AIM:To establish the safety and feasibility of laparoscopic splenectomy(LS) for littoral cell angioma(LCA).METHODS:From September 2003 to November 2013,27 patients were diagnosed with LCA in our institution.These patients were divided into two groups based on operative procedure:LS(13 cases,Group 1) and open splenectomy(14 cases,Group 2).Data were collected retrospectively by chart review.Comparisons were performed between the two groups in terms of demographic characteristics(sex and age); operative outcomes(operative time,estimated blood loss,transfusion,and conversion); postoperative details(length of postoperative stay and complications); and follow-up outcome.RESULTS:LS was successfully carried out in all patients except one in Group 1,who required conversion to hand-assisted LS because of perisplenic adhesions.The average operative time for patients in Group 1 was significantly shorter than that in Group 2(127 ± 34 min vs 177 ± 25 min,P = 0.001).The average estimated blood loss in Group 1 was significantly lower than in Group 2(62 ± 48 m L vs 138 ± 64 m L,P < 0.01).No patient in Group 1 required a blood transfusion,whereas one in Group 2 required a transfusion.Two patients in Group 1 and four in Group 2 suffered from postoperative complications.All the complications were cured by conservative therapy.There were no deaths in our series.All patients were followed up and no recurrence or abdominal metastasis were found.CONCLUSION:LS for patients with LCA is safe and feasible,with preferable operative outcomes and longterm tumor-free survival. 展开更多

A littoral cell angioma(LCA) is a primary vascular tumor of the spleen, that can have malignant potential and may present association with other malignancies. This is a case of LCA that was discovered incidentally in a 79-year-old woman who presented with a polycythemia at the time of consultation. The neoplasm was evaluated by ultrasound and computed tomography. The patient underwent a splenectomy that revealed LCA by pathological evaluation. The post-operative outcome was favorable with no complications or recurrent disease. This case presentation, clinical, radiographic, and pathological features of an uncommon splenic tumor can be studied in order to advance our knowledge in our understanding of LCA. 展开更多

Primary splenic lesions are rare entities among which littoral cell angioma(LCA) is a recently described, uncommon vascular lesion that is unique to the spleen. It has heretofore been described primarily in pathologic series and has been found mostly to behave as a benign entity. A few reports of malignant variants have been reported. We present a case report of a solitary LCA discovered after splenectomy for an incidentally discovered splenic lesion, along with a literature review. 展开更多

Littoral-cell angioma (LCA) is a primary splenic vascular tumor that arises from the normal littoral cells lining the sinus channels of the splenic red pulp. We report a case of LCA of the spleen, which has been infrequently communicated in the literature. A 76-year-old man with a 2-wk history of weight loss, abdominal pain and changes in bowel habits was admitted to our hospital. Imaging studies (CT and MR1) showed multiple lesions in the spleen. Splenectomy was performed. Lining cells were positive for CD31/CD68 markers. Our case was associated with a serrated colonic adenoma. LCA is a benign vascular tumor of the spleen that needs to be included in the differential diagnosis of multiple splenic nodules. 展开更多

BACKGROUND Littoral cell angioma(LCA)is a rare benign vascular tumor of the spleen.Given its rarity,standard diagnostic and therapeutic recommendations have yet to be developed for reported cases.Splenectomy is the only method of obtaining a pathological diagnosis and providing treatment to obtain a favorable prognosis.CASE SUMMARY A 33-year-old female presented with abdominal pain for one month.Computed tomography and ultrasound revealed splenomegaly with multiple lesions and two accessory spleens.The patient underwent laparoscopic total splenectomy and accessory splenectomy,and splenic LCA was confirmed by pathology.Four months after surgery,the patient presented with acute liver failure,was readmitted,rapidly progressed to multiple organ dysfunction syndrome and died.CONCLUSION Preoperative diagnosis of LCA is challenging.We systematically reviewed online databases to identify the relevant literature and found a close relationship between malignancy and immunodysregulation.When a patient suffers from both splenic tumors and malignancy or immune-related disease,LCA is possible.Due to potential malignancy,total splenectomy(including accessory spleen)and regular follow-up after surgery are recommended.If LCA is diagnosed after surgery,a comprehensive postoperative examination is needed. 展开更多

Objective To assess the characteristics of magnetic resonance imaging for spinal cavernous angiomas.Methods The examinations of plain scan and contrast enhanced scan of magnetic resonance were performed in three patients with spinal cavernous angiomas.Results The focus of two cases was located in thorax segment of the spinal cord and one in lower cervical segment.All focuses were single and the shape of spinal cord was normal or slightly thick. MRI characteristic of spinal cavernous angiomas was just like popcorn or mulberry with a jumbled gobbet signal. Low and short T 2 signal appeared around the focus. In all cases, there were no obvious contrast enhanced signal in 2 cases and one case with moderate contrast enhanced signal. The diameter of hemorrhage was smaller than that of the spinal cord.Conclusion MRI has higher sensitivity and specificity in the diagnosis of spinal cavernous angioma. 展开更多

Structural lesions of CNS, reported to be associated with torticollis, are mostly restricted to cerebellum, brain stem and basal ganglia. In fact, we know only about two documented frontal lobe mass lesions—meningiomas, associated with torticollis. Our observation of frontal lobe cavernous angioma associated with clinical picture of torticollis confirms the role this area could play in the pathophysiology of involuntary movements. We report a case of patient with torticollis associated with cavernous angioma of the right frontal lobe and presuppose causative role of angioma in the development of our patient’s torticollis. 展开更多

Background:Repeated intracranial hemorrhages caused by cardiac myxoma is very rare.It is essential for physicians to be aware of such uncommon clinical feature of myxoma.Case presentation:We report a-49-year-old female patient complained of repeated multiple intracranial hemorrhages,with no sign of cardiac dysfunction or cerebral infarction before admission.Cavernous angioma (CA) was misdiagnosded due to the clinical and magnetic resonance (MR) presentation.A sudden ischemic event after admission led to the finding of a left atrial myxoma.Conclusions:Repeated intracranial hemorrhages can be the early and primary clinical presentation of cardiac myxoma,probably caused by its metastasis,without obvious ischemic stroke or cardiac symptoms. 展开更多

Cerebral cavernous malformations are a rare and congenital vascular malformation that can present as a challenge in neurosurgical management. The term “giant cerebral cavernous malformations” still does not have a clear definition in the literature, with a wide variety of results. It is known, however, that there is an association between the size of the cavernoma and postoperative sequelae, especially in those with a size greater than 3 cm in its largest diameter. We present a case report of resection of a giant brain cavernoma measuring approximately 8 cm in its largest diameter, emphasizing on clinical presentation, diagnoses and postoperative evolution. Additionally, we performed a comprehensive review of the existing literature on the subject, addressing the epidemiology, pathophysiology, diagnostic methods, treatment options, and prognosis associated with this condition. 展开更多
