Hot liver on 18F-FDG PET/CT imaging-a quandary for oncoradiologists in South Asia.

A 56-year-old female presented with intermittent hemoptysis and was diagnosed with lung cancer. F-fluorodeoxyglucose positron emission tomography/CT for staging revealed hypermetabolic liver (hot liver), uptake in the mediastinal lymph nodes and reduced uptake in the kidneys. Unexpectedly, liver biopsy findings were consistent with tuberculous infection.

CT density of cervical thymus, in comparison with mediastinal thymus.

Objectives: Cervical component of thymus is noted more in children and young adults than in older age group. CT texture (lobules of soft tissue interspersed with fat), similarity with CT density of mediastinal thymus and continuity with mediastinal thymus on sagittal/coronal images, are given as the criteria for diagnosis of the cervical thymus. But CT densities of cervical and mediastinal components of the thymus may vary.

Wolman Disease: A Mimic of Infant Leukemia.

Background: Infant leukemia most commonly present with pallor and hepatosplenomegaly. The possibility of other differential diagnosis also has to be kept in mind during evaluation, as identifying the precise etiology for this clinical presentation is crucial for management.

Observation: An infant, was referred to us with suspected infant leukemia and was subsequently diagnosed to have lysosomal acid lipase deficiency/Wolman disease with a novel 5 bp deletion "c.
