“…MRI will show a lesion, which is hypointense on T2-weighted sequences and hyperintense on T1-weighted sequences. The mass shows a relatively homogeneously enhancing mass in the spleen on contrast MRI images (7). Splenic hamartomas show hypointensity on DWI.…”

“…On MRI, the lesions usually appear with mixed T1 and T2 signal intensity due to necrosis and hemorrhage. In addition, contrast enhancement is variable, and heterogeneous enhancement may be demonstrated (7). Hemangiomas are the most common benign vascular tumors and showcase a well-demarcated homogenous hypoechoic or hyperechoic lesion on ultrasound.…”

“…The contrast MRI images of hemangiomas are characterized by a gradual, progressive enhancement in the portal venous and delayed phases. DWI sequences show the nodule to be hyperintense (7). Hamartomas are rare, benign lesions of the spleen and showcase a well-demarcated homogenous lesion with or without cystic center on ultrasound.…”

“…3. Given that the splenic hamartoma is a solid mass with clear boundary, isointensity on T1WI and hyperintensity on T2WI, with heterogeneous enhancement in the early stage, and a similar signal compared to the surrounding spleen parenchyma in the later stage, it is not difficult to distinguish from IPT-like FDCS ( 21 ). 4.…”

BackgroundInflammatory pseudotumor-like follicular dendritic cell sarcoma (IPT-like FDCS) is a rare subtype of follicular dendritic cell sarcoma (FDCS) that is mainly located in the liver and spleen (1). Splenic IPT-like FDCS is a rare low-grade malignancy with non-specific clinical manifestations and laboratory findings. Herein, we reported the pathological and imaging features of a case with splenic IPT-like FDCS.Case presentationA 57-year-old woman was found to have a mass in the spleen during a physical examination and was hospitalized for further treatment. Her laboratory results were within the normal range. Unenhanced and contrast-enhanced computed tomography scans of the whole abdomen showed a round mass in the spleen, with a diameter of about 5 cm. After further examination with enhanced MRI, a provisional diagnosis of splenic hemangioma or splenic hamartoma was made. The patient underwent splenectomy, and the pathological diagnosis was splenic IPT-like FDCS. No tumor recurrence or metastasis was found during the 1-year follow-up after the operation.ConclusionsHerein, we reported a case of splenic IPT-like FDCS. Although the clinical examination and laboratory examination lack specificity, the imaging of this case showed that the lesion was a solid mass with progressive enhancement, and the central scar showed the characteristics of delayed enhancement, which facilitated the diagnosis.

BACKGROUND The overlap of imaging manifestations among distinct splenic lesions gives rise to a diagnostic dilemma. Consequently, a definitive diagnosis primarily relies on histological results. The ultrasound (US)-guided coaxial core needle biopsy (CNB) not only procures sufficient tissue to help clarify the diagnosis, but reduces the incidence of puncture-related complications. CASE SUMMARY A 41-year-old female, with a history of pulmonary tuberculosis, was admitted to our hospital with multiple indeterminate splenic lesions. Gray-scale ultrasonography demonstrated splenomegaly with numerous well-defined hypoechoic masses. Abdominal contrast-enhanced computed tomography (CT) showed an enlarged spleen with multiple irregular-shaped, peripherally enhancing, hypodense lesions. Positron emission CT revealed numerous abnormal hyperglycemia foci. These imaging findings strongly indicated the possibility of infectious disease as the primary concern, with neoplastic lesions requiring exclusion. To obtain the precise pathological diagnosis, the US-guided coaxial CNB of the spleen was carried out. The patient did not express any discomfort during the procedure. CONCLUSION Percutaneous US-guided coaxial CNB is an excellent and safe option for obtaining precise splenic tissue samples, as it significantly enhances sample yield for exact pathological analysis with minimum trauma to the spleen parenchyma and surrounding tissue.
