Abdominal Pseudocyst

Abstract Background Abdominal cerebrospinal fluid (CSF) pseudocyst is an uncommon but important complication of ventriculoperitoneal (VP) shunts. While individual articles have reported many cases of abdominal CSF pseudocyst following VP shunts, no case of a hemorrhagic abdominal pseudocyst after VP shunts has been reported so far. Case presentation This article reports a 68-year-old woman with a 4-month history of progressive abdominal pain and distention. She denied any additional symptoms. A VP shunt was performed 15 years earlier to treat idiopathic normal pressure hydrocephalus and no other abdominal surgery was performed. Physical examination revealed an elastic palpable mass in her right lower abdomen, which was dull to percussion. Abdominal computed tomography (CT) scan indicated a large cystic collection of homogenous iso-density fluid in the right lower abdominal region with clear margins. The distal segment of the peritoneal shunt catheter was located within the cystic mass. Abdominal CSF pseudocyst was highly suspected as a diagnosis. Laparoscopic cyst drainage with removal of the whole cystic mass was performed, 15-cm cyst which found with thick walls and organized chronic hematic content. No responsible vessel for the cyst hemorrhage was identified. No further shunt revision was placed. Histological examination showed that the cyst wall consisted of outer fibrous tissue and inner granulation tissue without epithelial lining, and the cystic content was chronic hematoma. The patient had an uneventful postoperative course and remained asymptomatic for 8-mo follow-up. Conclusion To the best of our knowledge, this is the first report of hemorrhagic onset in the abdominal pseudocyst following VP shunt. Such special condition can accelerate the appearance of clinical signs of the abdominal pseudocyst after VP shunts, and its mechanisms may be similar to the evolution of subdural effusion into chronic subdural hematoma (CSDH).

Comparative Review

SummaryCases of cystic bone lesions in horses and humans were reviewed in the literature. These lesions are radiolucent areas of bone, recognized as subchondral cystic lesions in the horse (SCL), intra-osseous ganglia (IOG), subchondral bone cysts secondary to osteoarthrosis (OAC), and unicameral bone cysts (UCB) in humans. Their morphology is quite similar, consisting of lesions with a distinct cyst wall, and a cavity filled with fibrous tissue and yellowish mucoid fluid. The lesions are surrounded by sclerotic bone and can be easily diagnosed radiographically. SCL, IOG and OAC occur in the subchondral bone close to the adjacent joint, whereas UCB occur in the metaphysis of long bones. Their aetiology and pathogenesis is still unknown, although primary damage to the subchondral bone, cartilage or local blood supply and growth disturbances are discussed. In this review 703 lesions of SCL in horses, 289 lesions of IOG and 1460 lesions of UCB in humans were compared in their anatomical location and clinical signs. SCL and OAC resembled each other with respect to anatomical location. A correlation of affected bones could not be found for all four groups. Clinical presentation concerning age was most similar for SCL and UCB with both lesions mainly occurring in young individuals. Gender predominance of males was present in SCL, IOG and UCB. Clinical diagnosis was either incidental, or connected with intermittent pain in all lesions except for OAC. Additionally, the lesions were also found in conjunction with degenerative joint disease (SCL, OAC) or pathological fractures (UCB). Cystic bone lesions were either treated conservatively, surgically with curettage alone, curettage in combination with grafting procedures, or intra-lesional application of corticosteroids. SCL and UCB were similar in their biological behaviour concerning their slow response to the therapy and relatively high recurrence rate. None of the cystic bone lesions were comparable, and a common aetiology and pathogenesis could not be found.In a literature review cases of cystic bone lesions in horses and humans were compared with the goal to find a common aetiology and pathogenesis. Cystic bone lesions occur in horses as subchondral cystic lesions (SCL), and in humans as either intra-osseous ganglia (IOG), subchondral cystic lesions secondary to osteoarthrosis (OAC) or unicameral bone cysts (UCB). IOG and OAC compare with SCL mainly in the anatomical location. IOG and SCL resemble each other in size, clinical signs and histology, whereas UCB and SCL show a similar biological behaviour regarding their therapeutic response and recurrence rate. None of the cystic bone lesions in humans were comparable to the SCL in horses in all aspects. A common aetiology and pathogenesis could not be established.

Associated Symptoms

A complication of ventriculoperitoneal (VP) shunting is overdrainage or overshunting of cerebrospinal fluid, which can cause formation of hygroma but in rare cases also cervical myelopathy at a later stage. In this article, we describe a very late complication of VP shunting. We present a 75-year-old man, previously given a VP shunt at the age of 46, who developed a progressive gait disturbance and ataxia of the limbs after 27 years. MRI showed a cervical stenosis and myelopathy as a result of venous engorgement due to chronic overshunting of the VP shunt. Revision of the VP shunt resulted in complete resolution of his neurological symptoms and the cervical myelopathy. Cervical myelopathy due to chronic overshunting is a rare and potentially very late complication of a VP shunt. Our case underlines the importance of awareness of this complication while proper treatment can reverse the associated symptoms fully.

✓The authors describe the case of a 36-year-old woman with bilateral internal jugular vein occlusion, hydrocephalus, and Dandy–Walker variant who presented with myelopathy that was ultimately attributed to ventriculoperitoneal (VP) shunt failure. Computed tomography (CT) angiography of the head and neck revealed epidural venous engorgement within the cervical spine, greater that 50% narrowing of the C2–5 spinal canal, and compression of the cervical spinal cord. After successful shunt revision, postoperative CT angiography revealed decreased venous engorgement as well as decompression of the cervical spinal cord, and the patient’s myelopathy improved. This case represents a fascinating clinical presentation of VP shunt failure, highlighting the physiological importance of the external jugular pathways involved in cerebral venous drainage.

Abstract Background Cerebrospinal fluid (CSF) abdominal pseudocyst (APC) is an uncommon complication following ventriculoperitoneal (VP) shunt. Aim To study the clinical features and management of this entity. The authors present their experience with cases of CSF pseudocyst in children. Materials and Methods Retrospective analysis of four cases diagnosed to have APC following VP shunt between 2005 and 2015. Results Clinical presentation was with progressive abdominal distension, highlights of intestinal obstruction, and signs of raised intracranial pressure (ICP). Diagnosis is readily made with ultrasonography and computed tomographic (CT) scan of the abdomen. The duration between insertion of the shunt and the presentation ranged from 4.11 to 12 years. In three patients, the cyst was unilocular and of varying size. The fourth one had a multilocular cyst. In three patients, the treatment involved was surgical removal of the catheter with excision of the pseudocyst wall and placement of a new catheter intraperitoneally in a different quadrant. Ultrasound-guided aspiration of the cyst and relocation of the distal end was done in one patient. Conclusion Initial suspicion with appropriate investigation and early treatment can avert morbidity and mortality.

OBJECTIVE Children whose ventricles do not change during shunt malfunction present a diagnostic dilemma. This study was performed to identify risk factors for unchanged ventricular size at shunt malfunction. METHODS This retrospective 1:1 age-matched case-control study identified children with shunted hydrocephalus who underwent shunt revision with intraoperative evidence of malfunction at one of the three participating institutions from 1997 to 2019. Cases were defined as patients with a change of < 0.05 in the frontal–occipital horn ratio (FOR) between malfunction and baseline, and controls included patients with FOR changes ≥ 0.05. The presence of infection, abdominal pseudocyst, pseudomeningocele, or wound drainage and lack of baseline cranial imaging at the time of malfunction warranted exclusion. RESULTS Of 450 included patients, 60% were male, 73% were Caucasian, and 67% had an occipital shunt. The median age was 4.3 (IQR 0.97–9.21) years at malfunction. On univariable analysis, unchanged ventricles at malfunction were associated with a frontal shunt (41% vs 28%, p < 0.001), programmable valve (17% vs 9%, p = 0.011), nonsiphoning shunt (85% vs 66%, p < 0.001), larger baseline FOR (0.44 ± 0.12 vs 0.38 ± 0.11, p < 0.001), no prior shunt infection (87% vs 76%, p = 0.003), and no prior shunt revisions (68% vs 52%, p < 0.001). On multivariable analysis with collinear variables removed, patients with a frontal shunt (OR 1.67, 95% CI 1.08–2.70, p = 0.037), programmable valve (OR 2.63, 95% CI 1.32–5.26, p = 0.007), nonsiphoning shunt at malfunction (OR 2.76, 95% CI 1.63–4.67, p < 0.001), larger baseline FOR (OR 3.13, 95% CI 2.21–4.43, p < 0.001), and no prior shunt infection (OR 2.34, 95% CI 1.27–4.30, p = 0.007) were more likely to have unchanged ventricles at malfunction. CONCLUSIONS In a multicenter cohort of children with shunt malfunction, those with a frontal shunt, programmable valve, nonsiphoning shunt, baseline large ventricles, and no prior shunt infection were more likely than others to have unchanged ventricles at shunt failure.

CONTEXT: VP Shunt is most commonly used procedure for hydrocephalus but shunt failure is also the common complication in many patients. Endoscopic third ventriculostomy (ETV) is an accepted procedure for the treatment of obstructive hydrocephalus. The aim of our study is to evaluate the success rate AIM AND OBJECTIVE - of ETV in patients of obstructive hydrocephalus formerly treated by ventriculo-peritoneal (VP shunt) shunt. The failure VP shunt was removed before ETV. MATERIALS AND METHOD: This study was conducted between June 2015 and December 2019 in single unit of our department. Twenty one (n=21) patients were enrolled for this study. All patients were admitted with failure of VP shunt. They were known case of non-communicating hydrocephalus previously operated for VP shunt. Six patients were excluded for ETV because CT/MRI show grossly distorted anatomy of ventricles. Endoscopic third ventriculostomy was attempted in 15 patients, but ventriculostomy was done successfully in 10 patients, rests were treated with revision of VP shunt. All patients in this study were radiologically diagnosed RESULTS: case of hydrocephalus due to aqueduct stenosis. They were experienced VP shunt insertion but there were failure of shunt due to any reason. ETV procedures were done successfully in 10 patients. Out of 10 patients one patient needed shunt insertion due ineffective ETV. Shunt revision was done in 11 patients. There was no serious complication during and after ETV procedures. The follow-up period of patients with successful ETV was 6–60 months. This follow-up was uneventful and peaceful for their parents. ETV can be considered as an alternative treatment for the patients w CONCLUSION: ith VP shunt failure with an acceptable success rate of 80%, although long-term follow-up is needed for these patients.

An 89-year-old man with a history of multiple abdominal surgeries and ventriculoperitoneal (VP) shunt placement for normal pressure hydrocephalus presented for intractable abdominal bloating and scrotal swelling, for which imaging revealed massive ascites, bilateral hydrocele and small bilateral pleural effusions. Cardiac, hepatic and renal workup were insignificant. Culture and cytology of ascitic fluid were negative for infection or malignancy. Aetiology of the ascites as secondary to Cerebrospinal fluid (CSF) from the VP shunt was confirmed via ligation of the shunt. Sterile CSF ascites, hydrothorax and hydrocele are rare complications of VP shunt for hydrocephalus and are mostly presented in paediatric patients. We report the first known case of concurrent CSF ascites, hydrothorax and hydrocele in an elderly patient. We examine the difficulty of shunt replacement as a diagnostic and treatment modality in this age group and propose the use of reversible shunt ligation as a diagnostic modality.

Abstract Objectives We present a patient with a prolactin-secreting adenoma with extensive secondary, noninfectious, xanthogranulomatous changes due to remote intratumoral bleeding and provide a literature review of xanthogranulomas (XGs) of the sellar region with emphasis on prolactinomas with xanthogranulomatous features. Design Case report, with PubMed search of cases of sellar XG, focusing on neuroimaging and surgical approach. Results A 35-year-old male was found to have a large sellar/suprasellar calcified/cystic mass. Endoscopic transsphenoidal approach for extradural resection was performed and diagnosis made. Review generated 31 patients with the diagnosis of sellar XG. In a minority (6 patients), the underlying lesion for the XG was a pituitary adenoma. Headache was the most common presenting symptom and panhypopituitarism the most common endocrinological abnormality. Examples of hyperprolactinemia associated with sellar XG are also uncommon and due to stalk effect. Neuroimaging of XG on T1-weighted magnetic resonance imaging (MRIs) showed 18 cases (56.3%) were hyperintense, 1 case (3.13%) was isointense, 4 (12.5%) had mixed-signal intensity, and 2 (6.25%) were hypointense. On T2-weighted MRIs, five lesions (15.6%) were hyperintense, three (9.38%) were isointense, nine (28.1%) were heterogeneous, and nine (28.1%) were hypointense. Only one case (3.1%) had calcifications on computed tomography scan similar to ours. In 14 cases (43.7%), the lesions enhanced with contrast administration on MRI. Conclusion Prolactinomas with secondary xanthogranulomatous change represent a rare cause of XG of the sella. With no radiological or clinical signs specific for XG of the sellar region, preoperative diagnosis can be challenging, if not impossible.
