Pituitary apoplexy (PA) typically results from infarction or hemorrhage in a pituitary adenoma, while PA in nonadenomatous pituitary gland is uncommon. Prothrombotic states have never been recognized as precipitating factors for PA. The authors report a case of an elderly female who received prophylactic fractionated heparin therapy due to sepsis, consequent rhabdomyolysis, and overt disseminated intravascular coagulation. On the seventh day of heparin therapy, she reported sudden vision loss, ptosis, diplopia, and severe headache. Severe thrombocytopenia and positive antibodies to the complex of platelet factor 4 and heparin confirmed heparin-induced thrombocytopenia type 2 (HIT). Magnetic resonance imaging disclosed a homogenous pituitary tumor mass with pronounced sphenoid sinus mucosa thickening and two hypointense zones within the tumor mass on contrast-enhanced images consistent with focal ischemic necrosis. The tumor was confirmed to be squamous cell carcinoma with no signs of necrosis. Ischemic necrosis was found within marginal pituitary tissue. This is the first reported case of ischemic PA associated with pituitary metastasis and the first case in which HIT triggered PA. Our case demonstrates that prothrombotic states such as HIT can precipitate ischemic PA. Pituitary metastasis can present with ischemic PA, but radiological features differ from those described in pituitary adenomas. Segregated low-signal intensity zones within the tumor mass on postcontrast images indicate partial infarction of the tumor, which could be a special feature of ischemic PA in pituitary metastasis and has never been described in pituitary adenomas. These are all novel findings and might enlighten the pathogenesis of PA.

Rocky Mountain spotted fever (RMSF) is a disease caused by the Gram-negative coccobacillus Rickettsia ricketsii which has been on the rise since the last decade in the USA. The symptoms are common to the many viral diseases, and the classic triad of fever, rash and headache is not always present when RMSF is diagnosed. It may progress to severe cases such as renal failure, disseminated intravascular coagulation and septicaemia. This report aims to present a fulminant case of RMSF associated with sepsis. It describes a female patient's case that quickly progressed to sepsis and death. The patient showed non-specific symptoms for 5 days before being admitted to a hospital. The fact that she lived in an area highly infested with Amblyomma aureolatum ticks was unknown to the medical staff until the moment she died.

We report a case of Cryptococcus humicolus meningitis complicated by communicating hydrocephalus in an apparently immunocompetent 49-year-old psychiatric patient from a nursing home. He presented with a history of poor oral intake, weight loss, headache, vomiting, blurred vision, frequent falls and unsteady gait for the previous three months. He had a history of chronic cough, productive of whitish sputum for the previous month but no hemoptysis. Cerebrospinal fluid culture was positive for Cryptococcus humicolus. He was treated with intravenous amphotericin B and oral fluconazole and had clinical and microbiological improvement after three weeks of treatment. Unfortunately, the patient acquired nosocomial methicillin-resistant Staphylococcus aureus infection and died due to overwhelming sepsis.

A systematic study of thrombophilia markers in a large series of patients with cerebral venous thrombosis (CVT) from India is scarce. The present study was undertaken to know the prevalence of common hereditary thrombophilia in a large series of CVT patients from India. Six hundred and twelve (354 men, 219 women and 39 children) consecutive patients with CVT admitted to various hospitals in Mumbai between 2001 and 2010 were investigated for the common thrombophilia markers, that is, protein C (PC), protein S, antithrombin (AT), and factor V Leiden (FVL) mutation. The main presenting clinical manifestations included papilledema (62%), headache (62%), hemiparesis (48%), seizures (31%), and cranial nerve palsy (7%). All the patients were managed with heparin followed by warfarin during the succeeding 6 months. Superior sagittal sinus thrombosis was the commonest site (74%) followed by cortical venous thrombosis (15%). Associated clinical pathologies were dehydration, sepsis, pregnancy and puerperium, malaria, and tuberculosis; but in the majority of patients, there was no obvious cause. Eighteen percent of the patients had any of the thrombophilia markers studied; PC deficiency was the commonest thrombophilia marker followed by deficiency of protein S, FVL mutation and AT deficiency. The men below 45 years with PC deficiency (P=0.03) and women with protein S deficiency were significantly higher (P=0.04). In conclusion, CVT is not an uncommon cause of neurological deficit as was presented in earlier reports. Pregnancy and puerperium-related CVT was much less common. Thrombophilia markers accounted for approximately one-fifth of the patients. Death due to CVT has shown remarkable reduction (13%) because of early diagnosis and appropriate anticoagulation.

Aggressive dual antiplatelet therapy is associated not only with more bleeding, impaired wound healing, and potentially more solid cancer rates but it also causes higher infection risks including sepsis, and systemic inflammatory response syndrome (SIRS). This may be especially true considering the alarming off-label use of prasugrel. A 65-year-old white male patient with a history of myocardial infarction treated with percutaneous coronary intervention and implantation of 2 bare metal stents, was treated with off-label clopidogrel for 4 years, including a double daily dose (150 mg) for the initial 13 months. Still on clopidogrel, the patient was hospitalized with suspected pneumonia. A diagnostic cardiac catheterization revealed a 60%-70% blockage of the mid left anterior descending, but there was no need for coronary intervention. At discharge, clopidogrel 75 mg/d was switched over to off-label prasugrel 10 mg/d on top of aspirin (81 mg/d). On day 3 after prasugrel was given, a football-sized bruise appeared on the patient's lower right abdomen, but computed tomography results were unremarkable. On day 6 after administration of prasugrel, the patient became dizzy, disoriented, confused, experienced difficulty breathing, severe headache, weakness, intensive petechial rash covering the entire body, and breathing difficulty requiring ventilation. Within 24 hours, the patient was unable to correctly identify his age; his eyes were pale in color to almost colorless and when hearing a sound he would turn his entire head toward the sound and he appeared to be blind. His lungs, liver, and kidneys began to show signs of failure over the next 5-9 days. Sixteen days after the administration of the first prasugrel dose, the patient died of sepsis complicated with SIRS. Aggressive off-label use of clopidogrel (double dose for 13 months, and >4 years overall duration), followed by off-label switchover to the highest daily dose (10 mg) prasugrel may trigger sepsis and fatal SIRS. The mechanism responsible for such harmful association is probably indirect, and involves the weakening of platelet-neutrophil-endothelial crosstalk necessary to combat infections, and/or keep inflammation from spreading.

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological syndrome in which patients present with an acute or subacute clinical presentation of seizures, visual disturbances, headache, and altered mental status. The pathophysiology of PRES may be explained by endothelial dysfunction that leads to transudation of fluids and protein, resulting in vasogenic cerebral edema. PRES is typically associated with many conditions such as hypertension, uremia, immunosuppressive drugs, and sepsis. This is a case report of a 39-year-old woman with untreated HIV infection and end-stage renal disease (ESRD) who developed PRES with a normal blood pressure and no other known causes of PRES. Untreated HIV is associated with known endothelial dysfunction and we believe that this, in combination with her untreated end-stage renal disease, contributed to her unique presentation of PRES. Although uncommon in HIV-infected patients and challenging to diagnose, prompt recognition of PRES is critical to provide appropriate care and ensure reversibility of the vasogenic edema seen in PRES.

We reviewed neurologic complications after renal transplantation in children over a 20-year period. Neurologic complications were classified as early (within 3 months) and delayed (beyond 3 months). Of 115 children, 10 (8.7%) had complications. Early complications were found in 4.35% of patients: seizures in 4 (posterior reversible leukoencephalopathy syndrome due to immunosuppressant toxicity, sepsis/presumed meningitis, and indeterminate) and headaches in 1. One patient with seizures received levetiracetam for 6 months and 1 with headaches received amitriptyline prophylaxis. Late complications were noted in 4.35% of patients: seizures in 3 (posterior reversible leukoencephalopathy syndrome due to hypertension, hypertensive encephalopathy), headaches in 2, and tremors in 1. Two patients with seizures were treated with anti-epilepsy medications; 1 with migraine received cyproheptadine prophylaxis. Neurologic complications develop in children after renal transplantation. Seizures due to posterior reversible leukoencephalopathy syndrome were the commonest complication. Early detection and appropriate management of these complications is important.

A 40-year-old man was admitted to our hospital because of the acute onset of fever and headache, which were attributed to bacterial meningitis. Antibiotic treatment was initiated and his condition gradually improved. On day 5 after admission, immediately after masturbation, he developed abrupt onset of severe chest pain and cold sweat and the ECG suggested acute anterior myocardial infarction. Immediate coronary angiography revealed spontaneous dissection of the left anterior descending artery. After conservative management, his cardiac function improved. Acute coronary syndrome may be rarely caused by spontaneous coronary artery dissection. Sepsis was considered as a probable trigger for spontaneous coronary artery dissection, possibly through vascular damage from increased nitric oxide and sympathetic nervous over-activation.

Brain abscesses are a rare but potentially lethal neurological lesions, generally occurring after septic episodes in immunodeficient patients or complicating neurosurgical procedures. Even though they are known complications of surgically treated intracerebral haemorrhages (ICH), the presence of a brain abscess at the site of an untreated ICH is a rare event. Such cases may result from haematogenous spread from distant foci or contiguous sites and are often preceded by episodes of sepsis and local infection. Immunodeficiency, AIDS, age, diabetes mellitus and vitamin-K deficiency are predisposing factors. Abscess formation should be considered in case of clinical deterioration, headache, and any neurological deficit after febrile episodes. Early diagnosis with neuroradiological imaging, infection blood markers and microbiological identification of the causative pathogen is crucial for treatment with surgical drainage or excision and specific antibiotic therapy, which guarantee good outcome and long-term survival. In fact, while prompt diagnosis and treatment guarantee good outcome and long-term survival, morbidity and mortality are very high in case of misdiagnosis. We report a case of a 49-year old man presenting with a brain abscess 13 weeks after a spontaneous ICH, without previous episodes of sepsis and with a suspected septic arthritis 2 weeks after abscess drainage.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuroradiological syndrome characterized by various symptoms of neurological disease. It has commonly been reported in association with acute hypertension, pre-eclampsia, eclampsia, sepsis, and exposure to immunosuppressants. Here, we report on a normotensive woman who developed a severe frontal headache, visual disturbances, and hypertension 3 days after undergoing an emergency laparotomy for ischemic colitis during which she suffered an inadvertent dural puncture. Neuro-imaging revealed features consistent with PRES. The patient went on to make a good recovery, being discharged 21 days postoperatively, with only minor visual disturbances and memory problems. This case highlights the importance of awareness of PRES to all specialties. On reviewing the literature, we feel that PRES may be a potential differential diagnosis to post-procedural neurological symptoms in those patients undergoing routine procedures such as spinal anesthetics or lumbar punctures.
