutaneous lidocaine, sequestration of plasma in injured tissues, and blood loss.

The objective of this article is to review clinical outcomes in patients presenting with pituitary apoplexy and compare the results of conservative and surgical management. It took the form of a retrospective review of 30 patients (23M, 7F; age range: 17-86 years) with pituitary apoplexy diagnosed between 1988 and 2004. Presenting features included headache in 27 patients, 'collapse' in three and vomiting in 14. Complete blindness occurred in four patients, monocular blindness in two, decreased visual acuity in 12, visual field loss in 10 and ophthalmoplegia in 15. Only five had no initial visual deficit. CT was the initial mode of imaging in 22 patients: three such scans were initially reported as 'normal' and a further 10 as pituitary tumour only, with no haemorrhage. Ten patients proceeded to early pituitary surgery and 20 were managed conservatively. There was one death 24 days after admission in a patient with multiple co-morbidities. Of the six patients with blindness, three (two conservatively treated) regained partial vision. Of the remaining 19 patients with visual deficits, 10 (two surgically treated) recovered fully and eight (four surgically treated) partly so. At latest follow-up the following pituitary hormone deficiencies were identified: ACTH 19; TSH 20; testosterone 18; ADH (diabetes insipidus) eight. Later recurrence of a pituitary adenoma was observed in seven cases (including six of the 10 surgically treated patients). There was no evidence that those patients managed surgically had a better outcome. Early neurosurgical intervention may not be required in most patients presenting with pituitary apoplexy.

Apoplexy of a pituitary adenoma is a rare and under-diagnosed clinical occurrence. It results from either infarction or haemorrhage into an adenoma of the pituitary gland. Its clinical presentation more often includes rapid development of impaired consciousness, severe headache, visual disturbance and variable association of oculomotor nerve palsy. Meningeal irritation signs are considered very rare and usually not reported as presenting symptoms. A 33-year-old male suffered a pituitary macroadenoma apoplexy, clinically indistinguishable from an infectious meningitis at presentation. Three days after surgery, the patient developed a left ophthalmoplegia due to 3(rd) nerve palsy, which fully resolved within 2 months. A right pterional craniotomy was performed during which complete tumour removal was achieved. In conclusion the authors believe that, despite many reports in the literature, encouraging conservative management in pituitary apoplexy by administering intravenous steroids, surgery should be undertaken in order to avoid eventual visual field defects, relieve pituitary gland compression and prevent a possible recurrent apoplectic episode or tumor re-growth.

Neuroendocrine tumor metastases to the pituitary gland are very rare. There are few case reports of carcinoid tumor metastases to the pituitary, but no cases of pancreatic neuroendocrine pituitary metastases have been reported. In this report we present a 55-year-old female with a sellar mass, ophthalmoplegia and headaches initially thought to represent an invasive null cell pituitary adenoma. However a histological (trans-sphenoidal and liver biopsies) and systemic investigation proved it to be a metastasis of an undiagnosed pancreatic neuroendocrine tumor. Our patient was unique in respect to the location of the metastasis and the uncharacteristically high proliferative index of her tumor. She received conventional therapy consisting of Sandostatin, chemotherapy and radiotherapy as well as labeled somatostatin following an avid uptake on octreotide scanning. Despite a radiological improvement the patient suffered progressive clinical deterioration and died.

The aim of this study is to report the neuro-ophthalmic outcome in patients who underwent transsphenoidal decompression for unilateral or bilateral blindness that was due to pituitary apoplexy. Four patients who were rendered blind (with an absence of light perception) unilaterally or bilaterally as a result of pituitary apoplexy were studied. Neuro-ophthalmic evaluation was performed pre- and post-operatively. Patients underwent CT and MRI pre-operatively and CT post-operatively. All four patients underwent transethmoidal decompression of the pituitary adenoma. One patient underwent a second transcranial procedure to remove the remaining suprasellar component of the tumor. Visual acuity, visual fields and extra-ocular movements were documented during the follow-up period. There were three males and one female. Ages ranged from 40 to 68 years. Three patients had unilateral blindness and one was blind in both eyes. Two of the four patients had associated ophthalmoplegia. All the four patients presented within one week of ictus. One patient underwent surgery within the first week, two patients underwent surgery two and three weeks after ictus and the other patient underwent surgery two months after ictus. The patient who was operated on within the first week recovered from bilateral blindness to a visual acuity of 6/9 and 6/12 with superior quadrantic field defects. The two patients who were operated on two and three weeks after ictus improved to 6/60 in the affected eyes and the patient who was operated on after two months improved to 1/60 in the affected eye. Both the patients with ophthalmoplegia improved completely even though the surgery was delayed by two months for one patient. Although blindness following pituitary apoplexy is rare, visual acuity improves in most patients following transsphenoidal surgery. Early surgery within the first week after ictus leads to excellent visual outcome when compared with surgery that is performed at a later stage. In contrast to visual outcome, ophthalmoplegia improves even if surgical decompression is delayed.

We report a case of pituitary apoplexy occurring in a 74-year-old patient 6 hours after cardiac surgery. The patient presented with confusion, unilateral ptosis and ophthalmoplegia. Neurological examination revealed right oculomotor nerve palsy and decreased level of consciousness. Magnetic resonance imaging showed a hemorrhagic and necrotic pituitary macroadenoma. After prompt endocrinological replacement therapy with hydrocortisone and levothyroxine, the confusion of the patient resolved. Removal of a non-functional macroadenoma with large necrotic areas resulted in full recovery. The physician should be aware of pituitary adenoma infarction after open cardiac surgery and should remember that it can be fatal or cause permanent neurological or endocrine damage without proper treatment. Surgical and endocrine treatment can be life-saving procedures.

We retrospectively analyzed the clinical manifestations, imaging results, and surgical treatment conditions of 72 patients who were diagnosed with hemorrhagic pituitary adenoma between January 2006 and May 2009 at our Department of Neurosurgery. We reached the conclusion that the CT-positive rate was 55.17% and the MRI-positive rate was 94.44%. Sixty-six patients underwent transsphenoidal operations; 6 patients, transfrontal operations; 52, total resections; 10, subtotal resections; and 10, partial resections. All procedures alleviated patients' headaches and stopped vomiting; patients with impaired consciousness gradually became clear-headed after the operations; patients whose preoperative eyesight had been impaired improved to different degrees, and ophthalmoplegia improved. Fifty-six patients were followed, 14 were cured, 32 had alleviated symptoms but 4 did not, and 6 relapsed. Our finding suggests that MRI scanning is superior to CT scanning in the diagnosis of hemorrhagic pituitary adenomas. Surgical decompression should be performed as soon as possible, and transsphenoidal microsurgery is the optimal treatment.

The present study was done to observe the ophthalmic manifestations in patients with intracranial tumor. This was a prospective, purposive, consecutive, observational study conducted in patients with radiologically proven intracranial tumors in the department of Ophthalmology with collaboration of Department of Neuro-surgery of Bangabandhu Sheikh Mujib Medical University from January 2006 to December 2010. All cases had tissue histopathology confirmation post-operatively. The most common type of intracranial tumor was pituitary adenoma (58.04%), followed by craniopharyngioma (20.53%), posterior fossa tumour (12.50%) [medulloblestoma, ependymoma], meningioma (8.04%) [sphenoidalwing meningioma, petroclavel meningioma, oligodendroglioma] and others (0.89%) [nasopharyngial carcinoma, esthesio - astrocytoma]. Common neuro-ophthalmological findings were visual blur (91.07%), visual field defect (71.42%), optic disc changes (50%), pupillary light reaction defect (48.21%) and colour vision defect (46.42%). The study shows, pituitary adenoma is the most common tumor that impairs the visual pathway structures followed by craniopharyngioma, posterior fossa tumour & meningioma. Furthermore, decreased visual acuity, visual field defect, abnormal optic discs, relative afferent pupillary defect and ophthalmoplegia etc. are the common neuro-ophthalmic features that should be carefully examined for early detection of intracranial tumors.

Pituitary adenoma is a common primary brain neoplasm. Pituitary apoplexy (PA) is a rare complication of pituitary adenoma and occurs as the result of sudden tumor growth and following different comorbidities. The authors describe the first case of PA following posterior lumbar fusion surgery performed while the patient was prone. In patients with a preexisting pituitary adenoma, thorough clinical and laboratory investigations should be conducted using an interdisciplinary approach before any planned surgery. In unknown cases of pituitary adenoma, PA should be kept in mind for the differential diagnosis in a case with headache, nausea, vomiting, ophthalmoplegia, visual loss, and electrolyte imbalance concurrent with an ongoing disease state.
