AbstractCerebrospinal fluid (CSF) peritoneal pseudocysts are a rare complication of ventriculoperitoneal shunts. They can manifest with symptoms of shunt malfunction or, more commonly, vague symptoms of abdominal discomfort such as pain or distention. The imaging features of peritoneal CSF pseudocysts may be nonspecific. In this case, we report a peritoneal CSF pseudocyst, which was initially mistaken for a complex hepatic cyst on both ultrasonography and MRI. The correct diagnosis was confirmed with a shuntogram and CT of the abdomen.

Underlying Mechanisms

Background: Ventriculoperitoneal shunts (VPSs) insertion is the most common used intervention in cases of hydrocephalus. The main postoperative complications are infections and catheter obstructions. Although the literature has well-documented cases describing migration of the distal catheter, this rare presentation can become more confusing when occurring in conjunction with some unusual preexistent morbidity in the patient, as a Grynfeltt hernia. Case Description: This study reports a rare case of a VPS postoperative migration, in which the distal catheter exits the abdominal cavity through a Grynfeltt hernia. This condition was not discovered until the catheter fistulated through the overlying skin. The Grynfeltt hernia is the most uncommon among the lumbar ones and it’s asymptomatic in the majority of the cases, being hardly diagnosed. Conclusion: The unusualness of the reported case deserves furthermore discussion to properly evaluate these underlying mechanisms of catheter migration.

Occluding Balloon

Acquired renal arteriovenous fistula is a rare complication following a nephrectomy and its diagnosis may be made many years after the intervention. The closure of the fistula is advisable in most cases, since it represents a risk for heart failure and rupture of the vessel. There are an increasing number of publications describing different techniques of occlusion. The case of a 70-year-old woman with abdominal discomfort due to a large renal arteriovenous fistula, 45 years after nephrectomy, is presented and current literature is reviewed. Percutaneous embolization was performed by placing an occluding balloon through the draining vein followed by the release of nine coils through arterial access. One day after successful occlusion of the fistula, clinical symptoms disappeared.

Tuberculous prostatitis is an uncommon form of tuberculosis infection. It is commonly seen in immunocompromised patients and in those of middle or advanced age. The diagnosis is often not straight forward due to the nature of its presentation. We report a case of tuberculous prostatitis in a young, healthy and immunocompetent patient, who initially presented with respiratory features, followed by episodes of seizures and testicular swelling. He was finally diagnosed with tuberculous prostatitis after prostatic biopsy. This case illustrates that in a high TB prevalence environment, when symptoms warrant, there should be a high clinical suspicion coupled with a thorough approach in order to arrive at a correct diagnosis of TB prostatitis.

Mesenchymal Tumours

<P>Background: Primary Hepatic Epithelioid Haemangioendothelioma (HEHE) and Primary Hepatic Angiosarcoma (PHA) are rare mesenchymal tumours with different malignant potential. Whereas HEHE demonstrates low to intermediate malignant potential, PHA is an aggressive malignancy with poor prognosis. The knowledge of typical imaging features of these lesions may facilitate correct diagnosis; however, the ultimate diagnosis of HEHE and PHA is based on histopathologic examination. </P><P> Discussion: The most typical findings helpful in diagnosing HEHE are: Presence of multiple, confluent nodules located at the liver periphery (in young to middle-aged woman), retraction of the liver capsule, marked hyperintensity on T2-weighted images, “target-sign” appearance, progressive centripetal contrast enhancement, and relatively high Apparent Diffusion Coefficient (ADC) values. More than &#8805;50% of nodules are hyper- or isointense on Hepatobiliary Phase (HBP) images. Conclusion: The imaging features suggestive of PHA are: Occurrence of metastases (lungs, spleen) at the time of diagnosis, presence of a large dominant mass with smaller satellites, heterogeneity and areas of haemorrhage in a dominant mass, progressive contrast enhancement, slightly elevated ADC values as compared to other malignant liver tumours.</P>

<b><i>Introduction:</i></b> Epidural blood patches (EBPs) are rarely performed at the high-level cervical levels. The aim of the study was to investigate the imaging features, safety, and effectiveness of CT-guided percutaneous EBPs for high-level cervical cerebrospinal fluid (CSF) leakage. <b><i>Methods:</i></b> Twenty-five patients with spontaneous high-level (C1–C3) CSF leakage on MRI and CT imaging, including 2 patients with intracranial epidural hematoma caused by CSF, were treated with EBP. Two needles were inserted into the C1–3 bilateral epidural space. The needle location was confirmed by injection of both 3–5mL sterile air and a diluted iodinated contrast agent to delineate its spatial diffusion. The patient’s blood 11.1 ± 3.1 mL was slowly injected to make a patch; the distribution in epidural space was monitored with intermittent CT scanning. <b><i>Results:</i></b> The typical manifestation of CSF leakage was the high signal outside the C1–3 cervical dura on MR T2W fat inhibition images and low density in cervical muscle space on CT images. Twenty patients suffered from headaches and were able to sit and walk 24 h after the operation. Four patients, with partial relief of headache and a small but persistent CSF leakage, were re-treated with EBS. One patient underwent a third operation because of a persistent CSF leakage on MRI. <b><i>Conclusions:</i></b> Imaging of water at the surrounding epidural space of high cervical level is a typical feature of dural rupture on both MRI and CT. CT-guided EBP is safe and efficient for the high-level cervical CSF leakage, especially for cases in which conservative treatments failed.

Leptomeningeal metastasis (LM) is a fatal and rare complication of cancer in which the cancer spreads via the cerebrospinal fluid (CSF). At present, there is no definitive treatment or diagnosis for this deleterious disease. In this study, we systemically and quantitatively investigated biased expression of key small non-coding RNA (smRNA) subpopulations from LM CSF extracellular vesicles (EVs) via a unique smRNA sequencing method. The analyzed subpopulations included microRNA (miRNA), Piwi-interacting RNA (piRNA), Y RNA, small nuclear RNA (snRNA), small nucleolar RNAs (snoRNA), vault RNA (vtRNA), novel miRNA, etc. Here, among identified miRNAs, miR-21, which was already known to play an essential oncogenic role in tumorigenesis, was thoroughly investigated via systemic biochemical, miR-21 sensor, and physiological cell-based approaches, with the goal of confirming its functionality and potential as a biomarker for the pathogenesis and diagnosis of LM. We herein uncovered LM CSF extravesicular smRNAs that may be associated with LM-related complications and elucidated plausible pathways that may mechanistically contribute to LM progression. In sum, the analyzed smRNA subpopulations will be useful as targets for the development of therapeutic and diagnostic strategies for LM and LM-related complications.

Pseudocyst Formation

Despite its numerous benefits, peritoneal dialysis (PD) can rarely result in dangerous and even life-threatening complications, including peritonitis, hernias, encapsulating peritoneal sclerosis (EPS), and rarely peritoneal pseudocysts. Herein, we present a rare case of a giant intra-peritoneal pseudocyst that presented four months following the discontinuation of a 5-year course of complicated PD. Despite the initially successful drainages, the patient’s symptoms continued to recur, and the imaging findings were concerning for underlying neoplastic processes. As such, a staged surgical approach was performed, starting with a diagnostic laparoscopy and was subsequently followed with cyst excision and marsupialization to the peritoneal cavity. While previous reports of such rare pseudocyst have been documented in the literature as a complication of PD, to our knowledge, this is the second case of pseudocyst formation to occur months after the discontinuation of PD therapy. This case emphasizes the importance of close follow-up in PD patients and showcases how a staged surgical approach can be utilized to accurately diagnose and manage such complicated cases.
