Leucomyelitis was the predominant feature in four North American adult sheep (cases 1-4) with ovine lentivirus (OvLV) infection. All four animals were OvLV-seropositive and a syncytogenic virus consistent with OvLV was isolated from the brain of case 3 and the lungs of case 4. Clinically, the sheep had dyspnoea and neurologic signs of varying severity. Changes in the central nervous system included asymmetrical meningoleucomyelitis with white matter degeneration in all four sheep and scattered foci of leucoencephalitis in periventricular, subependymal and other white matter areas of the brain of the three animals (cases 1, 2 and 4) for which the brain was examined. In the lungs of two sheep (cases 3 and 4), there was lymphoid interstitial pneumonia with marked lymphoid hyperplasia. The viral capsid antigen (p25) was detected by immunohistochemistry (IHC) in sections of lung, brain and spinal cord of the four sheep and OvLV RNA was detected by in-situ hybridization (ISH) in lung and spinal cord samples. The results confirm the usefulness of the IHC and ISH for differential diagnosis of visna.

Hypersensitivity pneumonitis (HP) is an interstitial lung disease caused by the inhalation of organic substances and certain inorganic chemicals. The histopathologic features of chronic HP (CHP) have not been studied extensively. We examined the pathologic characteristics of 16 autopsy cases of clinically confirmed CHP and compared them with 11 cases of idiopathic pulmonary fibrosis/usual interstitial pneumonia (IPF/UIP). To clarify the exact intralobular location of the fibrotic lesions, we conducted 3-dimensional reconstruction of fibrosis of CHP and IPF/UIP. Granuloma was not detected in any CHP case. Similar to IPF/UIP, honeycombing lesions were found dominantly in the lower lobes in most CHP cases; upper lobe dominance and asymmetrical distribution of honeycomb lesions were more frequent in CHP than in IPF/UIP. In all lungs affected by CHP, centrilobular fibrosis was outstanding, often connecting to the perilobular areas in the appearance of "bridging fibrosis," which was clearly demonstrated by 3-dimensional imaging. Centrilobular and bridging fibrosis were significantly more conspicuous in CHP than IPF/UIP; however, considerable overlap was found. It is important to thoroughly explore the possibility of antigen exposure in cases of lungs with UIP with centrilobular fibrosis to discriminate CHP from IPF/UIP.

We herein report a case of asymmetrical interstitial lung disease (ILD) that remained almost completely asymmetrical over time on chest computed tomography (CT). An open lung biopsy from the right lung showed severe pleural adhesion, obstruction of the pulmonary artery, and dilated systemic arteries in addition to the usual interstitial pneumonia pattern. Three-dimensional CT angiography showed partial defects of pulmonary arteries on the affected side. After excluding other known causes of ILD and gastroesophageal reflux, we suspected that decreased pulmonary artery perfusion in the present case may have been responsible for the observed asymmetrical unilateral fibrosis.
