Ganglioneuroblastoma is a tumor of the sympathetic nervous system in paediatric age group that is intermediate in behavior between ganglioneuroma and neuroblastoma. We present a case of a 3 year old girl who presented with a large long standing abdominal mass. Ultrasonographic features were suggestive of large retroperitoneal mass with calcific foci & extensive vascular encasement consistent with neurogenic tumor. Contrast enhanced computed tomography (CT) performed for staging confirmed these findings while histopathologic diagnosis of ganglioneuroblastoma was achieved by ultrasound guided biopsy. While vascular encasement is known in ganglioneuroblastoma, the scale of vascular encasement in this case is extensive.

The study was aimed at evaluating role of CT Pulmonary Angiography (CTPA) and Indirect CT venography (ICTV) in clinically suspected pulmonary embolism (PE) in oncology setup.17/31 (54.9%) patients were diagnosed with PE with or without deep vein thrombosis. DVT was diagnosed in 12(38.7%). 1 patient had DVT in absence of PE while 13/31 (41.9%) patients were diagnosed not to have PE or DVT. Clinical symptoms or pre-test probability determined by Well’s criteria and other laboratory investigations were not found predictive of PE. CTPA diagnosed PE with greater ease, shorter time required with no dependence on clinical pretest probability unlike pulmonary scintigraphy. In cases with CTPA negative for PE, CT described additional findings possibly explaining patient’s presenting symptoms unlike negative pulmonary scintigraphy. In cases where PE was excluded, CTV identified DVT (if present) in the same sitting, obviating separate venous Doppler. A single investigation with ability to deal with complete spectrum of DVT and PE makes CTPA & ICTV ‘one stop shop’ imaging modality for PE and DVT.
