    We report a case of a previously healthy 38-year old lady who presented with prolonged fever and hepatosplenomegaly. Intensive investigations were performed for pyrexia of unknown origin which revealed negative. CT scan of the abdomen showed multiple hypodense lesions which did not respond to broad-spectrum antibiotics. Percutaneous biopsy of the splenic lesion revealed granuloma formation and Langhan's giant cells suggestive of TB. She responded well with anti- TB medication but required extended treatment duration of 24 months due to persistence of the splenic lesion on repeated CT scans. This case illustrates a very rare clinical entity of isolated splenic TB with a therapeutic dilemma following incomplete resolution, despite prolonged treatment.

    A 30-year-old female entered the emergency room for medical advice because of progressive deterioration of general health with headache, arthralgias, myalgias and fever after a vacation of three weeks in Malaysia and Hong Kong. Because of persistent fever, lymphadenopathy, slight leuco- and thrombocytopenia and only insignificantly elevated humoral signs of an inflammatory process, the patient was treated symptomatically after exclusion of malaria. A viral disease was suspected. Two days later, an exanthema erupted suddenly on the trunk. Pinhead-sized livid, flat macules, increasing in size within hours and spreading to the extremities, were observed. Further investigations revealed a significantly elevated titer of IgG directed against rickettsia conorii, leading to the diagnosis of Mediterranean spotted fever. Under antibiotic treatment with tetracycline, the aforementioned findings regressed within few days, and the patient recovered completely.

    A 35-year-old man from Bangladesh, who had been in Malaysia for approximately a year, was extensively investigated for more than two months in a state hospital for pyrexia with hepatosplenomegaly. However, no obvious cause of his illness was found. He was treated with multiple antibiotics with no resolution of pyrexia and hepatosplenomegaly. He was later referred to the Haematology Unit, Universiti Kebangsaan Malaysia for further assessment as a case of lymphoma. On carefully reviewing his bone marrow aspirate smears, the diagnosis of leishmaniasis (kala-azar) was finally made. The patient responded to treatment with pentamidine.

    INTRODUCTION: There is an awareness of the increased incidence of splenic abscess in Southeast Asia giving rise to unexplained fever. This study looks at the role of computed tomography (CT) in evaluating focal splenic lesions in patients presenting with fever.
    METHODS: 37 patients presenting with fever of unknown origin underwent CT and this study retrospectively analyses the findings in these patients. 13 patients also had associated abdominal pain. Patients with conditions at high risk for splenic infection include: diabetes mellitus in ten patients, leukaemia in seven patients, human immunodeficiency virus infection in five patients, intravenous drug abuse in six patients, and steroid therapy in two patients. No risk factors could be identified in seven patients.
    RESULTS: Splenic abscess was diagnosed in 28 patients. A range of infecting organisms was isolated but the most frequent were Staphylococcus aureus (eight), tuberculosis (four), Streptococcus (four), fungal (four) and melioidosis (four). No infecting organism could be identified in ten cases though in patients with leukaemia with multiple low attenuation areas, the cause was presumed to be fungal. Six patients were diagnosed to have splenic infarcts though differentiation from splenic abscess could be difficult; these patients were treated for an abscess and all had endocarditis. Three patients were subsequently diagnosed with lymphoma. Percutaneous abscess drainage was performed in five patients and splenectomy was carried out in six patients.
    CONCLUSION: CT proved to be very useful as it not only revealed the size and extent of any splenic abnormality but it assisted with guidance for percutaneous drainage, determined the site for biopsy, and provided follow-up after treatment.

    We studied 1,629 febrile patients from a rural area of Malaysia, and made a laboratory diagnosis in 1,025 (62.9%) cases. Scrub typhus was the most frequent diagnosis (19.3% of all illnesses) followed by typhoid and paratyphoid (7.4%); flavivirus infection (7.0%); leptospirosis (6.8%); and malaria (6.2%). The hospital mortality was very low (0.5% of all febrile patients). The high prevalence of scrub typhus in oil palm laborers (46.8% of all febrile illnesses in that group) was confirmed. In rural Malaysia, therapy with chloramphenicol or a tetracycline would be appropriate for undiagnosed patients in whom malaria has been excluded. Failure to respond to tetracycline within 48 hours would usually suggest a diagnosis of typhoid, and indicate the need for a change in therapy.

    Since 2011, about 100 travellers to the island of Tioman, Malaysia, have been diagnosed worldwide with suspected muscular sarcocystosis, a previously only sporadically observed parasitic disease. Source of infection and therapy remain unclear. Final diagnosis requires microscopic identification of cysts in muscle biopsies. The study objective was a systematic description of characteristic symptoms, laboratory investigations and treatment response.

    Pyrexia of unknown origin (PUO) is a frequent presentation to the Acute Medical Unit, and is a source of significant morbidity, both the psychological burden of an uncertain diagnosis and prognosis and untreated complications of the underlying pathology. We present a problem based review of the management of PUO, illustrated by a patient who recently presented to our unit with fever and systemic malaise after returning from abroad and in whom no cause could be found for more than two months. We describe a structured approach making use of complex modern techniques such as Positron Emission Tomography-Computed Tomography (PET-CT) which ultimately provided the diagnosis for our patient.
