technetium-tc-99m-sulfur-colloid and Hematoma

While 99mTc sulfur colloid imaging, because of its availability and convenience, remains the initial procedure of choice for spleen imaging, selective spleen scanning with damaged 99mTc-labeled RBCs can provide additional information in some cases. These cases include overlapping left hepatic lobe and suspected splenic pathology but with poor radiocolloid uptake that precludes visualization. Other indications are detection of residual splenic tissue after splenectomy, suspected asplenia, polysplenia, and situs ambiguus. The selective 99mTc-denatured RBC scan is most useful to confirm or exclude defects seen on the radiocolloid study and to detect small amounts of splenic tissue.

The diagnosis of hepatic rupture in patients with pregnancy-induced hypertension (preeclampsia and eclampsia) is rarely made preoperatively. Diagnostic imaging can be utilized in some patients to confirm the preoperative diagnosis. Since hematoma formation precedes hepatic rupture, then, when diagnostic modalities such as sonography and computed tomography identify patients with hematomas, these patients are at risk of rupture, and should be hospitalized until the hematomas resolve.

An intrasplenic pancreatic pseudocyst may mimic a subcapsular splenic hematoma. Misdiagnosis of this entity may have serious consequences. Particular care should be taken when a patient presents with a cystic mass in the region of the spleen and a history of chronic alcohol abuse, regardless of the presence or absence of a history of a traumatic episode. Thin-needle aspiration is the current diagnostic modality of choice. A high fluid amylase level establishes the diagnosis of an intrasplenic pancreatic pseudocyst.
