Immediately after a fine-needle aspiration biopsy (FNAB) was performed of a carcinoid liver metastasis, a patient had severe flushing, nausea, and faintness, followed by generalized seizure activity, profound hypotension, and cardiopulmonary arrest refractory to resuscitative efforts. This was considered due to massive release of vasoactive substances into the systemic circulation, caused by manipulation of the tumor at biopsy and aggravated by resuscitative efforts. Hypotensive crisis should be considered a potential, although unusual, complication of FNAB of liver metastases in patients with carcinoid syndrome. If biopsy is necessary, an intravenous access line should be established before biopsy is performed, and personnel should be prepared to administer emergency resuscitation. Medication with a somatostatin analogue before biopsy is performed is suggested. Catecholamine administration should be avoided.

Untreated hyperthyroidism during pregnancy is associated with increased maternal and perinatal morbidity. Some features of this disease simulate preeclampsia, which may encourage delivery of the fetus. We report a case of poorly controlled hyperthyroidism associated with generalized seizures, where patient management was directed at a diagnosis of preeclampsia-eclampsia. Although the presence of eclampsia and marked hyperthyroidism is very rare, this case illustrates the importance of aggressive medical management of hyperthyroidism. A 17-year-old gravida was diagnosed with hyperthyroidism at 15 weeks' gestation. At 26 weeks' gestation, she was admitted to the hospital after noting edema of the upper and lower extremities, nausea, vomiting, shortness of breath, and a cough. At admission, she was hypertensive, tachycardic, and dyspneic. The patient was believed to have preeclampsia with pulmonary edema complicated by hyperthyroidism. We initiated magnesium sulfate therapy and administered several bolus doses of hydralazine, with little effect on blood pressure. Oliguria was noted, and a pulmonary artery catheter was inserted. Hours later, generalized seizure activity occurred, and a decision was made for abdominal delivery. Postoperatively, cardiovascular function stabilized. On postoperative day 3, we received the results of the thyroid function tests obtained at admission, which suggested a markedly hyperthyroid condition. Untreated or poorly treated hyperthyroidism may present a clinical picture similar to preeclampsia. In our case, both disease processes coexisted in their severest forms. It is possible, although completely unproven, that a relationship exists between poorly controlled hyperthyroidism and preeclampsia-eclampsia. More importantly, accurate diagnosis of hyperthyroidism should lead to prompt medical or surgical management, thereby decreasing maternal and perinatal morbidity.

Central nervous system (CNS) - related symptoms occur in haemorrhagic fever with renal syndrome (HFRS). To study the CNS and ophthalmic involvement in nephropathia epidemica (NE), the European type of HFRS, we included 26 patients in a prospective study. Most common CNS-related symptoms were headache (96%), insomnia (83%), vertigo (79%), nausea (79%), and vomiting (71%). Ophthalmic symptoms were reported by 82% of patients; 41% had photophobia and 50% had impaired vision. A transient loss of vision was recorded in one patient, who also had a generalized seizure. Minor white matter lesions were found in about half of the patients investigated with brain magnetic resonance imaging (MRI). Electroencephalography (EEG) showed severe alterations in only one patient, and slight and reversible patterns in another two patients. Neopterin, interleukin-6 and interferon-gamma levels in the cerebrospinal fluid (CSF) were elevated, which may indicate immune activation. However, we found no evidence of intrathecal NE virus replication. We conclude that CNS-related symptoms are common in NE, and transient ophthalmic involvement can be demonstrated in about half of the patients.

Hypomagnesaemia as a primary cause of a generalized seizure is uncommon. A 60-year-old woman with Crohn's disease, who had had recent small bowel surgery and a total colectomy 10 years previously, was admitted complaining of severe nausea, vomiting, fatigue and thirst. Despite oral magnesium therapy she had a generalized seizure due to severe hypomagnesaemia of 0.09 mmol/l (normal range 0.65 to 1.05 mmol/l). Her serum calcium was 1.91 mmol/l (2.03 to 2.63 mmol/l). Hypomagnesaemia can cause generalized convulsions but is usually associated with hypocalcaemia. This patient had an almost normal serum calcium level, and therefore hypomagnesaemia would seem to have been the direct cause of her seizure. Long-term intravenous magnesium was necessary to prevent further seizures.

Laparoscopic Roux-en-Y gastric bypass (LRYGBP) has been an available operation for weight loss for the past decade, and bariatric surgery is increasing in the United States. Careful patient screening and follow-up have been the cornerstone for success against the complexities of morbid obesity. Neurologic complications have occurred, such as polyneuropathy and Wernicke-Korsakoff syndrome. We report an 18-year-old female with morbid obesity, steatohepatitis, tobacco, recreational drug, and oral contraceptive use who at 4 months after LRYGBP experienced a generalized seizure and stroke. She was diagnosed with an acute ischemic stroke, possibly venous infarction. Her postoperative course had been complicated by malnutrition and dehydration, apparently related to nausea from chronic cholecystitis. She had a possible protein-S deficiency. Rare neurologic complications emphasize the importance of postoperative surveillance in these patients.

A 29-year-old woman was admitted to our hospital with a 7-day history of elevated temperature to 39.5 degrees C associated with headache and nausea. She had been diagnosed with tuberous sclerosis complex 10 years earlier. Her unconsciousness progressed, and she was diagnosed as having aseptic meningoencephalitis. The next day, she had a generalized seizure with severe hemoptysis, and she suddenly fell into severe respiratory failure (PaO2/FiO2 = 76.9). Transbronchial lung biopsy revealed the findings of lymphangioleiomyomatosis. It was suggested that neurogenic pulmonary edema accompanied with venous flow obstruction by lymphangioleiomyomatosis lesions resulted in diffuse pulmonary hemorrhage with resultant gross hemoptysis accelerating to severe hypoxemia.

Hyponatremia is a significant complication of treatment with serotonin selective reuptake inhibitors (SSRI). We describe a case of a 53-year-old woman that was started on fluoxetine 20 mg/day for depression. Nine days later, the patient started with weakness, nausea, progressing to confusion, inappetence and vomit. Three hours later she became unresponsive and had a generalized seizure. She was brought to our emergency service. On admission, the patient was normovolemic, without focal motor deficits, but had mild generalized muscle rigidity and Babinski's sign bilaterally. Serum sodium was 105 mmol/L, serum osmolality, 220 mmol/L, and urinary osmolality, 400 mmol/L. The other laboratory exams, chest X-ray, cerebrospinal fluid and cranium tomography were normal. She was found to have fluoxetine-induced SIADH and it was discontinued. We started the hyponatremia correction and, in 5 days, the mental status of the patient gradually returned to a normal baseline, paralleling the resolution of her hyponatremia, without recurrence. Hyponatremia and SIADH should be considered if a patient experiences deterioration in his or her clinical condition while taking SSRI. The use of SSRI antidepressants should be remembered in the differential diagnosis of drug-induced hyponatremia.

Giant cavernous hemangiomas occur very rarely, and little has been reported about their behavior. In this case report three cavernous hemangiomas with a diametric measure between 6 cm and 7 cm and distinct features will be described. A 36-year-old female patient presented with headache and nausea. A CT scan disclosed a large circumscribed tumor with strong contrast enhancement in the temporo-parieto-occipital region of the right cerebral hemisphere and extension into the right cerebellar hemisphere. A 35-year-old woman was admitted to our emergency ward with a generalized seizure and a dilated pupil. The CT scan showed an extensive left frontal lesion containing a substantial hyperintense part, suspicious for hemorrhage. A 3-year-old girl was admitted with generalized seizure and progressively declining consciousness. A large left frontotemporal paraventricular multi-cystic lesion was encountered on the CT scan. All three patients were operated on. Two recovered very well. In the case of the 3-year-old girl stable disease was reached. Giant cavernomas do not differ from average-sized cavernomas in clinical, surgical or histopathological presentation but may differ radiologically. However, the possible diagnosis of cavernoma can be overlooked, due to their size and possible differential diagnosis.

Postpartum onset of eclampsia and HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome is a rare but life-threatening complication for both mother and fetus. A case of a 38-year-old parturient (gravida 2, para 1) who was asymptomatic prior to delivery is reported. Emergency caesarean section had to be performed due to sudden onset of fetal bradycardia as a result of partial placental separation. The perioperative course was characterized by new onset hypertension, nausea and restlessness; within 2 h the patient suffered a generalized seizure which was treated with magnesium sulfate and hydralazine. Despite management in accordance with current guidelines, the condition deteriorated with hypotension, anemia and renal failure. On further examination hematomas in the abdominal cavity and walls were identified and laboratory tests confirmed HELLP syndrome with severe coagulopathy. Explorative laparotomy revealed diffuse bleeding without a significant isolated source or postpartum uterine hemorrhage. Retrospectively, the anemia could be ascribed to severe hemolysis and diffuse bleeding from coagulopathy. The patient required packed red cells, platelets, fresh frozen plasma and prothrombin complex. After admission to the intensive care unit persistent diffuse bleeding mainly caused by hyperfibrinolysis and renal failure occurred, which required blood transfusion, antifibrinolytic (tranexamic acid) and renal replacement therapy (continuous veno-venous hemodiafiltration with citrate) for 6 days. The patient recovered without any sequelae and was discharged 26 days later. Placental separation with new onset peripartum hypertension is to be interpreted as a precursor of severe gestosis and associated complications, especially disseminated intravascular coagulation (DIC), acute renal failure and pleural effusion. A differentiation between a rapid drop in hemoglobin concentration secondary to hemolysis in postpartum HELLP syndrome rather than postpartum hemorrhage can be challenging. In addition, HELLP syndrome can lead to rapidly developing, fulminant hyperfibrinolysis in the context of DIC. Keys to successful management of postpartum gestosis and associated complications are early detection and perception of clinical and laboratory warning signs, a multidisciplinary approach with rapid and consistent targeted symptomatic therapy to save the mother and fetus.

We report a rare case of cisplatin-induced acute hyponatremia leading to a seizure and coma. A 66-year-old woman with breast cancer received adjuvant chemotherapy with docetaxel and cisplatin. She had no nausea, vomiting, or diarrhea during or after chemotherapy administration. She had an acute onset of a generalized seizure and coma on the fourth day after chemotherapy. On arrival in the emergency department, she was unconscious with a Glasgow Coma Score of 6 (eyes 1, verbal 1, motor 4). Computed tomography of the brain did not show any lesions. She had no underlying diseases except breast cancer. The laboratory studies showed severe hyponatremia (Na 113 mmol/L) with low plasma osmolality, and elevation of both urinary sodium and urinary osmolality. In addition, polyuria (about 4 L/day) was also noted. Her consciousness level gradually improved the next day with a rise in serum sodium after 3% NaCl infusion. She recovered fully with no sequelae. Assessment using the Naranjo probability scale suggested that cisplatin was the probable cause for the adverse event. The mechanism of hyponatremia induced by cisplatin in our case was thought to be renal salt wasting syndrome (RSWS). In conclusion, cisplatin-induced acute hyponatremia leading to seizures and coma is seen rarely. When RSWS is suspected, hypertonic saline should be administered.
