spleen leukemia ultrasound

AIM OF THE STUDY: Spontaneous splenic rupture is a serious complication of pathologically altered spleen tissue, associated with a high mortality rate. CASE DESCRIPTION: We describe a spontaneous splenic rupture in a patient with acute lymphoblastic leukemia undergoing chemotherapy. Ultrasound revealed splenomegaly, and diffuse splenic acute lymphoblastic leukemia-infiltration was suspected. In addition, only color Doppler sonography and contrast-enhanced ultrasound diagnosed splenic vascular ectasias with a venous-flow-profile...

OBJECTIVE: A hypo-enhancement of the liver in contrast-enhanced ultrasound (CEUS), pathologic one-minute hepatic enhancement (pOMHE), was recently observed in 70% of allogeneic hematopoietic stem cell transplantation patients with a high-risk profile for veno-occlusive disease (VOD). Whether pOMHE was a pre-clinical sign of VOD or an unspecific feature of liver damage secondary to intensive chemotherapy is unclear. METHODS: To investigate this, we studied CEUS patterns in patients receiving high-dose chemotherapy prior to autologous hematopoietic stem cell transplantation (auto-HSCT) or intensive induction therapy (IT) for the treatment of acute leukemia...

BACKGROUND: Down syndrome myeloid hyperplasia includes transient abnormal myelopoiesis (TAM) and the myeloid leukemia associated with Down syndrome (ML-DS). The mutation of GATA1 gene is essential in the development of Down syndrome combined with TAM or ML-DS. Some patients with TAM are asymptomatic and may also present with severe manifestations such as hepatosplenomegaly and hydrops. CASE PRESENTATION: We report two cases of prenatally diagnosed TAM. One case was a rare placental low percentage 21 trisomy mosiacism, resulting in the occurrence of a false negative NIPT...

A fixed duration of venetoclax-rituximab (VenR) resulted in a significant benefit of both PFS and in the attainment of an undetectable minimal residual disease (uMRD) compared with bendamustine-rituximab in relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL) patients. The 2018 International Workshop on CLL guidelines, outside the context of clinical trials, suggested ultrasonography (US) as a possible imaging technique to evaluate visceral involvement, and palpation to evaluate superficial lymph nodes (SupLNs)...

Objectives: The kidney is a vulnerable organ for acute lymphoblastic leukemia (ALL), by the disease, and various associated clinical pictures. This retrospective study aims to document renal ultrasound abnormalities in children with newly diagnosed ALL as well as to investigate the correlation between renal findings and clinical/laboratory/survival data. Methods: All children (age <18 years) with ALL were included in the study. An increase in size/nephromegaly (NM) or hyperechogenicity (HE) of the kidneys at first admission was accepted as a pathological renal abnormality...

BACKGROUND: Liver involvement in adults with acute myeloid leukemia is uncommon. Most of the case reports describe acute liver failure or obstructive jaundice, while acute hepatitis is rarely mentioned. We report a patient with acute myeloid leukemia who presented with clinical, biochemical, and radiological signs of acute hepatitis that totally regressed after chemotherapy. CASE PRESENTATION: A 38-year-old Caucasian man presented with fever, cough, and mild fatigue...

OBJECTIVE: To report the management and outcomes of two pigs undergoing emergency surgery for hemoabdomen secondary to splenic disease. STUDY DESIGN: Case report. ANIMAL: Two adult pigs with hemoabdomen and suspected splenic pathology. METHODS: Pigs were admitted for several clinical signs including lethargy, inappetence, vomiting, abdominal distention, hypothermia, and tachycardia. Abdominal ultrasound and abdominocentesis led to a diagnosis of hemoabdomen secondary to splenic disease...

BACKGROUND: In IWCLL guidelines, progressive splenomegaly and lymphadenopathy are signs of active disease. In this study, we have tested the hypotheses if US could be a reliable tool for both superficial lymphnodes (SupLNs) and splenic assessment in chronic lymphocytic leukemia (CLL) patients. METHODS: We enrolled N = 75 patients. SupLN and the spleen were assessed by two independent physicians (M1 and M2) by palpation and by a third physician (M3) with ultrasound sonography (US) using two different sonographers (US1 and US2)...

Extramedullary hematopoiesis (EH) refers to hemopoiesis that occurs outside of the bone marrow and can be physiologic or pathologic in nature. Common sites of EH include the liver, spleen, and paravertebral soft tissues. Less commonly, EH can occur in the kidneys, pleura, paranasal sinuses, and various other organs. In this report, we describe two cases of EH with abnormal presentations on imaging. The first case discusses a 72-year-old female with a history of chronic myelogenous leukemia complicated by myelofibrosis...

Background: Focal splenic lesions are usually incidentally discovered on radiological assessments. Although percutaneous tissue acquisition (TA) under trans-abdominal ultrasound guidance is a well-established technique for obtaining cyto-histological diagnosis of focal splenic lesions, endoscopic ultrasound (EUS)-guided TA has been described in several studies, reporting different safety and outcomes. The aim was to assess the pooled safety, adequacy, and accuracy of EUS-TA of splenic lesions...

Spontaneous splenic rupture (SSR) is a rare life-threatening emergency. In hematological settings, it is uncommon in acute myeloid leukemia (AML). We report an atypical case of SSR in a 73-year-old male with AML where a prompt imaging ultrasound assessment played a key role. Performed noninvasively at bedside, it allowed rapid imaging diagnosis, confirming its essential role even in the presence of hematological disease.

Standard therapy in hairy cell leukemia (HCL) is often impossible at the time of deep neutropenia/agranulocytosis with or without infectious complications; it is thus a complex therapeutic problem. Vemurafenib has been used to treat resistant HCL since 2012. Because vemurafenib does not have a myelotoxic effect, we thought that it could be used to treat HCL associated with deep neutropenia/agranulocytosis with or without the development of infectious complications as a preliminary stage before treatment with cladribine...

INTRODUCTION: Spontaneous splenic rupture is an atraumatic event that represents a rare and life-threatening acute complication in which the spleen is damaged producing internal hemorrhage in the abdominal cavity. Its association with hematologic malignancies, although a rare occurrence, has been previously described. Among this subset of patients, chronic myeloid leukemia is one of the main causes. PRESENTATION OF CASE: A 26-year-old male with history of chronic myeloid leukemia presented with acute intense abdominal right lower quadrant pain...

Pseudoaneurysm (PSA) or false aneurysm is a vascular lesion resulting from a focal and incomplete rupture of the arterial wall (intimate and/or elastic lamina), that allows blood to escape into the arterial wall; this small contained break causes a contained collection of blood and the creation of a "new" less resistant vessel wall, consisting of adventitia and perivascular tissues. Intrasplenic pseudoaneurysms are rare and more frequently recognize traumatic origin, sometimes are also unexpected lesions due to non-recent trauma...

RATIONALE: Granulocyte colony-stimulating factor (G-CSF) is most frequently used in healthy donors to mobilize progenitor cells into the peripheral blood for collection. While mild thrombocytopenia is common in allogeneic peripheral blood stem cell transplant donors after G-CSF mobilization, serious thrombocytopenia is rarely reported. Herein, we report a case of severe thrombocytopenia caused by G-CSF in a 14-year-old healthy donor and review the relevant literature. To our knowledge, this is the first reported case of severe thrombocytopenia caused by G-CSF in a healthy adolescent donor...

An asymptomatic 14-year old, male black swan ( Cygnus atratus ) housed at a zoological institution was presented for routine preshipment examination. Hematologic findings indicated that the bird had a severe lymphocytic leukocytosis, consistent with chronic lymphocytic leukemia. Radiographs showed the presence of multiple soft tissue masses within the caudal coelomic cavity; ultrasound showed one mass to be an enlarged spleen, a cystic mass near the gonads, and a mass suspected to be associated with the ventriculus...

BACKGROUND: Children with leukemia often have hepatosplenomegaly present. This can be diagnosed with physical examination and confirmed with ultrasound. We sought to determine if level of training influenced the ability to detect hepatosplenomegaly. METHODS: All children diagnosed with leukemia during the past 5 years were reviewed. The training level of the examiner, the documentation of hepatosplenomegaly, and the ultrasound findings were collected and analyzed...

A 64-year-old man with a history of chronic lymphocytic leukemia (CLL) presented in the hematology department due to remarkable leukocytosis and progressing anemia. Ultrasound confirmed splenomegaly and plain computed tomography revealed multiple hypoattenuating areas in the large spleen. Following a clinical diagnosis of relapse of CLL, he underwent treatment with fludarabine, cyclophosphamide, and rituximab (FC-R). After five cycles of FC-R treatment, his leukocyte count and hemoglobin level were normalized, and the size of the spleen also decreased...

We report a case of a 47-year-old man who firstly complained of throat pain for half a month accompanied with fever. Specialized examination showed tonsils' hypertrophy and the laryngoscope found his right vocal cord was swelling and hyperemia. The routine blood test counted white blood cell as 31 x 10(9)/L, lymphocyte as 30. 84 x 10(9)/L while prolymphocyte could be seen with microscope. After that B-ultrasound scan gave spleen hypertrophy and multi-lymphatic-node enlargement. Peripheral blood flowcytometry and bone marrow biopsy finally diagnosed the man as actue myelocytic leukemia...
