Low-attenuation consolidation — the most characteristic finding in lipoid pneumonia

Vaping Associated Pulmonary Injury (VAPI) is a group of respiratory symptoms like shortness of breath and tachypnea and, oftentimes, it is associated with non-specific symptoms like generalized fatigue, body ache, fever, nausea, diarrhea, vomiting and chills. This entity has been previously categorized as a diagnosis of exclusion and best described as an exogenous lipoid pneumonia, or chemical pneumonitis. Exogenous lipoid pneumonia has characteristic finding in histology where inhaled fatty substances are recognized with special stain versus endogenous lipoid pneumonia, which is due to airway obstruction giving histology look of cholesterol crystals and accumulated debris. Here we describe the onset of an exogenous cause of lipoid pneumonia in an otherwise healthy patient using cannabis-containing products. We explore, similarities in the clinical case, identify common clinical features, characteristic radiologic findings along with cytological changes in the lungs.

The Right

This case report describes a simple hemorrhage (SH) presenting as radial hemorrhage in Henle’s fiber layer (HFL) in a patient with high myopia. A 26-year-old girl with high myopia was referred to our center for sudden onset of decreased vision and a central scotoma in the right eye (OD). Best corrected visual acuity (BCVA) was 20/100 OD. Fundus examination showed a stellate intraretinal hemorrhage in the fovea of the OD. The hemorrhage was organized in a peculiar petaloid pattern with feathery distal edges, suggesting localization within the radially oriented HFL. The presence of both choroidal neovascularization and microvascular abnormalities consistent with macular telangiectasia type 2 (MacTel 2) were excluded. Based on these findings, a diagnosis of myopic SH was made. At 4-month follow-up BCVA OD spontaneously improved to 20/40, without any treatment been ever administered to the patient. Spectral-domain optical coherence tomography OD showed reabsorption of the hemorrhage and almost complete restoration of the foveal architecture. The intraretinal location and spread of the hemorrhage into the HFL in our patient are an unusual presentation of SH, which vividly highlights the anatomy of the fovea. Since fibers in HFL are quite delicate and loosely arranged, this layer is very susceptible to deposition of transudates, exudates, hemorrhage, and other products. Radial hemorrhage in HFL has been originally reported in 4 patients as complication of MacTel 2. It has been previously postulated that it may represent a characteristic finding in MacTel 2 that may develop as a result of microvascular abnormalities of the deep retinal capillary plexus. On the contrary, our data suggest that radial hemorrhage in the HFL does not represent a characteristic finding of MacTel 2, but must rather be considered a non-specific sign with multiple possible etiologies.

White Substance

A 75-year-old woman had a 5 mm slightly elevated yellowish lesion in her thoracic esophagus. Narrow-band imaging magnifying endoscopy (NBI-ME) revealed aggregations of a tiny white substance beneath each intrapapillary capillary loop with weaving, dilatation, and a different shape. In this case, an irregular caliber was absent. The biopsy specimen taken from the lesion showed cells with large nuclei and increased chromatin clumping in the basal layer. These cells were positive for p53. Endoscopic submucosal dissection was performed for the purpose of excisional biopsy. Finally, it was diagnosed as an esophageal xanthoma with a benign epithelial reactive inflammation. This is the first report of esophageal xanthoma showing the characteristic NBI-ME finding of esophageal xanthoma. Further studies are required to determine whether the characteristic finding of NBI-ME is generally found in esophageal xanthomas.
