Pneumothorax after CT guided transthoracic needle aspiration biopsy of lung masses

The purpose of this study was to analyze the rate of pneumothorax after CT guided transthoracic needle aspiration biopsy [TNAB] of lung masses, using variable needle sizes. A total of 70 patients underwent this procedure, among them, 18 patients [26%] developed pneumothorax with 18G needles 24 patients underwent FNA and seven of them [25%] developed pneumothorax, with 20G needle, 26% developed pneumothorax and with the 22G needle 25% developed Pneumothorax. As a conclusion the study shows that the rate of pneumothorax after CT guided TNAB of lung masses remains almost the same regardless of the size of the needle

Intracranial menifestations of tuberculosis: an imaging study

In this paper we report various intracranial manifestations of tuberculosis in 48 patients who presented at our hospitals. The object of this study was to see different patterns of intracranial tuberculosis seen on cross sectional imaging in the city of Lahore and its suburbs. In a total of 48 patients, 21 had meningitis, 16 patients were found to have tuberculomas which also included 6 who had accompanying meningitis. Vasculitis resulting in lacunar infarcts was seen in 3 patients. Hydrocephalus was seen in 5 patients and choroid plexus tuberculosis [choroid plexitis] was seen in 3. Intracranial tuberculosis, therefore can have many presentations such as meningitis, tuberculomas or rare varieties such as abscess, cerebritis or choroid plexus involvement. It can also lead to devastating complications such as hydrocephalus and infarcts
