Project description:Study Design Case report and review of the literature. Objective To present an unusual case of conus medullaris ependymal cyst. Methods This is a case of a 41-year-old woman with a diagnosis of ependymal cyst who presented with a history of shock-like pain to the lower limbs. Results The patient underwent a successful cyst decompression. Conclusion A few cases have been reported in the literature. Including this case, there are a total of eight cases of ependymal cyst in the conocaudal segment reported.

Project description:Remote Cerebellar Hemorrhage is a rare entity that manifests spontaneously after supratentorial craniotomy and spinal surgeries. We present a 53-year-old male who was admitted due to subdural hematoma along the left frontoparietotemporal convexity. After treatment of the subdural hematoma with craniotomy and evacuation, he developed remote cerebellar hemorrhage 1 week later. Brain computed tomography demonstrated the zebra sign. Follow-up imaging showed complete recovery without any neurologic symptoms or signs.

Project description:IntroductionNon-parasitic spleen cyst (NSC) is a relatively rare and difficult to diagnose disease, which rapture due to a traumatic impact to the spleen, can lead to the peritonitis.Case presentationWe present the case of a 30-year-old woman with a 7.5 × 7.5 × 5 cm NSC, who underwent the microwave ablation (MWA) of the splenic cyst.ResultsThe procedure was performed under intravenous anesthesia. MWA of the cysts was performed using a probe placed in the cavity of the cyst, with the frequency of 902-928 MHz delivered during 15 minutes. The postoperative period was uneventful, and the patient was discharged after 2 days.ConclusionWe demonstrated that MWA can be utilized as a novel, minimally-invasive, and cost-effective approach in NSC treatment.

Project description:IntroductionThe cervical lymphoepithelial or branchial cleft cyst are benign dysembryologic cystic tumors developing in the anterolateral region of the neck. They are relatively uncommon anomalies.The aims of this study are to analyze the anatomoclinical features and to discuss the modalities of care for the management of this disease.Presentation of caseWe report a case of a 70 years-old woman who was admitted to our department with a complaint of painless mass in the right supraclavicular region. Clinical examination and radiological investigations found a mass compatible with cervical cyst. Treatment consisted of the complete resection of the cyst. histopathological examination found a Cervical lymphoepithelial cyst.ConclusionThe cervical lymphoepithelial can be easily misdiagnosed. It is imperative that clinicians make an accurate diagnosis for appropriate treatment (that is, surgical excision).

Project description:BackgroundNeurenteric cysts are rare congenital lesions of endodermal origin which result from the failure of the neurenteric canal to close during embryogenesis. The majority of neurenteric cysts occur in the spinal cord, though in rare instances can occur intracranially, typically in the posterior fossa anterior to the pontomedullary junction (80%) or in the supratentorial region adjacent to the frontal lobes (20%).Case descriptionWe present the case of a 75-year-old woman with an extra-axial cystic lesion centered in the premedullary cistern causing brainstem compression. The lesion was later histopathologically confirmed to be a neurenteric cyst. She presented initially with a 4-month history of worsening headache, dizziness, and unsteady gait. We performed a left retrosigmoid craniotomy for cyst fenestration/biopsy with the aid of operating microscope and stealth neuronavigation. Following the procedure, the patient recovered without complications or residual deficits.ConclusionThis case illustrates the successful fenestration of an intracranial neurenteric cyst with good clinical outcome. We present the pre- and post-operative imaging findings, a technical video of the procedure, histopathological confirmation, and a brief review of the relevant clinical literature on the topic.

Project description:Hepatic cystadenoma is an urgent problem due to the high risk of malignant transformation. There are both radical and minimally invasive methods of treatment. We present a clinical case describing the successful use of microwave ablation (MWA) in a 72-year-old woman with hepatic cystadenoma. The patient was admitted to the clinic with abdominal discomfort, dull pain in the right hypochondrium, and weight loss of 10 kg during the previous year. The patient had a past medical history of liver cyst in segment VII. Ultrasound scanning, computed tomography (CT) of abdominal organs detected an increase in the size of the cyst, heterogeneity of its structure; the contrast enhancement was noted in the cyst wall. We suspected hepatic cystadenoma in segment VII and performed cyst puncture under ultrasound control - the obtained fluid revealed the presence of cylindrical epithelial cells, mucin, and macrophages in large quantities, high telomerase activity, CA 19-9 levels were greater than 1000 U/mL. Surgery was accomplished using the MWA catheter. Biological and cytological examination of the fluid confirmed the presence of signs of liver cystadenoma with a high malignancy risk. On the 2nd day after surgery ultrasound imaging of the abdomen revealed the residual cavity of 2 × 1 cm in segment VII. The patient was discharged with recommendations to conduct ultrasound examinations every six months. The control CT scan in 2020 showed no focal or cystic formations in the liver. In what way, MWA under control of ultrasound is a promising method of biliary cystadenoma treatment with high malignancy risk.

Project description:A 49-year-old female patient, asymptomatic, presented to the cardiology office for a right atrial mass, identified incidentally in a non-electrocardiogram (ECG)-gated contrast-enhanced computed tomography, performed for follow-up of pulmonary tuberculosis. Echocardiography, surprisingly, showed an anechogenic ovoid mass in the right atrium measuring 40 × 40 mm2, implanted in the interatrial septum without affecting the tricuspid valve. ECG-gated computed tomography angiography (CTA), confirmed the dimensions of the mass, which presented homogeneous content, calcified areas, and a 12-mm pedicle implanted near the ostium of the coronary sinus. Additionally, contrast uptake and infiltration of adjacent structures were ruled out. In the surgical field, an encapsulated mass with blood content was found, which pathology reported as a hematic endocardial cyst (HEC). These are rare cardiac masses, constituting 1.5% of all primary cardiac tumors. It is usually an incidental finding, and its clinical presentation will depend on its dimensions and the intracardiac hemodynamic impact. A highlighting feature is its anechogenic content on ultrasound, however, multimodality imaging allows for making diagnostic assumptions, discerning between primary cardiac tumors, and provides morphological and hemodynamic information useful for therapeutic decision making. The age of the patient, the large size of the HEC, and its location in the interatrial septum make up a completely atypical presentation of this rare disease, which motivated this report.
