“…Although the final diagnosis of splenic hamartomas is established by a pathological examination, a preoperative diagnosis using a combination of multi-modality imaging techniques may be possible [9,12-14]. On sonography, most hamartomas are hyperechoic relative to the adjacent normal splenic parenchyma [15].…”

“…Some splenic hamartomas are homogeneous and well-defined solid masses, with varying echogenicity relative to the normal splenic parenchyma, but others may be heterogeneous with cystic changes [12,16]. Colour Doppler sonography may reveal blood-flow signals within the lesions [14]. Splenic hamartomas do not always exhibit hypervascularity because some are hypoechoic and are composed of red pulp, lacking fibrous trabeculae and white pulp [16].…”

“…However, the hypoechoic lesion in patient 2 contained a mixture of unorganised vascular channels and fibrotic cords of splenic red pulp-like areas on histological examination. On unenhanced CT images, most splenic hamartomas are homogeneous, or heterogeneous low-density or isodense masses with occasional calcification [12,14]. Histopathological fibrous splenic hamartomas have a dominant fibrous tissue and MRI showed isointensity or hyperintensity on T1WI images and hypointensity on T2WI images [17].…”

Hamartomas are extremely rare splenic benign tumours in children. We present two cases, both in boys (6 and 8 years old), with left upper quadrant abdominal pain that were otherwise asymptomatic. Both patients showed a splenic mass on preoperative ultrasonography and magnetic resonance imaging (MRI). One patient had a focal splenic mass that was identified preoperatively with contrasted computed tomography (CT) scans. Both patients underwent a total splenectomy. Although multi-modality imaging findings were described preoperatively, the final diagnosis in each case was splenic hamartoma based on histology and immunohistochemistry. The postoperative courses were uneventful.

Hamartoma is a rare splenic benign tumor usually accidentally detected as a radiologic finding. Preoperative diagnosis poses a challenge and thus surgery becomes necessary to confirm the clinical suspicion. Laparoscopic splenectomy has gained consensus as a standard surgical procedure particularly for autoimmune hematological diseases. This former experience has allowed this technique to be extended to other splenic pathologies. Here we report a case of total laparoscopic splenectomy for a bulky splenic hamartoma in a young male patient.

Objective: Ultrasound contrast agents in conjunction with contrast specific imaging techniques, are increasingly accepted in clinical use for diagnostic imaging in several organs. Contrast enhanced sonography (CES) of second generation contrast media have shown a spleen-specific uptake of the microbubble contrast agent. The aim of this review is to illustrate indications for the use of CES in patients with suspected (peri-)splenic pathology.Methods: This pictorial review based on the experience of transcutaneous CES in 180 consecutive adult patients with (peri-)splenic pathology diagnosed by B-mode sonography at an internal medicine center. CES studies were performed with a contrast-devoted unit (Acuson, Sequoia, Siemens medical solution) that had contrast-specific, continuous-mode software. A low mechanical index was used. A sulfur hexafluoride-based microbubble contrast medium (Sonovue ® , Bracco SpA, Milan, Italy) was injected.Results: On our experience there are six clinical conditions which indicates the use of CES for diagnosis of (peri-)splenic pathology: 1. the perisplenic tumor, 2. the small sized spleen, 3. the inhomogenous spleen of unknown cause, 4. the incidentally found hypoechoic splenic tumor, and 5. pain in the left upper quadrant, and 6. patients with blunt abdominal trauma. CES is of value 1. to diagnose or exclude accessory spleen, 2. to diagnose functional asplenia/hyposplenia, 3. to diagnose focal lesions in an inhomogenous spleen, 4. to diagnose high vascular splenic hemangioma, 5. to diagnose or exclude splenic infarction and splenic abscess, and 6. to diagnose splenic laceration.Conclusion: CES is of diagnostic value in several clinical circumstances to diagnose accessory spleen, functional asplenia, small sized splenic involvement, high vascular splenic hemangioma, and vascular splenic pathology like splenic infarction, splenic abscess, and splenic laceration.
