In recent years, management of abdominal pain in emergency care units (ECU) has undergone a radical change. Chronic work overload of ECU and increase in severity and complexity of cases required an optimal medical imaging method, such as ultrasound, to establish an accurate diagnosis as quickly as possible. A great variety of causes may cause acute abdominal pain and the role of sonography is to accurately distinguish between these aetiologies. For the application of sonography, perhaps more so than with other imaging methods, a perfect knowledge of sonographical characteristics and technical possibilities is essential to achieve an optimal answer. The purpose of this review is to present and discuss the sonographic characteristics of extra-digestive causes of acute abdominal pain such as splenic infarction, thoracic pathologies, urinary and gynaecologic diseases or retroperitoneal pathologies.

Torsion of a wandering spleen is a rare cause of abdominal pain in children. The most common presentation is acute abdominal pain, although signs and symptoms vary widely. Due to the risk of splenic infarction, rapid and accurate diagnosis is essential. Wandering spleen and splenic torsion can be diagnosed by Doppler ultrasound and CT scan. Treatment options include splenopexy or splenectomy. This case describes a 9-year-old girl with torsion of a wandering spleen, complicated by splenic infarction and managed by splenectomy.

Many etiologies lead to pleural effusion. The pathogenetic cause is usually located either in the lung parenchyma or in the pleura. Subphrenic causes that lead to pleural effusion are uncommon. Several reports elaborated on the role of splenic hemorrhages in the genesis of left-sided pleural effusion. Splenic infarction is a rare etiology of left-sided pleural effusion, and it has rarely been described in medical literature. We present a case study of an elderly female patient who suffered from polycythemia vera for more than a decade, and was hospitalized for left-sided pleural effusion that appeared following left upper abdominal pain.

Very rare cases of abdominal organ infarction after surgery of primary lung cancer were reported. Case 1: Patient 1 was a 70-year-old man who underwent left upper lobectomy and ND 2a in June 1999 based on the clinical diagnosis of stage IA lung cancer. On the 4th postoperative day, the patient developed fever and right flank pain. Abdominal computed tomography (CT) demonstrated a specific finding compatible with renal infarction. The etiology could not be determined. The patient was treated conservatively. However, severe atrophy of right kidney was demonstrated by following CT performed 3 years later. Case 2: Patient 2 was a 70-year-old woman who underwent left upper lobectomy and ND 2a in December 2002 based on the clinical diagnosis of stage IA lung cancer. On the 4th postoperative day, the patient developed abdominal pain in the left upper quadrant, nausea and vomiting which had lasted for 10 days. Abdominal CT demonstrated a wedge-shaped filling defect at spleen compatible with splenic infarction. The etiology could not be determined. The patient was treated conservatively with prophylactic antibiotic therapy and followed closely. Partial atrophy of spleen was demonstrated by following CT performed 4 months later.

Thrombo-embolic events in coronary and peripheral arteries, and cerebral, pulmonary, portal, hepatic, and deep veins are seen in 27-45% of patients with polycythemia vera (PV). A 79-year-old man was admitted with complaints of pruritus increasing after bath and left upper abdominal pain radiating to left shoulder for two months. On physical examination, ruddy and hyperemic appearances of his face and conjunctiva, tenderness on the left upper quadrant, and splenomegaly were noted. Hemoglobin level was 16.6g/dl, hematocrit 53.8%, white blood cell count 26x10(9)/l, and platelet count 1.032x10(9)/l. Bone marrow aspiration and biopsy revealed hypercellularity, megakaryocytic hyperplasia and dysplasia. The leukocyte alkaline phosphatase score was 190. The levels of serum vitamin B12 and D-dimer were 316 pg/ml and 744 ng/ml, respectively. Arterial O2 saturation was 96%. Red cell mass was measured as 43 ml/kg using radionuclide 51Cr labelled erythrocyte scintigraphy. On cytogenetic analysis, deletion of 20q was found. Computed tomography of whole abdomen showed diffuse splenomegaly and two hypodense areas indicating splenic infarction in 2.5x2 and 3.5x3 cm diameters in subcapsular localization of the spleen. The patient was treated with therapeutic platelet-apheresis, 40 mg/day aspirin, analgesic drugs, and 3g/day hydroxyurea. After 1.5 months, platelet counts dropped to less than 500x10(9)/l and splenic infarcts were not detected on computed tomography. Splenic infarction may be the first evidence of thrombosis in PV. The reduction of platelet counts with platelet-apheresis, anti-platelet drugs, and careful clinical observation may be satisfactory in the treatment of splenic infarction.

Hemoglobinopathy S, Depranocytosis or Sickle Cell Disease is the most common hemoglobinopathy in the world. In its heterozygous form (Sickle Cell Trait), it affects 8% of the black population in the U.S. and 25% of the black population in Africa, and is found less frequently in the Mediterranean area, India, Middle East and Latin America. The basic alteration is a substitution of glutamic acid by valin in the sixth position of the beta globin chain, which causes polymerization at low oxygen tension thereby distorting the structure of erythrocytes and increasing blood viscosity, which, in turn, generates obstructions of the capillary arterial blood flow to different areas of the body thus causing microinfarctions. Although Splenic Infarction is rare, it is recognized as a serious complication of Heterozygous Sickle Cell Disease (Sickle Cell Trait). We present the case of a 21 year-old mestizo male patient who came in with an acute case of abdominal pain after arriving to work in the Casapalca mining city (located in the Peruvian Andes at 4200 m.a.s.l.) and was referred to our Hospital in Lima for exams. We present the case because it is an unusual cause of acute abdominal pain, and because this condition is rare in Peru and there are few publications about it.

A 28-year-old Malay woman presented with recurrent abdominal pain for five years. She had delivered her child seven months earlier. She was found to have bicytopenia, with a haemoglobin level of 7.9 g/dL and a platelet count of 85 x 10(9)/L. Computed tomography revealed a wandering spleen. Complications of a wandering spleen, for which splenectomy is advocated, include functional asplenia (due to torsion of the splenic pedicle), splenic infarction or splenic vessel thrombosis. A splenectomy was performed and at operation, splenomegaly with a long mesentery was found. Splenic histology was negative for malignancy. The bicytopenia resolved postoperatively, and she remains well.

We describe the first patient with hereditary spherocytosis (HS) known to have developed splenic infarction following infectious mononucleosis (IM). An 18-year-old Japanese man was referred to our hospital in November 2004 because of continuous fever and icterus. He had undergone cholecystectomy at the age of 14 years. On patient admission in November 2004, a physical examination showed marked hepatosplenomegaly, icterus, and jaundice. He had a white blood cell count of 14.9 x 10(9)/L with 9.5% atypical lymphocytes, a red blood cell count of 2.93 x 10(12)/L, and a hemoglobin concentration of 7.8 g/dL. Microspherocytes were observed in the patient's peripheral blood smear, and immunoglobulin M antibody to Epstein-Barr virus (EBV) viral capsid antigen was detected. The patient's diagnosis was HS with IM. On day 4 of admission, the patient complained of severe abdominal pain. Abdominal computed tomography scanning revealed findings of splenic infarction. Two months after the occurrence of splenic infarction, a splenectomy was performed. A pathohistologic examination of the resected spleen revealed no evidence of thrombosis or arterial occlusion. We assume that the cause of splenic infarction was insufficient blood flow to oxygenate the entire spleen during the acute enlargement of the spleen.

Systemic embolization is the most common extracardiac complication of active infective endocarditis (IE). The assessment of individual patient risk for embolic events in active IE is very difficult. Staphylococcal or fungal endocarditis, infections caused by HACEK and Abiotrophia spp. microorganisms, anterior mitral leaflet vegetations and vegetations with size >10 mm in TTE are associated with higher rate of arterial embolization. In this report we present a 66-year-old patient with active enterococcal aortic native valve endocarditis, with a history of gastric ulcers and with acute abdominal pain due to splenic infarction. We conclude that abdominal pain, particularly in the left-upper-quadrant, may be a sign of splenic infarction. Confirmation of this complication by ultrasonography provides important information about increased risk of future systemic embolic events.

We present a case of intrapancreatic accessory splenic infarction in a 28-year-old woman. It was discovered during a workup for an acute right epigastric pain. Computed tomography imaging of abdomen demonstrated a hemorrhagic high attenuation with enhancing solid portion in the tail of pancreas. The clinical and radiological differential diagnosis included pancreatic mucinous cystic neoplasm, pancreatic endocrine neoplasm, solid pseudopapillary tumor, ductal adenocarcinoma, and metastasis. A distal pancreatectomy was completed. The microscopic examination revealed heterotopic splenic tissue with infarction and her abdominal pain disappeared. In this case report, we first describe a symptomatic accessory splenic infarction which presented as a hemorrhagic mass in the tail of pancreas mimicking pancreatic neoplasm.
