Rare Diagnosis

Primary diaphragmatic cyst – is a very rare diagnosis with complicated determination due to its specific anatomical location and close relation to other organs[1, 3]. However, diaphragmatic cysts are commonly discovered accidentally while performing visual examination because of totally other reasons [4]. 7-year-old male patient presented with abdominal pain and abdominal ultrasonography was performed. There was accidentally found a hepatic cyst of 39 × 30 mm size in right lobe of the liver. Operation was planned because of the cystic lesion enlargement. During the operation diaphragmatic cyst was found. Pathological examination revealed that this lesion is a mesothelial cyst of peritoneum.

Foregut Cyst

Background. Gallbladder ciliated foregut cysts (CFCs) of the lower diaphragm are extremely rare. Furthermore, they are rarely suspected of malignancy preoperatively. Case Presentation. A 50-year-old woman was referred to our hospital for further examination and treatment of a gallbladder tumor that was detected using abdominal ultrasonography (US). After a close inspection, she was diagnosed with a gallbladder tumor that was possibly malignant. Accordingly, open whole layer cholecystectomy was performed because intraoperative US revealed a tumor located on the intraperitoneal side of the gallbladder, and a rapid intraoperative pathological diagnosis identified no malignancy. A postoperative pathological examination revealed a cystic lesion with thin walls covered with ciliated epithelium, which laid on a connective tissue with smooth muscle fibers. Based on the above results, the final pathological diagnosis was CFC of the gallbladder without malignancy. Conclusions. Cases of gallbladder CFC can be considered as cysts requiring treatment owing to CFCs’ potential for malignant transformation and high-frequency symptoms.

Cystic echinococcosis (CE) is a rare afferent infectious disease in Japan. This paper reports a case of a hepatic cyst being diagnosed after surgical resection. A 40-year-old Syrian male was admitted for evaluation of a hepatic cyst. Serum antibodies of echinococcosis were negative. Enhanced computed tomography of the abdomen revealed a large cystic lesion, 9 cm in diameter, in the left lateral sector of the liver, which had many honeycomb-like septa and calcified lesions. Magnetic resonance imaging of this lesion revealed high intensity in the T2 weighted image. We preoperatively diagnosed this lesion as cystadenocarcinoma or CE and performed a left hepatectomy. Pathological examination revealed the presence of protoscolices in the fluid of the cysts and led to a diagnosis of this lesion as CE. In conclusion, on seeing patients with huge hepatic cysts who come from an epidemic area, we should consider hepatic CE.

A 60-year-old woman was investigated for abdominal pain and increasing asthenia. Abdominal CT revealed a 25 mm hypodense cystic lesion in the tail of the pancreas. MRI showed a multiloculated cystic lesion, T1-hypointense and T2-hyperintense lesion, without wall enhancement. Endoscopic ultrasound detected a 25 mm multi-loculated cystic lesion, with regular margin and without pancreatic duct communication. Diagnosis of pancreatic mucinous cystadenoma was discussed and the patient was referred to surgery. She underwent distal pancreatectomy with spleen preservation. Pathological examination revealed the diagnosis of pancreatic mesothelial cyst. Histologically, the cyst was multiloculated, lined by cuboidal epithelium, ovoid nuclei and amphophilic cytoplasm, without mucin deposition or cytological atypia. Immunohistochemistry examination revealed positive staining for cytokeratin 5/6, vimentin and calretinin. At 1-year follow-up, she is in her usual health, without any symptoms.

Simple Hepatic Cyst

Background and Aims Simple liver cyst (SHC) is a benign condition with no malignant potential. They are typically discovered incidentally due to the increased use of abdominal imaging, but some patients may present with abdominal pain. A radiologist’s differential diagnosis in cases of SHC will often include “rule out biliary cystadenoma.” Under these circumstances, patients and surgeons are more likely to pursue surgical options even in asymptomatic cases. The aim of this study is to conduct a retrospective analysis of presentation, radiologic reporting, management plan, and histopathology of patients referred to a tertiary hospital in order to determine the correlation between radiology and histology. Methods We retrospectively analyzed the clinical, radiological, and histopathological data of 20 patients operated for a diagnosis of a cystic lesion in the liver. Result The CT/MRI of 6 (30%) patients was reported as a biliary cystadenoma, 13 (65%) were reported as a simple hepatic cyst and 1 patient (5%) had hepatocellular carcinoma (HCC) with the additional diagnosis of multiple hepatic cysts. The lesion reported as HCC on the scan was separate from the cystic lesions. The modality of imaging for these cysts was evenly split, 50% of patients had a CT scan, and 50% had an MRI performed. All imaging studies were interpreted by an attending radiologist and most of them were discussed in multidisciplinary meetings. Nineteen patients (95%) had an intraoperative diagnosis of a simple liver cyst based on its visual appearance and clear fluid within the cyst. These patients underwent cyst wall fenestration and de-roofing with the cyst wall sent for histopathology. One patient (5%) with HCC underwent a non-anatomical liver resection. Histopathology was conclusive for a benign hepatic cystic lesion from the cyst wall biopsy. All 20 patients in this study underwent surgery, either due to symptoms or due to radiologic diagnosis of BCA. Four of the 20 cases (20%) were asymptomatic and out of these four cases, 3 (75%) were diagnosed as cystadenoma on the preoperative imaging studies. All 19 cases were diagnosed as a simple liver cyst on pathology. Conclusion In summary, there is a growing trend of “ruling-out the diagnosis of biliary cystadenoma” in patients who present with liver cysts. Patients are appropriately more anxious after this preoperative diagnosis and the treating surgeons have medico-legal concerns regarding conservative management in asymptomatic patients diagnosed as BCA. This single center experience draws attention to the radiology criteria utilized for diagnosing a biliary cystadenoma and suggests that it is time to revisit the imaging interpretation and differential diagnosis.

Rationale and Objectives. To investigate the utility of intravoxel incoherent motion MRI (IVIM-MRI) and R2⁎ mapping in diagnosing early stage liver fibrosis in a radiation-induced rat model. Materials and Methods. Thirty rats were randomly divided into three groups with 10 rats in each group. Liver fibrosis was induced by exposure of right lobe of liver in each animal to 20 Gy of radiation. MRI examination was conducted at baseline, one month, two months, and three months after radiation using T1WI, T2WI, IVIM-DWI, and R2⁎ sequences. The pathological examination included hematoxylin eosin, masson trichrome, and prussian blue staining. D, D⁎, f, and R2⁎ values were measured in both left and right lobes for quantitative analysis. Results. Regarding the surviving 23 rats, eight rats were diagnosed with stage F0, ten with stage F1, and five with stage F2 liver fibrosis using METAVIR Scores. The D values of right lobes decreased (P<0.05), and R2⁎ values increased (P<0.01) significantly as fibrosis levels increased. But there was no statistical difference in D⁎ (P=0.970) and f values (P=0.079). R2⁎ value showed a strong positive correlation (r=0.819, P<0.001), while D value showed a negative correlation with fibrosis stages (r=-0.424, P<0.001). D⁎ (r=0.029, P=0.744) and f values (r=-0.055, P=0.536) were poorly correlated with fibrosis levels. Conclusion. IVIM-MRI and R2⁎ mapping are useful techniques for evaluating the severity of liver fibrosis in a radiation-induced rat model, and R2⁎ value is the most sensitive parameter in detecting early stage fibrosis.

Abstract Lymphatic type of adrenal cysts is most common; however, this type of endothelial cyst is quite rare in excessively large adrenal cysts. A 37-year-old Japanese woman was admitted to our institution with distension of her left flank and the upper quadrant of her abdomen. Abdominal ultrasonography revealed a cystic lesion with a homogenous anechoic texture, and measuring 21 cm in diameter. Computed tomography and magnetic resonance imaging displayed a giant cystic lesion adjacent to the liver, pancreas, kidney, and spleen. The origin of the cyst was not identified. We were not able to make a preoperative diagnosis; therefore, the patient underwent resection of the mass by open laparotomy for therapeutic diagnosis. Intraoperatively, the mass was identified to be cystic and adhered to the left adrenal gland. It was filled with more than 2000 mL of serous brown-red fluid. The content of the cyst contained no atypical cells on cytological examination. The wall of the cyst was composed of a lining of a single layer of lymphatic vessel–derived cells, and the cyst was pathologically classified as a true cyst. No abdominal symptoms were observed and a postoperative radiological work-up showed no evidence of recurrence during a 6-year follow-up period. We describe a case of a patient with a giant lymphatic cyst of the adrenal gland. The preset data suggest that surgeons should decide treatment strategy for large adrenal cysts in consideration of hormonal function, degree of size, and possibility of malignancy.

Rare Diagnosis

Introduction. Agenesis of the right lobe of the liver is a rare finding and was defined as the absence of liver tissue on the right side, with preservation of the middle hepatic vein, without previous disease or surgery. It is usually an incident finding reveled by imaging exams or during abdominal surgery.Case Report. A 32-year-old male patient was admitted to the hospital for abdominal discomfort and loss of appetite. Imaging studies revealed the absence of the right hepatic lobe and hypertrophied left hepatic segments.Discussion. Anomalies of hepatic morphology are rare and correspond to developmental defects during embryogenesis, are a rare diagnosis, and are generally diagnosed incidentally based on imaging. Agenesis or hypoplasia of the right lobe may predispose the patient to the development of portal hypertension and esophageal varices. Surgical knowledge of such anatomical agenesis is necessary for surgical planning, for the appropriate identification of intraoperative surgical findings, and for the design of the postoperative approach to therapy.Conclusion. Agenesis of the right hepatic lobe is a rare condition. We want to highlight the importance of understanding the condition. Surgeons must recognize the entity in order to deal appropriately with the findings.

✓ This case report contains a description of a 61-year-old patient who presented with a progressive truncal ataxia 22 years after complete removal of a small paraganglioma of the cauda equina. Magnetic resonance imaging of the neuraxis revealed a large cystic lesion in the cerebellar midline, three small cortical-to-subcortical nodular tumors in the posterior fossa, and local recurrences of the paraganglioma of the cauda equina. Pathological examination showed the cerebellar midline lesion to be a paraganglioma, most likely a metastasis from the cauda equina localization.
