An unusual case of synovial cyst of the hip joint presenting as femoral vein compression and severe lower limb edema

Epidemiology, clinical manifestation, diagnosis,and treatment of bursitis iliopectinea: A systematic review

Background

Bursitis iliopectinea (BI) is a condition that is characterized by swelling of the iliopsoas bursa, leading to compression of inguinal neurovascular structures, causing swelling, pain, paresthesia, or thrombosis of the leg.

Questions

Due to the rare occurrence of BI, the available literature consists of case reports. Our study aims to systematically review the literature for a comprehensive analysis of the etiology, treatment modalities, and clinical outcomes of patients with BI.

Methods

We systematically analyzed 217 studies with 502 cases of BI and extracted information about the terminology, risk factors, diagnostic and treatment strategies, association with neurovascular compression syndromes, treatment outcomes, and recurrence rates.

Results

The overall quality of the analyzed studies was moderate to good. The terminology uses for BI was heterogeneous and included ganglion, tumor, mass, and bursitis. In addition to conventional X-ray, ultrasound, CT, or MRI were used to diagnose BI. The most prevalent etiology of BI was osteoarthritis of the hip or wear-related soft-tissue reactions after total hip replacement (THA). Nearly one-third of the patients suffered from compression syndromes, most frequently of the femoral vein (16%). Only rheumatoid arthritis showed an association with the occurrence of compression syndromes. The most common operative treatments were the resection of the bursa (30%), total hip arthroplasty (29%), and aspiration (24%). Use of analgesics (17%), injection of corticoids (11%), and physiotherapy (9%) were used for conservative treatments. The recurrence rate was highest after physiotherapy (OR: 4.1) or aspiration (4.5) and lowest after THA (OR: 0.2).

Conclusions

Although BI is a condition commonly associated with hip arthritis or local tissue reactions following total hip prosthesis, its impact extends beyond typical hip-related symptoms. Notably, BI related to rheumatoid arthritis shows a high correlation with neurovascular compression symptoms, with femoral vein compression being the most frequently reported. This underscores the necessity of considering BI in patients presenting with nonspecific inguinal pain or neurovascular symptoms of the lower extremity. Additionally, standardizing the nomenclature of BI nomenclature could improve future research.

Dual culprit for a swollen leg: Femoral vein compression caused by lymphadenopathy and a synovial cyst

A young man had presented to the clinic with unilateral leg swelling with concerns for deep vein thrombosis. Imaging studies revealed external compression of the left common femoral vein due to enlarged lymph nodes and a cystic structure in the left groin. He underwent surgical exploration with resection of multiple compressive lymph nodes but continued to remain symptomatic. He underwent reexploration of his groin to remove a cystic structure posterior to the vein, with complete resolution of his symptoms. The enlarged lymph nodes were reactive, and the cyst was consistent with a synovial cyst on pathologic examination. Complete resection is warranted when exploring the causes of external venous compression.

An unusual case of hip pain after total hip arthroplasty: A case report

Our goal is to draw attention to the inflammation of the iliopectineal bursa being a rare condition, which can cause lower limb swelling and anterior pain of the hip even years after total hip arthroplasty. A 67-year-old woman was admitted seven years after hip arthroplasty (cemented total endoprosthesis [TEP]) with swelling and feeling of excessive fullness of the lower extremity and with tolerable anterior hip pain. The physical examination and blood tests were non-specific for septic condition. Ultrasound showed a cystic mass in the inguinal region with a direct contact to the common femoral vein. Deep vein thrombosis was excluded. The single-photon emission computed tomography-computed tomography (SPECT-CT) was administered to decide the surgical plan, either making a bursa extirpation or making revision hip arthroplasty. The SPECT-CT excluded the possibility of aseptic loosening. Methylene blue was injected into the bursa intraoperatively which did not enter the strong pseudo-capsule of the joint and, therefore, we did not administer revision of the TEP, and the bursa was extirpated. Two weeks after the operation, the patient had no pain, was able to walk, and the swelling decreased. Four months after surgery, the pain and feeling of fullness disappeared, with minimal lower limb swelling. In conclusion, in case of increasing complaints of patients who left years behind without any problem following total hip arthroplasty, the pathogenic role of the iliopectineal bursa should be taken into account, after excluding more frequent causes such as aseptic loosening or periprosthetic joint infection. As long as we consider about a rare disease, we can find a solution to the patient's complaint sooner.

Minimum 5-year follow-up of arthroscopic treatment of symptomatic iliopectineal cyst

INTRODUCTION

We aimed to primarily assess the clinical and functional outcomes of arthroscopic treatment of the symptomatic iliopectineal cyst at a minimum 5-year follow-up. Our secondary objective was to document the technical nuances of our arthroscopic technique.

METHODS

A retrospective review of chart data was performed for 30 patients who underwent arthroscopic treatment of a symptomatic iliopectineal cyst in the period between 1999 and 2015. The mean age of our patients was 57 (33-78) years. All patients completed a minimum follow-up period of 5 years. Our clinical outcomes were assessed by 100 mm VAS for pain, recurrence rate and complications. Functional outcome was evaluated by the modified Harris hip score (mHHS). Patients were asked their level of satisfaction with surgery on a scale of 0-10.

RESULTS

In all patients, the valve mechanism of the iliopectineal cyst could be released arthroscopically and the cyst could be completely evacuated. The preoperative symptoms disappeared within 3-6 weeks after the arthroscopic intervention. Patients showed significant improvement in VAS and mHHS 6 months postoperatively and at final follow-up. The average patient satisfaction was 9.2 at 6 months postoperative and 7.9 at final follow-up. None of our patients experienced any complications. At the final follow-up, there was neither clinical nor radiological evidence of cyst recurrence.

CONCLUSIONS

Arthroscopic treatment of the iliopectineal cyst is a feasible and safe alternative to open surgery resulting in significant improvement of clinical and functional outcomes.

Inconsistent Use of Terminology and Different Treatment Outcomes of Venous Adventitial Cystic Disease: A Proposal for Reporting Standards

Adventitial cystic disease (ACD) is a very rare condition characterized by the accumulation of a cyst filled with gelatinous substance in the adventitia of a vessel adjacent to the joint area. The cyst usually compresses the vessel lumen, causing claudication or leg swelling. The disease usually affects the popliteal artery. However, several cases of venous ACDs particularly in the common femoral or external iliac vein have been reported. The definition, diagnosis, and optimal treatment of ACD remain controversial because of its rarity and the inconsistent use of terminology. The heterogeneity of the reported cases is more prominent in venous ACD. Herein, the accurate terminology of cysts correlated to the joint (synovial cyst, ganglion cyst, and adventitial cyst) and the pathogenesis, anatomy, and optimal therapy of venous ACD are discussed in detail to establish reporting standards for future studies.

External iliac vein compression and lower-extremity swelling caused by an iliopectineal ganglion: a case report

Background

A hip joint ganglion is a rare cause of lower-extremity swelling.

Case presentation

We report a case of a Japanese patient with ganglion of the hip with compression of the external iliac/femoral vein that produced signs and symptoms mimicking those of deep vein thrombosis.

Conclusions

Needle aspiration of the ganglion was performed, and swelling of the lower extremity promptly decreased. At 7.5 years after aspiration, there was no recurrence of swelling of the leg. Although the recurrence rate for ganglions after needle aspiration is high, it is worthwhile trying aspiration first.

Synovial cysts of the hip joint: a single-center experience

BACKGROUND

Synovial cyst of the hip joint is a rare clinical condition in need of evidence-based guidelines for its diagnosis and management. Normally, synovial cyst of the hip joint requires no treatment, but when it intrudes into surrounding structures, various clinical symptoms appear. Because of its rarity, a symptomatic synovial cyst is often confounded with a tumor as a space-occupying lesion or with other diseases, depending on its various clinical presentations. Therefore, guidelines for the precise diagnosis and appropriate management for synovial cyst of the hip joint are required.

METHODS

We retrospectively studied 7 cases of symptomatic synovial cyst of the hip joint, some of which showed lower limb edema due to mass effect. We compared physical exam findings on presentation, imaging findings, and size and location of the cyst.

RESULTS

All cases were managed successfully with surgical excision. We found that, instead of the size of the cyst, the location of the cyst was an important contributor to venous compression. The recurrence rate was 0%, and some patients have significantly long follow-up of 2 years, 4 years, 6 years and 10 years, respectively.

CONCLUSIONS

For symptomatic synovial cyst of the hip joint, surgical excision can successfully resolve the symptoms without recurrence. This retrospective study discusses the clinical presentations, diagnostic approaches, and surgical treatment of symptomatic synovial cyst of the hip joint, hence shedding more light on the clinical management of this condition.

Diagnosis and surgical treatment of patients with femoral vein compression from hip joint synovial cyst

OBJECTIVE

In this study, the diagnosis and treatment of patients with femoral vein compression from a synovial cyst of the hip joint were investigated.

METHODS

A retrospective study was conducted to review hospital records from March 2010 to July 2017 of patients with femoral vein compression from a synovial cyst of the hip joint. The diagnostic procedure, duplex ultrasound results, computed tomography (CT), and magnetic resonance imaging (MRI) were recorded. The method and treatment outcomes were also documented.

RESULTS

Fifteen patients with femoral vein compression resulting from a synovial cyst of the hip joint were identified. The mean age was 47.5 years, and nine of the patients (60%) were female. All patients had unilateral lower extremity edema. In 11 patients (73.3%), the mass in the groin area could not be palpated; 2 (13.3%) patients had venous insufficiency; and 2 (13.3%) patients had venous thrombosis. All patients received a duplex ultrasound examination, 4 (26.7%) patients received CT, and 11 (73.3%) patients received MRI. One patient received a duplex ultrasound-guided percutaneous needle aspiration; however, the cyst recurred 1 month later. The remaining 14 patients received surgical excision and had no cyst recurrence during the follow-up period (mean, 22.6 months).

CONCLUSIONS

Duplex ultrasound should be selected as the first choice for screening of synovial cyst of the hip joint with femoral vein compression. Moreover, it can be used as the first choice for follow-up of these patients. MRI or CT can provide more anatomic information for surgical treatment. Surgical excision of the cyst is the preferred treatment method, with a lower rate of cyst recurrence compared with needle aspiration.

Synovial cysts of the hip

Background:

Synovial cysts of the hip are relatively rare lesions comparing to other joints. Patients are usually asymptomatic, but in some cases symptoms such as pain and/or compression of vessels or nerve could be present. Purpose of the study was to define clinical features and optimal management of synovial cyst of the hip joint through an accurate review of the literature.

Methods:

We present three consecutive cases treated with three different therapeutic strategies: surgical excision, wait-and-see and needle aspiration. An accurate review of the literature has been performed to identify patients who had been treated for synovial cyst of the hip.

Results:

Due to the rarity of the disease, there are no significant data in literature supporting the gold standard of treatment. Treatment of the synovial cyst depends on their size, symptoms and comorbidities.

Conclusions:

Most of the Authors recommend surgical treatment for symptomatic synovial cysts and needle aspiration as an option treatment in asymptomatic patients without vessel or nerve compression. In patients that referred symptoms in correspondence with the hip joint, not strictly related with radiograph findings, a CT or MRI examinations should be performed to exclude possible differential diagnosis.

Cystic Disease of the Groin Presenting as Compression of a Femoral Vessel

In this study, we describe our diagnosis and treatment of two patients who presented with femoral vessel compression caused by a cystic lesion in the groin. One case was diagnosed as adventitial cystic disease (ACD) of the common femoral artery resulting in leg claudication and the other was diagnosed as a ganglion cyst (GC) causing femoral vein compression and unilateral leg swelling. The operative findings differed between these two cases with respect to the dissection of the cyst and femoral vessel, but the postoperative histological examination results were similar. The pathogenesis of ACD and GC is not fully understood, and further investigation is needed to delineate the exact pathology of these uncommon conditions.

A Huge Capital Drop with Compression of Femoral Vessels Associated with Hip Osteoarthritis

A capital drop is a type of osteophyte at the inferomedial portion of the femoral head commonly observed in hip osteoarthritis (OA), secondary to developmental dysplasia. Capital drop itself is typically asymptomatic; however, symptoms can appear secondary to impinge against the acetabulum or to irritation of the surrounding tissues, such as nerves, vessels, and tendons. We present here a case of unilateral leg edema in a patient with hip OA, caused by a huge bone mass occurring at the inferomedial portion of the femoral head that compressed the femoral vessels. We diagnosed this bone mass as a capital drop secondary to hip OA after confirming that the mass occurred at least after the age of 63 years based on a previous X-ray. We performed early resection and total hip arthroplasty since the patient's hip pain was due to both advanced hip OA and compression of the femoral vessels; moreover, we aimed to prevent venous thrombosis secondary to vascular compression considering the advanced age and the potent risk of thrombosis in the patient. A large capital drop should be considered as a cause of vascular compression in cases of unilateral leg edema in OA patients.

Cystic lesion around the hip joint

This article presents a narrative review of cystic lesions around the hip and primarily consists of 5 sections: Radiological examination, prevalence, pathogenesis, symptoms, and treatment. Cystic lesions around the hip are usually asymptomatic but may be observed incidentally on imaging examinations, such as computed tomography and magnetic resonance imaging. Some cysts may enlarge because of various pathological factors, such as trauma, osteoarthritis, rheumatoid arthritis, or total hip arthroplasty (THA), and may become symptomatic because of compression of surrounding structures, including the femoral, obturator, or sciatic nerves, external iliac or common femoral artery, femoral or external iliac vein, sigmoid colon, cecum, small bowel, ureters, and bladder. Treatment for symptomatic cystic lesions around the hip joint includes rest, nonsteroidal anti-inflammatory drug administration, needle aspiration, and surgical excision. Furthermore, when these cysts are associated with osteoarthritis, rheumatoid arthritis, and THA, primary or revision THA surgery will be necessary concurrent with cyst excision. Knowledge of the characteristic clinical appearance of cystic masses around the hip will be useful for determining specific diagnoses and treatments.

Femoral vein compression resulting from a ganglion of the hip joint: a case report

The development of a ganglion in the hip joint is a rare cause of lower limb swelling. We herein describe a case of a ganglion of the hip with compression of the femoral vein that produced signs and symptoms that mimicked a deep vein thrombosis. Needle aspiration of the ganglion was easily performed, and swelling of the left lower limb promptly improved. Intensive follow-up of this case was important because the recurrence rate of ganglions after needle aspiration is high.
