We report a case of pathological splenic rupture as a manifestation of malignant metastatic spindle cell tumour. To the best of our knowledge, this is the first case report of an atraumatic-pathological rupture of the spleen secondary to metastatic malignant spindle cell tumour. A 63-year-old man with a previous history of right upper limb amputation for an axillary malignant spindle cell tumour was admitted with an acute abdomen. Computed tomography showed a ruptured spleen. The patient subsequently underwent splenectomy. Histopathology confirmed the presence of malignant metastatic spindle cell tumour. Pathological splenic rupture is a rare manifestation of metastatic malignant spindle cell tumour. Background oncological history and thorough examination of the musculoskeletal system may provide important clues to make a prompt diagnosis.

OBJECTIVETo investigate the correlation between the stage of hepatic fibrosis and ultrasonographic findings of the liver, spleen and gallbladder and establish a sensitive ultrasonographic semi-quantitative scoring system for screening compensated liver cirrhosis.

METHODSTotalling 248 patients with chronic hepatitis B and hepatitis C virus infection underwent liver biopsy and ultrasonic examination. The images of the liver surface, parenchymal echo, intrahepatic vessels, gallbladder, spleen and diameter of portal vein were analyzed.

RESULTSThe stages of hepatic fibrosis were not correlated to ultrasonographic findings of the liver surface or diameter of portal vein, but hepatic fibrosis of different stages showed significant differences in parenchymal echo, intrahepatic vessels, gallbladder and splenomegaly. In cases with normal liver parenchymal, intrahepatic vessels, gallbladder and spleen, the negative predictive value of the ultrasonographic semi-quantitative scoring system for diagnosing compensated liver cirrhosis amounted to 96.3%. The sensitivity of a score not lower than 5 was 90% for detecting compensated cirrhosis. With a score not lower than 7, the diagnostic accuracy and specificity was 85.9% and 95.2%, respectively, but the sensitivity was lowered to 37.5%.

CONCLUSIONThe ultrasonic images of the liver parenchyma, intrahepatic vessels, gallbladder and spleen in patients with compensated liver cirrhosis vary significantly in patients with hepatic fibrosis of different stages, and this ultrasonographic scoring system allows for a sensitive diagnosis of compensated cirrhosis.

Most cases of accessory spleen show similar features as normal spleen in imaging studies. However, some accessory spleen has unusual scan feature which can be misdiagnosed. We present a case of intrapancreatic accessory spleen that was discovered incidentally during a workup for abdominal pain in a 47-year-old woman. CT and MRI revealed a different enhancing pattern from that of the spleen. Further evaluation with endoscopic ultrasonography failed to identify the pancreatic mass. Therefore, it was surgically removed and diagnosed pathologically as an accessory spleen.

We report a case of a 61-year-old man who presented with a cough and abdominal discomfort. CT scan of the chest showed two lesions across both lungs, and an abdominal CT scan revealed multiple hypodense lesions in the spleen with cystic lesions on the splenic hilum. Upper gastrointestinal tract endoscopy found creamy yellowish discharge through a fistula between the stomach and splenic hilum. Under fluoroscopic guidance, forceps was inserted into the fistula tract, and forcep biopsy was done. The pathology was consistent with tuberculosis, and a nine-month anti-tuberculosis medication regimen was started. Imaging performed three months after finishing medication indicated improvement of splenic lesions, and the gastro-splenic tract was sealed off. This case is a very rare clinical example of secondary splenic tuberculosis with a gastro-splenic fistula formation in an immunocompetent patient.

OBJECTIVE: To conduct signature analysis for splenic trauma in canines during hemorrhagic shock and resuscitation by contrast enhanced ultrasonography (CEUS). METHODS: Forty grade III-IV traumatic splenic lesions were established in 15 mongrel dogs. Hemorrhagic shock was induced in these animals by using the modified Wiggers's method. Animals in shock were then resuscitated with 6% hydroxyethyl starch. The features of splenic trauma during hemorrhagic shock or resuscitation were assessed by CEUS, which were compared with the data collected by contrast-enhanced computed tomography (CECT). Acoustic quantification of CEUS was performed to assess splenic blood perfusion in different stages. RESULTS: There was no significant difference in detection rate between CEUS and CECT during hemorrhagic shock and resuscitation. Before hemorrhagic shock, there were 40 traumatic bleeding lesions and 85% of them were revealed by CEUS (34/40). With the progress in shock, CEUS revealed that the numbers of tiny branches of splenic arteries were decreased, which became thinner with no active bleeding. After fluid resuscitation, rebleeding was occurred in 30 traumatic lesions, and 28 (93.3%) of them were captured by CEUS. CEUS could also visualize the changes in splenic perfusion in different stages. During the shock, the arrival time (AT), time to peak intensity (TTP), peak intensity (PI) were significantly lower and the washout time (WT) were significantly higher than those at other stages (P<0.01). CONCLUSION CEUS not only can dynamically monitor the changes in spleen traumatic hemorrhage and recurrent hemorrhage, but also can quantitatively study the changes in spleen blood perfusion in different stages.

OBJECTIVETo assess the feasibility and safety of radiofrequency ablation (RFA) in spleen to treat secondary splenomegaly and hypersplenism in dogs.

METHODSFourteen healthy mongrel dogs were randomly divided into two groups: group A (n = 4) and group B (n = 10) Both groups underwent ligation of the splenic vein and its collateral branches to induce congestive splenomegaly. At the end of the 3rd week, radiofrequency thermal ablation of the spleen was performed in the group B via laparotomy. After splenic RFA, the procedure-related complications were observed, CT scan was performed and the spleens were obtained according to schedule. The radiofrequency (RF) thermal lesions and its histo- pathological changes of the spleen were examined regularly.

RESULTSThere were no morbidity and mortality in the experimental dogs. CT findings revealed that splenomegaly could sustained over 2 months after ligation of the splenic vein. The segmental RF lesions included hyperintense zone of coagulative necrosis and more extensively peripheral hypo-intense infarcted zone. The latter was called as "bystander effect". The infarcted zone would be absorbed and subsequently disappeared between 4 and 6 weeks after RFA, and the size of the remnant spleen shrunk, but the lesion of coagulative necrosis hardly altered. The fundamental histopathological changes of splenic lesions caused by RF thermal energy included local coagulative necrosis and the peripheral thrombotic infarction zone. Subsequently, tissue absorption and fibrosis occurred in the zone of thrombotic infarction. Simultaneously occluded vessels, fibrin deposition, and disappearance of normal splenic sinuses resulted in the condensed structure of the viable remnant spleen, which were the pathological basis responsible for the shrunk spleen.

CONCLUSIONSIt is feasible and safe to perform RFA in the spleen to treat experimental splenomegaly and hypersplenism. The RFA technique could be safely performed clinically via laparotomy or laparoscopic procedure to strictly isolate the spleen from the surrounding organs.
