Project description:BackgroundIntracranial arachnoid cysts are usually benign congenital findings of neuroimaging modalities, sometimes however, leading to focal neurological and psychiatric comorbidities. Whether primarily clinically silent cysts may become causally involved in cognitive decline in old age is neither well examined nor understood.Case presentationA 66-year old caucasian man presenting with a giant left-hemispheric frontotemporal cyst without progression of size, presented with slowly progressive cognitive decline. Neuropsychological assessment revealed an amnestic mild cognitive impairment (MCI) without further neurological or psychiatric symptoms. The patient showed mild medio-temporal lobe atrophy on structural MRI. Diffusion tensor and functional magnetic resonance imaging depicted a rather sustained function of the strongly suppressed left hemisphere. Amyloid-PET imaging was positive for increased amyloid burden and he was homozygous for the APOEε3-gene. A diagnosis of MCI due to Alzheimer's disease was given and a co-morbidity with a silent arachnoid cyst was assumed. To investigate, if a potentially reduced CSF flow due to the giant arachnoid cyst contributed to the early manifestation of AD, we reviewed 15 case series of subjects with frontotemporal arachnoid cysts and cognitive decline. However, no increased manifestation of neurodegenerative disorders was reported.ConclusionsWith this case report, we illustrate the necessity of a systematic work-up for neurodegenerative disorders in patients with arachnoid cysts and emerging cognitive decline. We finally propose a modus operandi for the stratification and management of patients with arachnoid cysts potentially susceptive for cognitive dysfunction.

Project description:BackgroundPericardial cysts are rare congenital mediastinal cysts. They are typically asymptomatic and are often discovered incidentally, although some patients may present with chest pain and dyspnoea. Asymptomatic patients are managed conservatively with multiple modalities, with surgical resection often recommended for symptomatic patients only. The frequency of follow-up imaging has yet to be established.Case summaryWe report a case of a 59-year-old female with a gradually increasing pericardial cyst, first noted 10 years prior as an abnormal cardiac silhouette on routine chest radiography. Further evaluation confirmed the presence of a pericardial cyst compressing the left ventricle with new-onset atrial fibrillation. The patient underwent successful thoracoscopic excision of the pericardial cyst under general anaesthesia. The patient's post-operative course was uneventful, and she was ultimately discharged in stable condition.DiscussionPericardial cysts are typically benign, but complications may arise in the case of compression of adjacent cardiac structures, inflammation, haemorrhage, or rupture of the cyst. Magnetic resonance imaging is considered the better modality for both diagnosis and follow-up of pericardial cysts. This case illustrates the need for long-term clinical follow-up in order to optimize the time for treatment.

Project description:Introduction A nasolabial cyst is an ectodermal development cyst. It presents as a fullness of canine fossa, nasal ala, or vestibule of the nose. It is rare and usually small. Treatment consists of complete surgical excision or transnasal endoscopic marsupialization. Objective To describe a giant nasolabial cyst case treated using Neumann incision. Case Report A 37-year-old man was referred to the otolaryngology department with nasal obstruction and nasal deformity. Computed tomography showed a nasal cystic lesion 4 × 4.5 × 5 cm wide. Surgical excision using Neumann incision was performed. Discussion Neumann incision provides wide access to the nasal cavity and may be useful in nasolabial cyst treatment.

Project description:BackgroundWe report on a 21-year-old patient with a giant symptomatic hydatid cyst of the interventricular septum, to whom a staged management approach was employed. Induction medical therapy led to a reduction in the size of the cyst, which was then completely removed via surgical excision.Case presentationA 21-year-old male Caucasian, with main complaints of fatigue and palpitations, was referred to our Centre due to a cystic formation in his left ventricle. The workup consisted of transthoracic echocardiography and cardiac magnetic resonance, which revealed a huge hydatid cyst in an active stage of disease, occupying the basal and mid part of the interventricular septum. Due to the size of the lesion and lack of viable myocardium in the affected area, the patient was declared inoperable and medical therapy was initiated. Serial echocardiography revealed a significant reduction in the size of the lesion and degradation to transitional and inactive stage, after which successful surgical excision of the cyst was performed. In the course of the medical treatment, the patient experienced sustained ventricular tachycardia causing loss of consciousness, which did not reoccur after surgical excision.ConclusionMedical therapy can result in the degradation of a giant heart hydatid cyst, enabling surgical excision. Heart hydatid cyst can lead to potentially lethal arrhythmia irrespective of its size and stage, which does not reoccur after successful surgical excision.

Project description:IntroductionIncidental durotomy is a relatively common complication of spine surgery. Prevalence ranges from 3 to 5% in primary and 7 to 17% in revision procedures. Despite this relatively common occurrence the subsequent development of pseudomeningoceles following lumbar spine surgery is reported to be between 0.07 and 2%. Giant pseudomeningoceles (GP) are rare and therefore we report our experience with a case.Case presentationWe report a case of an iatrogenic GP post revision lumbar surgery that extended 19?cm in length. The patient underwent revision L3-S1 laminectomy, laminotomy, excision of pseudomeningocele and successful direct dura repair. Postoperatively, a subcutaneous seroma persisted. This was managed with surgical exploration and prolonged drainage. This led to reduction of the seroma and symptomatic improvement for the patient.DiscussionIncidental durotomy is a relatively common complication of spine surgery and if the durotomy is not addressed at the time of an operation a pseudomeningocele may develop. A pragmatic approach for GP is to individualise management based upon symptoms. Although GP are rare, prevention is likely the best approach. We outlined a structured approach to the management of an incidental dural leak that formed the largest reported pseudomeningocele reported to date.

Project description:BackgroundExtensive studies have been performed about the synovial cyst and intraspinal extradural ganglion cyst. Here, we describe a new type of the cyst with entirely different histological characteristics, which we are now calling a "Spontaneous Degenerative Epidural Cyst."Case descriptionA 74-year-old male presented with low back pain, bilateral lower extremity radiculopathy, and a cauda equina syndrome. He exhibited a partial left foot drop (Grade 3/5) and hypoesthesia in the sacral region. The magnetic resonance imaging (MRI) showed two cysts at the L4-L5 level; Cyst I was in the left foramen and Cyst II was within the epidural space between the dura and ligamentum flavum. Cyst I was removed through an endoscopic transforaminal approach; it originated from the left facet joint and with synovial lining was confirmed to be a synovial cyst. Cyst II required an endoscopic interlaminar approach, and pathology revealed granulation tissue with micro-calcification, woven bone formation, hemosiderin pigment, and focal cystic change consistent with our designation "Spontaneous Degenerative Epidural Cyst."Conclusion"Spontaneous Degenerative Epidural cyst" should be considered among the differential diagnostic consideration for the different lumbar cysts. High-resolution MRI is the most useful in diagnosing these lesions, while full endoscopic treatment provides for adequate resection of these lesions.

Project description:IntroductionPericardial cysts are considered as a rare congenital abnormality, mostly found incidentally. The estimated incidence of pericardial cyst is 1:100,000 and represent approximately 6% of all mediastinal masses. Patients can present with symptoms similar to acute chest pain or right-sided heart failure or can be asymptomatic.PresentationA 46-year-old female who is known to have hypertension and hypothyroidism presented to the breast clinic with left breast mass that was proved by core needle biopsy as proliferative breast lesion. During the preoperative assessment, the patient reported progressive shortness of breath and cough over the last two years and bilateral lower limb edema. Her preoperative chest X-ray showed a well-defined oval like opacification at the right cardiophrenic angle that was proved by chest computed tomography imaging as a cystic mass od most likely a pericardial origin. A huge pericardial cyst originating from the right diaphragmatic surface was excised through a mini-sternotomy incision with smooth postoperative recovery. The patient-reported significant improvement in her symptoms and her lifestyle during her follow up.DiscussionPericardial cysts represent 6%-7% of all mediastinal masses with an estimated incidence of 1:100,000. About 70% of pericardial cysts originate at the right cardiophrenic angle and less frequently at the left cardiophrenic angle, they are usually suspected when the chest x-ray shows an enlarged contour of the right heart border. Mediastinal cysts have many differential diagnoses and the preoperative decision might be challenging in many cases. Pericardial cysts appear as oval, thin-walled homogeneous masses on cardiac computed tomography. The choice between surgical intervention and conservative follow up is related mainly to the size and symptoms that are induced by the cyst.ConclusionAs pericardial cysts are rarely diagnosed pathology, a high index of suspicion is essential for diagnosis. Surgical resection is indicated when they are huge, enlarging in size or symptomatic. Morbidity and mortality risks following pericardial cyst excision are very low.

Project description:Spleen is an unusual location for hydatid cyst. Here we report a case of primary splenic hydatid cyst in a 41-yr-old Iranian woman from Yasuj, southwest of Iran. The patient had been admitted to Shahid Beheshti Hospital because of abdominal pain. Abdominal sonography revealed a hypoechoic lesion of 150 X 130 mm in the spleen, suggestive of hydatid cyst. Splenectomy was performed for the patient and surgical interventions revealed a hydatid cyst occupying most of splenic parenchyma. She was discharged on the 5 day of her operation. Postoperative diagnosis and confirmation of hydatid cyst was done by histopathological, molecular and serological approaches. Histopathological evaluation revealed the classical laminated layer of hydatid cyst. DNA was extracted from a part of cyst and PCR amplified. Sequencing and analysis of PCR product revealed that the isolate has the most similarity with G1 strain of Echinococcus granulosus. Patient's serum was positive for IgG anti-hydatid cyst antibodies, using antigen-B ELISA.
