How to Perform a Giant Parameniscal Cyst Exeresis: Step by Step Technique.

ABSTRACT: Parameniscal cysts are usually small cystic lesions, less than 2 cm in size, found along the meniscal periphery. They are rarely associated with extra-articular palpable mass. Magnetic resonance imaging is the diagnostic method of choice; giant meniscal cysts (>5 cm at its greatest diameter) are very rare, with few cases described in the literature. We describe a step-by-step open exeresis and arthroscopic meniscal suture technique for the treatment of a 9-cm giant parameniscal cyst located on the lateral side of the knee. Treatment of giant meniscal lesions requires caution during dissection and exeresis. Because acute meniscal lesions benefit from meniscal suture rather than meniscectomy, horizontal degenerative lesions may also present excellent results with repair techniques. We conclude that the combination of the open excision of the giant cyst with careful dissection and protection of neurovascular structures, combined with the arthroscopic meniscal suture, is a good strategy to approach such lesions.

Complete Surgical Enucleation of a Giant Chylous Mesenteric Cyst.

Project description:Mesenteric cysts are rare benign abdominal tumors, and they can appear anywhere in the mesentery of the gastrointestinal tract, from the duodenum to the rectum. They are generally asymptomatic and may present as an incidental finding. The diagnosis is confirmed by the laparotomy findings and the results of the histopathological examination. Complete surgical (open or laparoscopic) enucleation of the cyst is the treatment of choice. We present a case of a female patient who presented with abdominal pain and a giant palpable abdominal mass. The patient underwent a surgical exploration which showed a giant mesenteric cyst. A complete surgical enucleation of the cyst was successfully performed without the need of bowel resection. The histopathological examination of the cyst was compatible with the diagnosis of chylous mesenteric cyst.

Giant Retrorectal Epidermoid Cyst Masquerading as a Perianal Swelling.

Project description:A retrorectal epidermoid cyst is an uncommon congenital lesion that arises from the remnants of the embryonic tissues. This type of cyst is difficult to diagnose before surgery. In this study, we report a rare case of a giant retrorectal epidermoid cyst in a 30-year-old woman. Initially, the condition was diagnosed as a perianal abscess and treated with incision and drainage. Since the abscess recurred, a pelvic magnetic resonance imaging was ordered, which revealed an 8.2?cm perianal cyst with appearance not compatible with an abscess. Postsurgical histologic analysis confirmed a retrorectal epidermoid cyst. Postoperative course was uneventful, and the woman was discharged on postoperative day 3. She was doing well at 4 months of follow-up. This report suggests that retrorectal cysts should be considered in cases of recurrent perianal swellings/abscesses.

Case report: a giant arachnoid cyst masking Alzheimer's disease.

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.

Surgical resection of a giant pericardial cyst: a case report.

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.

First case report of ruptured giant expanding breast oil cyst.

Project description:BackgroundFat necrosis is a common sequelae of breast trauma. Its many presentations have been described in the literature. Oil cyst is one of the less common presentations of fat necrosis. Giant oil cyst is rare and may take many years to mature in an unstable environment of the women's breast. To our best knowledge, rupture of a giant oil cyst has never been reported. Yet, it should be included on the list of differential diagnoses along with hematoma, infection, or neoplasm. When a patient presents with an expanding breast lump, clinicians should be aware of the potential for oil cyst rupture and its features.Case descriptionA 51-year-old woman presented to a breast clinic with concern of an expanding painless left breast lump for the last 4 months. The lump first appeared 12 years ago shortly after a car accident and was stable for many years. The initial left breast ultrasound was inconclusive, but diagnostic mammogram revealed a giant ruptured calcified oil cyst. Due to the availability of prior diagnostic images, we were able to retrospectively follow the unique sequelae of fat necrosis from the development of giant oil cyst shortly after the breast trauma and up to the final outcome of ruptured calcified oil cyst.ConclusionsTrauma to a woman's breast can lead to the formation of a large oil cyst which can remain present for years, peripherally calcify, and is susceptible to rupture. Clinicians should be aware of this potential complication when presented with the case of expanding breast lump. Diagnostic mammogram is a study of choice and demonstrates benign pathognomonic features of an oil cyst.

Imaging diagnosis of a giant choledochal cyst in an infant.

Project description:The usual etiologies of giant abdominal cystic masses in infants are mesenteric cyst, enteric duplication cyst, ovarian cyst in females, cystic lymphangioma, however, the presentation of a choledochal cyst in a gigantic form, is unusual. The primary modality for diagnosis of this entity is ultrasound, followed by MRI. The characteristic ultrasound features of a choledochal cyst are a well-defined cystic lesion which may be found to replace any segment of the biliary tree and is distinctly separate from the gallbladder. The associated anomalies are biliary atresia, gallbladder atresia, hepatic fibrosis and those of the pancreatico-biliary ductal system. MRI with MRCP has a conclusive role in confirming the ultrasound diagnosis. Choledochal cysts are currently classified as proposed by Todani et al, into five types. Herein, we report the case study of a 4-month-old male infant afflicted with a gigantic, Type1 Choledochal cyst, complicated by perforation, which was diagnosed by us at the first instance itself, using ultrasound examination and confirmed by MRI. The diagnosis was further confirmed at surgery and histopathology. The recommended treatment of cyst resection accompanied by a hepatico-jejunostomy bypass procedure, was successfully performed in the reported infant.

Staged management of a giant cardiac hydatid cyst: a case report.

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.

Primary Giant Cerebral Hydatid Cyst in an 8-year-old Girl.

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.

Two-Portal Endoscopic Plantar Fascia Release: Step-by-Step Surgical Technique.

Project description:Plantar fasciitis is a common condition of heel pain with a lifetime incidence up to 10%. For this entity, conservative treatment is considered the gold standard, involving non-steroidal anti-inflammatory drugs, stretching exercises of the plantar fascia, activity modifications, ice, and insoles. When patients do not respond to these treatments, partial or total plantar fascia release has been the mainstay of treatment, with success rates of approximately 70% to 90%. For this purpose, several techniques have been described, including open, percutaneous, and endoscopic release. The objective of this Technical Note is to describe the nonassisted 2-portal endoscopic plantar fascia release in a patient with recalcitrant plantar fasciitis.
