Rationale: Subarachnoid hemorrhages (SAHs) from ruptured intracranial aneurysms are very rare during pregnancy. Management of ruptured intracranial aneurysms with SAH in pregnancy is often challenging because of the risks to the fetus and the mother. We present the first successful awake endovascular coiling of a dissected intracranial aneurysm in a third trimester twin pregnancy. Patient concerns: A 28 years’ old pregnant woman was admitted at the obstetric department of our hospital on account of very severe headaches associated with nausea and vomiting. Diagnosis: Emergency obstetric ultrasound scan done confirmed 32 weeks’ twin gestation, whereas magnetic resonance imaging established hemorrhage in the suprasellar cistern and the subarachnoid space. Magnetic resonance angiography revealed a dissected aneurysm in the ophthalmic segment of the left internal carotid artery. Interventions: Awake cerebral angiography as well as embolization of the aneurysm with coils was done via the transarterial route and the twins were delivered via caesarean section at 37 weeks’ gestation. Outcomes: Two years’ follow-up indicated no complications and children as well as their mother are healthy. Lesions: Awake endovascular coiling was very beneficial in our case because we avoided general anesthesia and the use of osmotic diuretics which are potentially hazardous during pregnancy.
Rationale: Reversible posterior leukoencephalopathy syndrome (RPLS) is a clinicoradiological phenomenon first observed 2 decades ago. Reversibility is the hallmark of this rare clinical phenomenon once the triggering pathology is aptly and adequately treated. Tinnitus preceding bilateral hearing loss as a symptomatology of RPLS has not been reported in the literature. Furthermore, chronic obstructive ureteric calculus with superimposed infections as a cause of RPLS has not been reported in the literature. Patient concerns: A 57-year-old female was admitted at our facility because of 2 days history of hearing loss in both ears. She experienced tinnitus in both ears 2 weeks prior to the hearing loss. She is a known hypertensive. She has also undergone multiple surgical treatments for urinary calculi. Diagnosis: Computed tomography (CT) scan of the urinary system revealed a calculus at the right ureter. Magnetic resonance imaging (MRI) showed abnormal signals at both temporo-parieto-occipital (TPO) cortices, the subcortical area, as well as the left hippocampus which was consistent with the diagnosis of RPLS. Interventions: While on antibiotics for treatment of infections, the patient went into hypertensive encephalopathy and pneumonia was also established necessitating intensive care. Outcomes: We observed a resolution of the patient's temperature and hypertension when the right ureteric stone finally descended into the bladder. Also, we observed disappearance of the abnormal signals at both TPO cortices, the subcortical area, as well as the left hippocampus. Two years follow-up revealed no recurrence of her symptomatology. Lesions: Patients who present with hypertensive encephalopathy maybe more prone to developing RPLS. Renal insufficiency alone or hypertension alone may not be single predisposing entities to RPLS but rather multiple predisposing factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
