Introduction Autosomal recessive polycystic kidney disease is the most common heritable cystic renal disease occurring in infancy and childhood. The clinical spectrum of signs and symptoms of this disease is widely variable ranging from perinatal death to a milder progressive form, which cannot be diagnosed until adolescence. Case Outline A female neonate born in the 35th/36th week of gestation. The findings of all standard medical examinations of the neonate done by the mother were within normal limits. A few days before delivery physicians at a regional medical centre revealed enlarged kidneys and oligohydramnios. The delivery was performed by caesarean section. The vital functions of the newborn were in critical condition so that she was referred to the University Children's Hospital in Belgrade. Soon after admission, despite all undertaken measures, the infant died. Autopsy was done at the Institute of Pathology of the Belgrade Clinical Centre. All findings were typical for autosomal reces sive polycystic kidney disease. The kidneys were hugely enlarged, with cystically dilated collecting ducts that almost completely replaced the renal parenchyma. The lungs were mildly hypoplastic. The liver showed dilated portal spaces, with multiple irregularly branching bile ducts. The cause of death was respiratory distress and renal failure. Conclusion In all cases of congenital anomalies of the kidney with lethal ending it is necessary to perform autopsy and aimed genetic investigation.

Objective: This research aimed to determine whether an adequate surgical approach can be chosen based on clearly defined values of anatomical landmarks (tentorial angle) and tumor size and extension. Methods: We conducted a retrospective analysis of patients operated on because of pineal tumors. The cohort was divided depending on the surgical approach. On preoperative magnetic resonance imaging, we measured maximal diameters, tumor volume, and tumor propagation. In the group of patients operated with the supracerebellar infratentorial approach, we also tested the correlation of tentorial angle with residual tumor. Differences among groups in resection, complications rate, and outcome were tested by the χ2 test. Finally, in both groups, the correlation of residual tumor with tumor volume, propagation, and diameters was tested using the receiver operating characteristic curve. Results: In the group operated with a supracerebellar approach, total resection was achieved in 78% of the patients. The critical value of cranio-caudal diameter correlated with tumor residue was 31 mm, for lateral-lateral diameter 25 mm, for the lateral extension 14 mm, and tumor volume 12 cm3. Tentorial angle did not influence the extent of the resection. In the group operated with an occipital transtentorial approach, the critical tumor volume related to tumor residue was 9 mm3, anterior-posterior diameter 29 mm, and cranio-caudal diameter 28 mm. The extent of the resection was significantly higher in the supracerebellar group. Conclusions: In both approaches, tumors larger than 3 cm show an increased risk of subtotal resection. Except when most tumor volume is localized above the venous system, we advocate a supracerebellar corridor as an effective approach that is not limited by tentorial angle. © 2024 Elsevier Inc.

Introduction. Subarachnoid haemorrhage (SAH) can be followed by cardiac abnormalities. We describe a patient with Takotsubo cardiomyopathy and neurogenic pulmonary edema (NPE) after aneurysmal SAH. Case report. A previously healthy, postmenopausal woman, suffered from aneurysmal SAH with consequent hydrocephalus. After external ventricular drainage, craniotomy and clipping of the posterior inferior cerebellar artery aneurysm, the patient developed acute heart failure and NPE. Transthoracic echocardiogram showed the left ventricular apical ballooning and hypercontractile basal segments. On chest radiography, bilateral pulmonary infiltrates were seen. Seventeen days after the SAH attack, the patient was discharged from hospital. Postponed coronary angiography revealed no signs of coronary artery disease. Conclusion. This case and review of the relevant literature suggest that Takotsubo cardiomyopathy and neurogenic pulmonary edema are not uncommon after aneurysmal SAH. © 2019 Inst. Sci. inf., Univ.
