Ultra-Small Lung Cysts Impair Diffusion Without Obstructing Air Flow in Lymphangioleiomyomatosis.

Chest 2021 Feb 5. Epub 2021 Feb 5.

National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, MD. Electronic address:

Background: Lymphangioleiomyomatosis (LAM) is a rare lung disease found primarily in women of childbearing age, characterized by the formation of air-filled cysts, which may be associated with reductions in lung function. An experimental, regional ultra-high resolution CT scan identified an additional volume of cysts relative to standard chest CT imaging, which consisted primarily of ultra-small cysts.

Research Question: What is the impact of these ultra-small cysts on the pulmonary function of patients with LAM?

Study Design And Methods: A group of 103 patients with LAM received pulmonary function tests and a CT examination in the same visit. Read More

Effect of everolimus on multifocal micronodular pneumocyte hyperplasia in tuberous sclerosis complex.

Respir Med Case Rep 2020 25;31:101310. Epub 2020 Nov 25.

Department of Respiratory Medicine, Lausanne University Hospital (CHUV) and University of Lausanne, Switzerland.

Multifocal micronodular pneumocyte hyperplasia (MMPH) is a benign proliferation of alveolar type II cells presenting as multiple pulmonary nodules at chest imaging, which is frequently seen in patients with tuberous sclerosis complex (TSC). We report a case of a woman with TSC and MMPH who received everolimus, a mechanistic target of rapamycin (mTOR) inhibitor, for the treatment of a subependymal giant cell astrocytoma (SEGA). After 3 months of therapy, a remarkable decrease in density of all pulmonary MMPH lesions was observed, without any change in size. Read More

Pulmonary lymphangioleiomyomatosis masquerading as unilateral heterogeneous emphysema.

J Surg Case Rep 2020 Nov 30;2020(11):rjaa486. Epub 2020 Nov 30.

Department of Cardiothoracic Surgery, Royal Stoke University Hospital, Stoke On Trent, UK.

Pulmonary lymphangioleiomyomatosis (LAM) is a rare, well-described pathology and usually is exclusive to females of a reproductive age. We present a 45 year-old lady who presented to the surgeons 1 year after an admission with acute dyspnoea following influenza infection. Initial computed tomography imaging findings demonstrated severe, heterogenous right-sided bullous emphysematous changes, but histopathological analysis of the post-operative specimen favoured a diagnosis of LAM.

Diagnostic usefulness of transbronchial lung cryobiopsy in two patients mildly affected with pulmonary lymphangioleiomyomatosis.

Respir Investig 2020 Jul 4;58(4):295-299. Epub 2020 Apr 4.

Department of Respiratory Medicine, Japanese Red Cross Medical Center, 4-1-22 Hiroo, Shibuya-ku, Tokyo, 150-8935, Japan. Electronic address:

Transbronchial lung biopsy is a non-invasive technique used primarily for the pathological diagnosis of lymphangioleiomyomatosis (LAM). However, some cases, particularly those with early-stage lung lesions, are difficult to diagnose because of the specimen size and presence of artifacts. Herein, we present two cases of LAM with relatively mild cystic changes in the lungs and slight impairment seen in pulmonary function tests. Read More

Division of Pulmonary, Critical Care and Sleep Medicine, Westchester Medical Center, Valhalla, NY.

Cystic lung disease encompasses a wide variety of clinical entities, the diagnosis of which is sometimes straightforward and other times obscure.  To narrow the list of possibilities, it behooves the physician to consider the context in which the cystic lung disease is uncovered. Clues to the diagnosis might be provided by findings that are not initially obvious and are not located in the thorax. Read More
