RESUMEN
ABSTRACT: Splenic abscess is a life-threatening condition, which is very rare in children. There is usually an infective focus or pre-disposing factors such as immunodeficiencies towards developing splenic abscesses. Only one case of splenic abscess with brain abscesses in an adult has been reported in the English literature. We, therefore, report a case of an 11-year-old boy who was otherwise healthy, but presented with fever and weight loss for 2 months, right upper abdominal pain, vomiting, hypochondrial tenderness for 1 week and later on developed a left hemiplegia and right facioparesis 2 days before presentation. Diagnosis of splenic abscess and right intracerebral abscesses was confirmed with abdominopelvic ultrasound scan and abdominal and cranial computerised tomographic scans. He subsequently had percutaneous ultrasound-guided drainage of the splenic abscess which was not successful necessitating splenectomy with aggressive antibiotics treatment to which the patient responded with resolution of the brain abscesses and recovery of power in affected limbs. This report aimed to highlight the need for increased suspicion of splenic abscesses in children who are apparently immunocompetent and to add to the knowledge of management of this rare condition in children. We conclude that splenic abscess with intracerebral abscess is a rare but life-threatening condition which is amenable to treatment with drainage of abscess and aggressive guided antimicrobial therapy.

Laparoscopic fenestration is the preferred treatment for symptomatic splenic cysts because it is curative and spleen-sparing. We report a case of a 25-year-old female who underwent laparoscopic fenestration for a giant splenic cyst using a single-incision plus one-port approach. She presented to our hospital with repeated vomiting. Imaging showed a 23 × 18 cm splenic cyst with no solid components, strongly compressing the stomach to the right side. Laparoscopic fenestration was initiated through a 2.5-cm umbilical incision, and a 5-mm port was added in the left abdomen intraoperatively. The drain placement was deemed necessary to prevent abscess formation and post-operative bleeding because of a thick cyst component and unexpectedly thick wall. Splenic cysts are typically benign and commonly develop in young people, hence, organ preservation and cosmetic results are crucial. Laparoscopic fenestration using single-incision plus one-port is considered to be an appropriate procedure for giant splenic cysts with non-serous contents.

OBJECTIVES: Splenic lesions might exhibit overlapping imaging features, varying from benign entities like cysts and hemangiomas to malignancies such as lymphoma and angiosarcoma. This meta-analysis aims to delineate imaging characteristics that distinguish malignant from benign splenic lesions. METHODS: Adhering to PRISMA guidelines, we searched PubMed, Scopus, and Web of Science for studies on imaging features differentiating malignant from benign splenic lesions. We extracted data on splenic pathology and imaging characteristics and assessed the methodological quality via QUADAS-2. Odds ratio meta-analyses were performed using STATA (Version 17.0, Stata Corp, College Station, TX). RESULTS: Portal phase hypoenhancement, hypovascular enhancement pattern, diffusion restriction, and late phase hypoenhancement, with odds ratios above 10, highly indicate malignancy. Other features suggestive of malignancy include solid morphology, lymphadenopathy, presence of perisplenic fluid, arterial hypoenhancement, hypoechogenicity on ultrasound, splenomegaly, and presence of multiple lesions. In contrast, cystic morphology, hypervascular-washout and hypervascular-persistent pattern of enhancement, late phase hyperenhancement, anechogenicity on ultrasound, portal phase hyperenhancement, well-defined borders, and calcification are in favour of benign pathology. CONCLUSION: The study underscores the critical role of contrast-enhanced and diffusion-weighted imaging in distinguishing malignant from benign splenic lesions, emphasizing the role of features like portal phase hypoenhancement and restricted diffusion in diagnosing malignancies. Additionally, the study emphasizes the value of contrast-enhanced ultrasound, which allows for the visualization of key contrast-enhancement patterns without the risk of ionizing radiation exposure.

BACKGROUND: Splenic sequestration crisis is a potentially fatal complication of sickle cell disease, mainly seen in young children. Only a few case series describe the acute splenic sequestration crisis in adults and its management, which primarily consists of supportive care and, in some cases, splenectomy. Splenic artery embolization has seldom been described in sickle cell disease. This is probably the first case in which an adult with sickle cell disease presented with an acute splenic sequestration crisis was managed successfully through splenic artery embolization. RESULTS: This 22-year-old female, a known case of sickle cell disease, presented with severe pain in the abdomen and low-grade intermittent fever for two days, secondary to an acute splenic sequestration crisis. The diagnosis of acute splenic sequestration was made based on clinical and blood parameters, ultrasonography, and computed tomography. Even with adequate supportive care and blood transfusions, the patient's condition worsened with a rapid fall in the hemoglobin and total platelet count. Considering splenectomy to be a high-risk procedure for this patient, a decision of rescue splenic artery embolization was taken, which was successful. CONCLUSION: Splenic artery embolization may be considered a lifesaving procedure in patients with acute splenic sequestration, where the risk of splenectomy can be high. Adequate post-procedure supportive care is vital for preventing complications.

AIM: Our aim was to investigate the frequency of various splenic cysts, to define the sonographic differential diagnostic clues and to introduce the value of twinkling artefact in the diagnosis of epidermoid splenic cysts. MATERIAL AND METHODS: All the splenic cysts imaged by ultrasound in 3 university hospitals during the period of 2005 to 2022 were recorded, followed-up and analyzed. RESULTS: One hundred seventy-one patients with splenic cysts were detected and these were classified and 73% of the cysts were simple. Ten cysts were epidermoid cysts as proven by post-operative final histology. CONCLUSION: Cystic splenic lesions are rare. Most of them are small simple cysts. Epidermoid cysts are larger in volume, constitute 6% of the total and can be differentiated by the help of twinkling artefact by Doppler ultrasound.

BACKGROUND: Wandering spleen (or ectopic spleen) refers to a hyper-mobile spleen resulting in its displacement from the normal anatomical position to usually in the lower abdominal or pelvic cavity. While ultrasound is often the first radiological modality used, Computed Tomography (CT) shows a clear picture and aides to reach a diagnosis. In circumstances where appropriate imaging modalities are not available, or the operator is inexperienced, diagnosis of wandering spleen can be missed. CASE PRESENTATION: A 22-nulligravida unmarried Sindhi female had presented to the Emergency Room (ER) with a 5-day history of intermittent severe lower abdominal pain. An ultrasound at a local practitioner had suggested an ovarian cyst. Ultrasound-pelvis and later CT scan at our facility reported an enlarged wandering spleen with torsion of its pedicle and infarction. Exploratory laparotomy with splenectomy was done. An enlarged wandering spleen was found with torsion of the splenic vein and thrombosed arterial supply from omentum wrapped over the mass. The patient developed thrombocytosis post-surgery but otherwise did well and was discharged after 2 days. CONCLUSION: Splenic torsion secondary to a wandering spleen can be challenging to diagnose, especially in resource limited settings where ultrasound might be the only modality available. Timely diagnosis and proper intervention are key to saving the life and the spleen.

BACKGROUND: Gastrosplenic fistula is a rare and potentially fatal complication of various conditions. Lymphoma is the most common cause. It can occur spontaneously or after chemotherapy. Gastrosplenic fistula diagnosis can be confused with a splenic abscess because of the presence of air into the mass. The computed tomography identification of the fistulous tract is the key to a right diagnosis. Treatment modalities include surgical resection, chemotherapy, or a combination of both. CASE PRESENTATION: Here we report two patients with gastrosplenic fistula due to diffuse large B cell lymphoma. The first patient was a 54-year-old Caucasian woman with an enormous primary splenic diffuse large B cell lymphoma leading to the development of a spontaneous fistula in the stomach. The second patient was a 48-year-old Caucasian male patient with an enormous splenic diffuse large B cell lymphoma complicated by fistula after chemotherapy. Both patients died of septic shock several days after surgery. CONCLUSION: Gastrosplenic fistula is a rare complication with a poor-prognosis, for which surgery is currently the preferred treatment.

The presence of a splenic subcapsular hematoma (SCH) has been associated with higher rates of failure of nonoperative management (FNOM) in patients with blunt splenic injury (BSI), with rates up to 80%. We hypothesized that contemporary rates are lower. A retrospective review was conducted of patients admitted with BSI to a level I trauma center (2016-2021). Patients with SCH who had FNOM were compared to those who did not. There were 661 BSI patients, of which 102 (15.4%) had SCH. Among the SCH patients, 8 (7.8%) had FNOM. Failure of nonoperative management was higher in patients who had a SCH measuring 15 mm or greater. To the best of our knowledge, this is the largest study to date examining the relationship between SCH and FNOM. The presence of a SCH alone is not associated with a high risk for FNOM contrary to previous literature. However, SCH thickness was larger in those who failed.

Xanthogranulomatous inflammation is a chronic inflammatory reaction microscopically characterized by aggregation of foamy histiocytes, fibrous tissue, and infiltration of various inflammatory cells. In contrast to xanthogranulomatous inflammation in the gallbladder or kidney, xanthogranulomatous pancreatitis is rare. We herein present a case of xanthogranulomatous pancreatitis in a patient who underwent distal pancreatectomy with splenectomy under preoperative suspicion of a pancreatic pseudocyst or pancreatic tumor. A 77-year-old woman with a 1 month history of epigastric pain, anorexia, and general fatigue was admitted to our hospital. Contrast-enhanced computed tomography revealed a cystic mass with ill-defined margins at the pancreatic tail together with a splenic abscess. Contrast-enhanced endoscopic ultrasound detected a hyperechoic cystic lesion at the tail of the pancreas with heterogeneous internal echogenicity, and part of the intra-cystic content was enhanced by the contrast agent. Endoscopic retrograde cholangiopancreatography showed a cystic lesion at the tail of the pancreas that continued into the main pancreatic duct, and the main pancreatic duct was slightly narrowed downstream of the cystic lesion. Pancreatic juice cytology revealed suspicious cells, leading to the possibility of intraductal papillary mucinous carcinoma. Distal pancreatectomy with splenectomy was performed, and the histopathological diagnosis was xanthogranulomatous pancreatitis with no malignant findings.

Hydatidosis is an endemic disease in certain areas in the world particularly in the Mediterranean, the Middle East, and South America, caused by a cestode known as Echinococcus granulosus. Humans are the accidental intermediate hosts. The liver and the lungs are the most commonly involved organ. If the parasite passes through the pulmonary capillary bed, the hydatid cyst may develop at any site in the body like bone, pancreas, brain, kidney, and orbit. Isolated spleen hydatid cyst is very rare. We hereby report one observation of isolated hydatid cyst of the spleen in a patient living in non-endemic area and without any potential risk.

BACKGROUND: Splenic cysts are quite rare and asymptomatic. They may result from infection by a parasite, especially Echinococcus granulosus (hydatid cyst), or from non-parasitic causes. Since primary splenic cysts are not common, simple cysts can be misdiagnosed with a hydatid cyst in endemic areas. CASE PRESENTATION: We reported a 14-year-old Iranian girl initially presented with a vague abdominal pain, which progressed to left shoulder pain, fullness, early satiety, and shortness of breath and remained undiagnosed for 7 months despite seeking medical attention. Finally, imaging revealed a massive splenic cyst measuring 220 mm × 150 mm × 160 mm raising concern for a hydatid cyst due to regional endemicity. Consequently, the patient underwent total splenectomy. However, histopathological examination surprisingly revealed a simple non-parasitic cyst. CONCLUSIONS: Detecting rare simple spleen cysts requires early ultrasonography (US) and careful reassessment of diagnoses for non-responsive or worsening symptoms. Distinguishing them from splenic hydatidosis, especially in endemic areas, demands thorough paraclinical evaluations and patient history regarding potential parasitic exposure. While total splenectomy is the primary treatment for these huge cysts, the optimal surgical approach should be tailored case by case. These insights emphasize a comprehensive diagnostic approach to enhance accuracy and optimize patient care for these uncommon cysts.

We present a sclerosing angiomatoid nodular transformation (SANT) case report in a 60 year-old-woman. SANT is an extremely rare benign disease of the spleen that it is radiologically similar to malignant tumors, and clinically difficult to differentiate from other splenic diseases. Splenectomy is both diagnostic and therapeutic in symptomatic cases. The analysis of the resected spleen is necessary to achieve the final diagnosis of SANT.(AU)

BACKGROUND: Splenic tumors are rare and can pose a differential diagnostic challenge, especially as an incidental imaging finding. Due to a lack of large scale biopsy studies the available literature is limited with respect to clear imaging criteria for dignity. OBJECTIVE: The present work is intended to show the chances of a targeted elicitation of the medical history as well as the possibilities and limitations of multimodal sonography in order to achieve the correct diagnosis of a splenic lesion using simple and gentle methods. MATERIAL AND METHODS: Selective literature search and clinical case studies. RESULTS: In the differential diagnostics of focal splenic lesions, information about pre-existing hemato-oncological or inflammatory rheumatological diseases is essential in order to correctly classify incidental findings in particular. In addition to Bmode ultrasound (B-US) and color-coded Doppler ultrasound (CD-US), contrast-enhanced ultrasound (CEUS) in particular provides crucial differential diagnostic information. While hyperechoic foci in BUS or arterially hypervascularized splenic foci in CD-US/CEUS are usually benign, hypoechoic and arterially hypoperfused foci in CD-US/CEUS must be further clarified. Although the ultrasound-guided biopsy of the spleen has a higher risk of bleeding than a liver biopsy, it is still the gentlest and most effective method for achieving the histological clarification of splenic lesions when the indications are correct. CONCLUSION: Through the combination of the medical history and multimodal ultrasound methods, if necessary supplemented by an ultrasound-guided biopsy, focal splenic lesions can be successfully classified in most cases with a direct impact on further clinical procedures.

The correct indications for surgical treatment of primary splenic tumors as well as metastases of the spleen are challenging due to the rarity of the various entities. Primary solid splenic tumors include benign lesions, such as hemangiomas, hamartomas and sclerosing angiomatous nodular transformation (SANT) of the spleen. In these cases, surgical treatment is indicated only in the case of inconclusive imaging and after careful consideration of the risk-benefit ratio, even in the case of pronounced symptoms. In contrast, primary angiosarcoma or undifferentiated pleomorphic sarcoma as highly malignant tumors represent an urgent indication for surgery. Although more frequent than primary splenic malignancies, secondary splenic tumors are also not that frequent. Solitary splenic metastases are rare; however, from an oncological point of view they can be treated by resection. In the case of oligometastasis with splenic involvement, splenectomy is used only as part of a palliative concept in cases of pronounced symptoms or in the context of cytoreductive surgery. In general, the laparoscopic approach is to be preferred when the operation is technically feasible as it is associated with fewer pulmonary and infectious complications and a shorter hospital stay. In addition, to reduce the risk of severe infections after splenectomy, the option of partial splenectomy should be considered, especially for benign lesions. A thorough informing of the patient regarding both intraoperative and perioperative risks as well as potential long-term sequelae, especially severe infectious diseases, is an essential component of informed consent before surgery.
