Symptomatic splenic hamartomas are rare in the pediatric age group, with only four previous reports in the literature. Splenic hamartoma has been reported as a solid homogeneous mass without calcification on CT and ultrasound (US), and only one previous report of the findings on MRI has been published. We report a case of a large symptomatic splenic hamartoma in a 14-year-old girl who presented with splenomegaly, pancytopenia and growth retardation. A solid mass with multiple punctate foci resembling calcifications was seen on US. The mass was heterogeneous and better demarcated on enhanced CT. Radiocolloid scintigraphy demonstrated uptake within the lesion, but less than that of normal spleen. The mass was isointense relative to normal splenic tissue on T1-weighted MRI (0.5 T) and of increased intensity with T2 weighting. At splenectomy, a red pulp hamartoma was identified, which contained nodules of hyalinization and necrosis thought to account for the punctate foci seen on US.

Mediastinal lymphangiomas are rare benign tumors arising from lymphatic system malformations, most commonly seen in pediatric populations. In adults, they are exceedingly rare and present diagnostic challenges due to nonspecific symptoms and imaging overlap with other mediastinal masses. Diagnosis is typically based on imaging, including CT and MRI, with histopathology confirming the diagnosis.

Introduction: Extramedullary hematopoiesis (EMH) is very rarely described during sickle cell disease (SCD). Our aim was to describe six cases of EMH occurring in adult SCD patients and to conduct a literature review.
Methods: Retrospective, descriptive, and monocentric study, identifying all cases of EMH recorded in our cohort of adult SCD patients, up to April 2024.

Background: Generalized lymphatic anomaly (GLA) is a rare congenital lymphatic malformation (LM) characterized by multiple infiltrating lymphangiomas in various tissues. Owing to its rarity, information on this disease is obtained mainly through case reports, leading to delayed diagnosis. In this study, we reported a case of generalized lymphatic anomaly in a pediatric patient manifesting as hemorrhagic pleural effusion.

Splenic cysts are rare medical conditions, and their incidence is dominated by parasitic types. Non-parasitic splenic cysts, whether true cysts (with a cellular lining of the cystic wall) or pseudocysts (without a cellular lining), are significantly rarer than parasitic ones. Their etiology is not fully established, with fetal remnant development, metaplasia, and mesothelial invagination being widely accepted possible mechanisms.

Background: Portal venous system aneurysms (PVA) are increasingly diagnosed on cross-sectional computed tomography (CT) imaging. However, the natural history of these aneurysms is poorly understood and reports are limited to small case series.
Methods: Terms relevant to PVA were searched in radiology reports (2010-2022) with PVA presence confirmed by manual review.
