Hamartomas are tumours composed of mesenchymal tissues such as cartilage, fat, connective tissue and smooth muscle and can be found in virtually any organ system. These masses commonly develop sporadically, but are also seen in certain syndromes such as tuberous sclerosis or Carney triad. While their imaging appearance varies depending on the organ they arise from, findings are usually unique and a diagnosis can be confidently made. Radiologists must be aware of the clinical and imaging presentations of these lesions with the particular goal of avoiding unnecessary studies or invasive procedures. Furthermore, knowledge of common syndromic entities is crucial, as the radiologist may be the first to suggest the diagnosis.

“…Calcification of splenic lesions is rare, although it may occur following treatment [1,4]. On MRI, splenic nodules are low to intermediate in signal on T 1 weighted images, mild to moderately hyperintense on T 2 weighted images and hypoenhancing compared with the spleen on postgadolinium images [9]. The normal spleen shows a uniform homogeneous appearance on non-contrast scans, inhomogeneous enhancement in the early phase and uniform enhancement on the venous phase [1].…”

“…On MRI, the signal intensity of the fungal lesions usually varies depending on the treatment and phase of disease [6]. Acute splenic fungal lesions appear as multiple, subcentimetre rounded lesions, which are hypointense on T 1 weighted images, hyperintense on T 2 weighted images ( Figure 16) with rim enhancement on post-contrast MRI [6,9,24]. Hypoenhancement, less uniformity and relatively larger lymphoma nodules help to differentiate lymphoma deposits from fungal nodules, which often have central or rim enhancement.…”

ABSTRACT. Imaging morphology and metabolic activity of splenic lesions is of paramount importance in patients with haematological malignancies; it can alter tumour staging, treatment protocols and overall prognosis. CT, MRI and positron emission tomography (PET)/CT have been shown to be powerful tools for the noninvasive assessment of splenic involvement in various haematological malignancies. Since many haematological malignancies and non-neoplastic conditions can involve the spleen and imaging manifestations can overlap, imaging and clinical findings outside of the spleen should be looked for to narrow the differential diagnosis; confirmation can be obtained by pathological findings. Radiologists should be familiar with the cross-sectional imaging patterns of haematological malignancies involving the spleen as well as non-neoplastic splenic findings common in these patients to facilitate their care and follow-up. This pictorial review provides the common and uncommon imaging appearances and complications of various haematological malignancies involving the spleen on CT, MRI and PET/CT, and common pitfalls in diagnosis.
