Normal spleen

(from http://idhumanbody.com)

Ectopic spleen in a dog. A small rounded structure (arrow) is present along the mesenteric side of the spleen, near the hilus.  It has similar echogenicity and echotexture as the spleen (Sp). Such tissue may be misinterpreted as an enlarged lymph node or metastatic nodule.

Sagittal ultrasound image of the left cranial abdomen over the palpated mass demonstrating a 10 cm diameter inhomogeneous swelling continuous with the spleen with hypo- and hyperechogenic areas. The surrounding tissue is hyperechogenic.

Image of the spleen from a dog prior to induction of shock. Contrast-enhanced ultrasound of the spleen indicating the presence of active bleeding, where contrast medium extravasation and pooling (red arrow) were observed.

Image of the spleen from a dog in traumatic hemorrhagic shock. Contrast-enhanced ultrasound of the spleen. The splenic lesion appeared as an anechoic perfusion defect area with an unclear irregular border (red arrows), suggesting the absence of active bleeding.

Conventional ultrasound imaging (A) and perflubutane microbubbles-enhanced imagings (B–E) of splenic carcinoma. (B) Immediately after injection, similar pattern vessel was visualized (arrow) in the lesion (arrowheads). (C) During the early vascular phase, the lesion was isoechoic (arrowheads) compared with the surrounding normal parenchyma. (D) During the late vascular phase, the lesion became hypoechoic (arrowheads) compared with the surrounding normal parenchyma. (E) During the parenchymal phase, the lesion was hypoechoic (arrowheads).

Conventional ultrasound imaging (A) and perflubutane microbubbles-enhanced imagings (B–E) of splenic nodular hyperplasia. (B) Immediately after injection, similar pattern vessel was visualized (arrow) in the lesion (arrowheads). During both (C) the early vascular phase and (D) late vascular phase, the lesion was isoechoic (arrowheads) compared with the surrounding normal parenchyma. (E) During the parenchymal phase, the lesion became hypoechoic (arrowheads).

Conventional ultrasound imaging (A) and perflubutane microbubbles-enhanced imagings (B–E) of splenic hematoma. (B) Immediately after injection, no vessel was visualized in the lesion (arrowheads). During both (C) the early vascular and (D) the late vascular phase, the lesion was heteroechoic (arrowheads). (E) During the parenchymal phase, the lesion became hypoechoic (arrowheads).

Conventional ultrasound imaging (A) and perflubutane microbubbles-enhanced imagings (B–E) of splenic hemangiosarcoma. During the early vascular phase, (B) the tortuous vessel (arrow) and (C) aberrant wide vessel (arrow) were visualized, but the entire lesion was hypoechoic (arrowheads). (D) During the late vascular phase, the lesion remained hypoechoic (arrowheads) with visualization of vessels (arrow). (E) During the parenchymal phase, the lesion became hypoechoic (arrowheads).

Observation of hematomas by conventional US, CEUS and CT. (A) Conventional US showed a heterogeneity hypoechoic region in the spleen with a poorly defined margin (white arrow). (B) The hematoma lesions were clearly identified by CEUS, which showed the lesions as anechoic perfusion defects in the arterial, portal, and late phases, lasting approximately 5 min (white arrow). (C) CT examination demonstrated that the volume of the spleen increased with a round or oval shape of a lower density (white arrow).

Observation of hematomas after rupture by conventional US, CEUS and CT. (A) Conventional US showed a slightly hyperechoic region, with an unclear boundary (white arrow). (B) CEUS showed perisplenic hemoperitoneum, discontinued spleen capsule and the large lamellar and irregular anechoic areas in the parenchyma with a clear margin (white arrow). (C) CT examination showed the irregular and unenhanced areas in the spleen parenchyma with discontinued spleen capsule (white arrow).
