Ectopic extralobar pulmonary sequestrations in children: interest of the laparoscopic approach.

Background: Extralobar pulmonary sequestrations (EPS) are a rare benign congenital bronchopulmonary foregut malformation. Complete resection is necessary to confirm the diagnosis with histopathologic examination. The aim of this study was to describe the laparoscopic minimally invasive surgery (MIS) for a small series of ectopic EPS in small children and to show its feasibility and safety.

Computer tomography in pulmonary invasive aspergillosis in hematological patients with neutropenia: an useful tool for diagnosis and assessment of outcome in clinical trials.

Background And Objective: The exact timing of the evolution of lesion volumes of invasive pulmonary aspergillosis (IPA) on CT scan images could be helpful in the management of hematological patients but has never been evaluated in a prospective study. We analyzed the CT scan data from the prospective Combistrat trial.

Design And Methods: Volumes of aspergillosis lesions from 30 patients (including 24 acute myeloid leukaemia) with probable (n=26) or proven (n=4) IPA according to the EORTC-MSG modified criteria, were measured prospectively on the thoracic CT scans at the enrolment in the study on day 0 (D0), D7, D14 and end of treatment (EOT).

[Nasopharyngeal tonsillolith: a report of 31 cases].

Objective: Nasopharyngeal tonsilloliths are less well known to radiologists than palatine tonsil lithiases. The possibility of routinely available fine slices during CT scans of the head and neck prompted a retrospective study on the causes and radiological signs and patterns of nasopharyngeal tonsilloliths.

Material And Methods: A total of 515 CT scans were retrospectively re-examined looking for calcifications of the posterior wall of the nasopharynx.
