The case of a 77-year-old male patient who complained of left upper quadrant pain and progressive vomiting. Laboratory examination showed extremely high lactic acid dehydrogenase (LDH) and adult T-cell leukemia antibody (ATLA). The anatomical studies CT, MRI, US and upper GI series substantiated an omental lymphadenopathy which was causing a circumferential compression of portions of the duodenum and jejunum. Gallium-67 citrate (Ga-67) scintigraphy showed high uptake at LUQ. Ultrasound guided biopsy failed to confirm the diagnosis. Irradiation was performed. Ga-67 scintigraphy had a contributory role in clinical subtyping of the disease, planning of treatment, posttreatment assessment and prognostication of adult T-cell lymphoma.

Splenic abscess is a rare clinical entity but may be underreported. A retrospective study at Srinagarind Hospital revealed 60 cases of splenic abscess between 1992 and 2001. The causative organisms were identified in 41 cases (68.3%). Gram negative bacilli were commonly isolated and Burkholderia pseudomallei was the most predominant. Diabetes mellitus and leukemia were common underlying diseases found in 46.3 per cent and 9.7 per cent of culture confirmed cases, respectively. The patients usually presented with fever, left upper quadrant pain, tenderness and splenomegaly. Multiple abscesses were more commonly found in the melioidosis than in the non-melioidosis group (p = 0.032), but a single abscess was more commonly found in the non-melioidosis than in the melioidosis group (p = 0.032). Concurrent liver abscesses, often multiple, were not different in both groups. Antimicrobials alone were given in 66.7 per cent of cases with melioidosis and 64.7 per cent of non-melioidosis group. Splenectomy and percutaneous aspiration were performed only in 29.3 per cent and 4.9 per cent of cases with splenic abscess. The overall mortality rate of splenic abscess was only 4.9 per cent in the present series. In conclusion, splenic abscess is not uncommon. Burkholderia pseudomalleli is the most common causative agent found in the present series. Therefore, it should be targeted in the initial empirical antibiotic therapy before the culture results are available especially when multiple lesions in the spleen and concurrent multiple liver abscesses are seen. Prolonged treatment with appropriate antimicrobials alone is usually effective. Splenectomy and/or aspiration may be useful in selected patients.

A 42-year-old white woman, who was a general practitioner referral to the medical team, presented with a 3-day history of left upper quadrant pain; an urgent private ultrasound scan had showed splenomegaly. She was initially admitted with sepsis without an obvious cause but with a differential diagnosis of a haematological malignancy. Her admission blood tests showed a mildly reduced white cell count and low platelets. Her symptoms progressed and she developed right upper quadrant pain. Her blood counts deteriorated showing a disseminated intravascular coagulation (DIC) picture and mildly deranged liver function tests. Blood films were non-diagnostic. A CT scan of the abdomen/pelvis showed splenomegaly and also hepatomegaly and ascites, not seen in her initial ultrasound scan. Multiple cultures of blood/urine/ascites and infective serology were unremarkable.She was transferred to a larger tertiary centre under the care of the surgeons with presumed abdominal sepsis and underwent an open laparotomy, which showed a big firm liver and spleen but no obvious cause for sepsis. The infectious disease team were unable to find a cause, and haematology became involved to investigate the possibility of a haematological malignancy. The patient underwent two bone marrow biopsies, a percutaneous liver biopsy and had flow cytometry of her ascitic fluid, which revealed the diagnosis of a natural killer cell leukaemia. After some slight improvement on steroids, the patient was given cyclophosphamide, doxorubicin, vincristine, prednisone, rituximab (CHOP-R) chemotherapy. The patient had an initial response to chemotherapy, with reduction in ascitic volume and hepatosplenomegaly, and normalisation of her coagulation. This was accompanied by an overall improvement in her physical condition. She had a second cycle of CHOP-R, but unfortunately approximately 2 weeks after that, she deteriorated rapidly. She was too weak for salvage chemotherapy, so she was put on comfort care. She died peacefully.
