“…Complete blindness was reported in two papers [ 199 , 212 ]. Visual field defects varied from (mostly common) hemianopia [ 33 , 39 , 55 , 80 , 126 , 135 , 179 , 187 , 197 ] to cranial nerve palsies manifesting as diplopia in the majority of these cases [ 32 , 34 , 35 , 49 , 50 , 58 , 63 , 66 , 68 , 75 , 84 , 85 , 91 , 92 , 114 , 115 , 117 , 127 , 130 , 142 , 147 , 150 , 157 , 163 , 164 , 186 , 191 , 194 , 195 , 207 , 214 ] followed by ptosis [ 34 , 35 , 50 , 59 , 75 , 77 , 79 ,…”

“…The most frequent cranial nerve affected was the oculomotor nerve, but rarely, patients also presented with abducens [ 25 , 44 , 77 , 81 , 84 , 85 , 91 , 98 , 113 , 120 , 121 , 123 , 124 , 128 , 142 , 168 , 174 , 182 , 192 , 207 ] and trochlear [ 25 , 63 , 81 , 84 , 102 , 121 , 123 , 124 , 149 , 168 , 182 , 209 ] nerves palsies. Optic chiasm compression was specified in 18 articles [ 32 , 33 , 46 , 55 , 62 , 63 , 65 , 69 , 80 , 123 , 125 , 169 , 177 , 185 , 186 , 191 , 192 , …”

“…Of note, two unusual triggers are polysubstance abuse [ 191 ] and long restraint in a sitting position [ 221 ]. The patient presented by Sun et al, a 49-year-old male, died in custody due to a gonadotroph PitNET-associated PA following restraint in a sitting position for four days [ 221 ] ( Figure 2 ).…”

Pituitary Apoplexy in Patients with Pituitary Neuroendocrine Tumors (PitNET)

Various complications of pituitary neuroendocrine tumors (PitNET) are reported, and an intratumor hemorrhage or infarct underlying pituitary apoplexy (PA) represents an uncommon, yet potentially life-threatening, feature, and thus early recognition and prompt intervention are important. Our purpose is to overview PA from clinical presentation to management and outcome. This is a narrative review of the English-language, PubMed-based original articles from 2012 to 2022 concerning PA, with the exception of pregnancy- and COVID-19-associated PA, and non-spontaneous PA (prior specific therapy for PitNET). We identified 194 original papers including 1452 patients with PA (926 males, 525 females, and one transgender male; a male-to-female ratio of 1.76; mean age at PA diagnostic of 50.52 years, the youngest being 9, the oldest being 85). Clinical presentation included severe headache in the majority of cases (but some exceptions are registered, as well); neuro-ophthalmic panel with nausea and vomiting, meningism, and cerebral ischemia; respectively, decreased visual acuity to complete blindness in two cases; visual field defects: hemianopia, cranial nerve palsies manifesting as diplopia in the majority, followed by ptosis and ophthalmoplegia (most frequent cranial nerve affected was the oculomotor nerve, and, rarely, abducens and trochlear); proptosis (N = 2 cases). Risk factors are high blood pressure followed by diabetes mellitus as the main elements. Qualitative analysis also pointed out infections, trauma, hematologic conditions (thrombocytopenia, polycythemia), Takotsubo cardiomyopathy, and T3 thyrotoxicosis. Iatrogenic elements may be classified into three main categories: medication, diagnostic tests and techniques, and surgical procedures. The first group is dominated by anticoagulant and antiplatelet drugs; additionally, at a low level of statistical evidence, we mention androgen deprivation therapy for prostate cancer, chemotherapy, thyroxine therapy, oral contraceptives, and phosphodiesterase 5 inhibitors. The second category includes a dexamethasone suppression test, clomiphene use, combined endocrine stimulation tests, and a regadenoson myocardial perfusion scan. The third category involves major surgery, laparoscopic surgery, coronary artery bypass surgery, mitral valvuloplasty, endonasal surgery, and lumbar fusion surgery in a prone position. PA in PitNETs still represents a challenging condition requiring a multidisciplinary team from first presentation to short- and long-term management. Controversies involve the specific panel of risk factors and adequate protocols with concern to neurosurgical decisions and their timing versus conservative approach. The present decade-based analysis, to our knowledge the largest so far on published cases, confirms a lack of unanimous approach and criteria of intervention, a large panel of circumstantial events, and potential triggers with different levels of statistical significance, in addition to a heterogeneous clinical picture (if any, as seen in subacute PA) and a spectrum of evolution that varies from spontaneous remission and control of PitNET-associated hormonal excess to exitus. Awareness is mandatory. A total of 25 cohorts have been published so far with more than 10 PA cases/studies, whereas the largest cohorts enrolled around 100 patients. Further studies are necessary.

Pituitary apoplexy (PA) is a rare, potentially life-threatening condition primarily associated with pituitary adenomas. It presents with sudden, severe symptoms due to inadequate blood supply, bleeding, or tissue death in the pituitary gland. This case report describes a case of PA in a 40-year-old female, and reviews the recent literature surrounding the subject. The patient presented with complete bilateral third nerve palsy and dilated non-reactive pupils. Her initial symptoms included retroorbital headache, fever, and double vision, which rapidly progressed to oculomotor nerve palsy. MRI revealed hemorrhagic PA. High-dose steroids were initiated, leading to the resolution of ptosis. Additionally, surgical intervention was performed. PA typically affects older males with known adenomas, making this case unusual due to the patient's age, gender, and absence of prior adenoma history. Differentiating PA from other intracranial pathologies is crucial, and MRI plays a pivotal role in accurate diagnosis.
