“…There were 16 male and 23 female cases, while the age and gender were not indicated in 2 cases [ 9 , 12 ]. Ages ranged from 32 to 85 years and, consistent with previous findings [ 17 , 18 , 24 ], the average age of the patients was in the sixth decade (64 years).…”

18F-FDG PET/CT in Patients with Nodular Pulmonary Amyloidosis: Case Report and Literature Review

et al. 2014

A 62-year-old woman was found to have multiple bilateral pulmonary nodules showing different ¹⁸F-fluorodeoxyglucose (FDG) uptakes on positron-emission tomography/computed tomography (PET/CT). Only the largest nodule in the left lower lobe showed an increased ¹⁸F-FDG uptake on PET/CT. Three nodules were surgically resected from different lobes of the left lung. Two lobes were benign and showed amyloid deposition. The largest nodule in the left lower lobe showed adenocarcinoma and a heavy amyloid deposition. Pulmonary amyloidosis should be added to the differential diagnosis for cases with multiple pulmonary nodules that show different ¹⁸F-FDG uptakes on PET/CT. To the best of our knowledge, this is the second reported case of a lung nodule consisting of adenocarcinoma and amyloid deposition.

“…When nodular appearance is localised on chest CT scan, it usually raises the suspicion for primary or metastatic lung malignancy 17. Although our patient had SLE, it is very rare to see this chronic, inflammatory, autoimmune condition associated with pulmonary amyloidosis.…”

Pulmonary amyloidosis is a rare disease that incorporates deposition of amyloid microfibril material in the lung parenchyma. The condition generally presents as an indolent subacute-to-chronic pulmonary disease and requires tissue biopsy to establish the diagnosis. Nodular pulmonary amyloidosis, a subtype of pulmonary amyloidosis, is characterised by special radiographic and pathological features. While the disease can be associated with inflammatory conditions; its association with mucosal-associated lymphoid tissue (MALT lymphoma) is unusual and carries management challenges. Herein, we illustrate a case study of nodular pulmonary amyloidosis associated with underlying MALT lymphoma in a patient with known systemic lupus erythematosus. The aim of this article is to share the management experience of this complex condition with the medical community and to conduct an up-to-date literature review on nodular pulmonary amyloidosis.

“…It was pointed out that despite the lower sensitivity and specificity, a maximum standardized uptake value (SUVmax) of >3 should still prompt consideration for an underlying lymphoproliferative neoplasm. 24 In another study, 11 out of 42 cases with lung MALT lymphoma were positive on PET scan. 25 Similar results were seen in a second study where 8 of 26 cases with lung MALT lymphoma were PET avid.…”

Amyloidosis is the term given to abnormal deposition of misfolded precursor proteins at single or multiple sites, leading to organ dysfunction or clinical signs and symptoms. Pulmonary manifestations are nonspecific and may be associated with several amyloid protein subtypes, commonly AL (light chain) and AA (autoimmune) amyloids. Signs or symptoms of amyloid disease may often involve more of the clinical abnormalities of other affected organs than the lungs themselves. Radiologic pulmonary findings include septal and parenchymal ground glass or nodular infiltrates, multiple nodules, cysts, and focal tracheobronchial abnormalities. Lymphadenopathy with or without calcification and pleural effusions has also been reported. Directed therapy is initiated in response to clinical signs or symptoms often as a result of systemic or secondary diseases or conditions. Long-term prognosis is more dependent on the extent of organ involvement where morbidity is often the highest in those with multisystemic disease.
