Project description:IntroductionParagonimiasis, lung fluke disease caused by infection with Paragonimus species, is a food-borne parasitic zoonosis. The overriding symptoms of Paragonimus westermani infection include chronic cough, shortness of breath, and pleuritic pain. Extrapulmonary paragonimiasis caused by aberrant parasitic migration is known to occur in a variety of sites such as the brain, abdominal wall, and intraperitoneal cavity. Ectopic paragonimiasis is an uncommon disease that presents with a few clinical manifestations, which makes it difficult to diagnose and treat.Case presentationA 47-year-old man with an unremarkable medical and surgical history presented with a peritoneal lesion that was discovered incidentally on abdominal computed tomography during routine health screening. The patient did not exhibit any associated symptoms such as abdominal pain. The radiologic diagnosis was a gastric duplication cyst and we performed laparoscopic excision of the peritoneal mass. Histopathological examination revealed paragonimiasis, and the result of the skin test for paragonimiasis was positive. The patient was treated with praziquantel.Clinical discussionThe diagnosis of ectopic peritoneal paragonimiasis remains challenging due to inexperience, misdiagnosis, and its rarity. Clinicians should bear in mind that an intra-abdominal mass may be related to a parasitic infection. The detection of the ova of Paragonimus parasites in sputum and biopsy specimens may be difficult due to an insufficient amount.ConclusionClinicians need to thoroughly take the patient's history and clinically suspect parasitic infections. Laparoscopic resection of this rare mass is safe, feasible, and allows for rapid recovery.

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:Mesothelial cyst of the spleen is a developmental disorder. Previous reports have elaborated on the radiological features of splenic mesothelial cysts as being unilocular with a smooth and well-defined margin. However, due to its rarity, it is unclear whether these characteristics are representative and specific for the diagnosis of mesothelial cysts. Herein, this case report presents an atypical case of splenic mesothelial cyst mimicking a malignant tumour, especially splenic metastasis in a 66-year-old woman with ascending colon cancer. Due to an overlapping imaging finding of hypodense splenic lesions, and considering the clinical history, a mesothelial cyst that developed as a multilocular hypodense mass from an ill-defined small nodule was inevitably misdiagnosed as metastasis. Although rare, it is important to consider the possibility of mesothelial cyst in a patient with multilocular hypodense lesions of the spleen.

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:Schwannomas are benign tumors in 95% of cases and very rarely occur in the retroperitoneum. We report the cases of a 35-year-old man with abdominal discomfort and a 50-year-old asymptomatic woman with large retroperitoneal masses. Both underwent multivisceral surgery to exclude an adrenal carcinoma, and the pathologic diagnosis showed schwannomas in both cases. Despite morphological imaging, it was not possible to get a clear diagnosis preoperatively.

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:Smooth muscle neoplasms of the vulva are rare, and when localized in the Bartholin's gland, it can be mistaken as a benign lesion leading to a delay in diagnosis. We report a case of leiomyosarcoma of the Bartholin's gland in a 63-year-old postmenopausal woman, which clinically mimicked a chronic Bartholin's gland cyst. This case report emphasizes the importance of suspecting malignancy in any vulvar lesion in women of postmenopausal age, despite its location and asymptomatic appearance. A prompt, careful evaluation with adequate clinical judgment will help to manage such cases efficiently.

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:Echinococcosis, also called hydatid disease, is a parasitic disease that passes from animals to humans. Literature reports suggest very rare cases of cerebral hydatid cysts. Brain involvement with hydatid disease occurs in 1%-2% of all Echinococcus infections. In this report, we aim to emphasize the presentation of such an isolated primary cerebral hydatid cyst, discuss its radiological features, Emergency department management, inpatient medical management, referral to neurosurgery, consequent operative procedures, postoperative care, and outcome.
