Endobronchial and endoscopic ultrasound: it only takes an echobronchoscope to tango
Chun Ian Soo, Sze Shyang Kho, Boon Hau Ng, Siew Teck Tie DOI: 10.1002/rcr2.482
In this case series, we describe three cases of lung malignancy diagnosed using three distinct applications of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound with bronchoscope-guided fine-needle aspiration (EUS-B-FNA). Both procedures can be performed in a single session and by a single operator; this translates into an overall reduction in the healthcare cost. When EBUS-TBNA and EUS-B-FNA are combined, the technique allows for the augmentation of diagnostic potentials and increased precision in staging procedures. |

Rare growth pattern of a solitary cystic lung metastasis from colon cancer: a case report
Keisuke Eguchi, Takahiro Nakajima, Takeshi Terashima, Aya Sasaki, Hirotoshi Hasegawa, Junichi Matsui DOI: 10.1002/rcr2.474
We report a surgical case of a solitary pulmonary metastasis in which the lesion grew from a cyst into a nodular lesion within the cyst with time. |
Erdheim-Chester disease progression from miliary pulmonary nodules to large tumours
Jun Shiihara, Hiromitsu Ohta, Satoshi Ikeda, Tomohisa Baba, Koji Okudera, Takashi Ogura DOI: 10.1002/rcr2.475
A 66-year-old man with Erdheim-Chester disease who presented at first visit with randomly distributed multiple pulmonary nodules and who then developed large tumour shadows. To our knowledge, this random distribution pattern of multiple pulmonary nodules has not previously been reported. |
Acute saddle pulmonary embolism on 18F-FDG PET/CT: diagnosis by functional imaging
Dalveer Singh, Roslyn Foessel, Navjot Nagra, Pauline Lau, Damian Brauchli DOI: 10.1002/rcr2.476
First description in the literature of incidental saddle pulmonary embolus diagnosed on 18F-labelled fluoro-2-deoxyglucose positron emission tomography/computed tomography by seeing pulmonary infarction and right-sided myocardial uptake. This will alert clinicians about the importance of these signs and direct emergent of further investigation and therapy. |
Impressive response to nivolumab of non-small-cell lung cancer containing sarcomatoid components
Takahiro Ota, Seiji Niho, Keisuke Kirita, Genichiro Ishii, Masahiro Tsuboi, Koichi Goto DOI: 10.1002/rcr2.477
We describe two patients with advanced non-small-cell lung cancer (NSCLC), including one in whom the definitive diagnosis of pulmonary pleomorphic carcinoma (PPC) was made by histopathology of the resected tumour and another in whom the diagnosis of "favor adenocarcinoma containing sarcomatoid components" was made by tissue biopsy. Both were resistant to first line platinum-based chemotherapy, but responded dramatically to second line nivolumab therapy. |
Erratic coil migration in the bronchus after bronchial artery embolization
Hideo Ishikawa, Naoki Omachi, Misaki Ryuge, Jun Takafuji, Masahiko Hara DOI: 10.1002/rcr2.478
We report two cases of erratic coil migration from the bronchial artery to the bronchus after bronchial artery embolization (BAE). Coil migration to the bronchus is an infrequent late-stage complication of super-selective bronchial artery coil embolization, and only one other case has been reported. We propose treatment strategies and speculate on the mechanism of fistula formation. |
Computed tomography imaging-based observation of the aggressive growth of angiosarcoma: a case study
Sousuke Kubo, Nobuaki Kobayashi, Ayami Kaneko, Hiroko Aiko, Makoto Kudo, Takeshi Kaneko DOI: 10.1002/rcr2.479
Here, we report a case of pyothorax-associated angiosarcoma. Our patient had computed tomography (CT) scans of the chest annually to monitor chronic empyema, and to screen for cancers. Our patient was diagnosed with angiosarcoma within a month period after complaining of chest pain. This is the very first report on angiosarcoma whose aggressive growth could be observed on CT imaging. |
Primary pleural synovial sarcoma with repeated resection leading to long-term survival
Naoko Katsurada, Hisashi Ohnishi, Miho Ikeda, Naoe Jimbo, Yukihisa Hatakeyama, Kayoko Okamura DOI: 10.1002/rcr2.480
Synovial sarcoma is a soft tissue malignant tumour that mainly occurs in extremities. Primary pleural synovial sarcoma is extremely uncommon; thus, its therapeutic strategy has not been clearly established. Here, we report the case of a patient with primary pleural synovial sarcoma who had repeated surgery for ipsilateral pleural recurrent lesions and remains alive 12 years after the initial surgery. |
Schwannoma arising in mediastinal lymph node diagnosed by endobronchial ultrasound
Lae Hyung Kang, Dong Hoon Shin, Seong-Hoon Yoon DOI: 10.1002/rcr2.481
We report a rare case of schwannoma arising in mediastinal lymph node diagnosed by endobronchial ultrasound. |
A rare case of acute respiratory distress syndrome caused by use of gadolinium-based magnetic resonance imaging contrast media
Yi Lee, Tzu Yi Chung, Hsu-Chung Liu DOI: 10.1002/rcr2.483
Here, we present a Taiwanese woman who developed acute respiratory distress syndrome after the use of gadolinium-based magnetic resonance imaging contrast media and had a successful treatment with steroids and bilevel positive airway pressure ventilation. |
An unexpected zoonosis: pulmonary dirofilaria infection mimicking pulmonary neoplasm
Gordon Maxwell, Jaideep Sood, Stephen Allpress DOI: 10.1002/rcr2.484
Pulmonary dirofilaria infection is a rare condition in Australasia. We describe a case with radiographic findings concerning for pulmonary malignancy, with the unexpected pathological diagnosis of dirofilarial infection. |
Therapeutic bronchoscopy in a lung abscess secondary to broncholithiasis
Yoshihiro Amano, Xuexia Tong, Kiyotaka Miura, Yukari Tsubata, Noriaki Kurimoto, Takeshi Isobe DOI: 10.1002/rcr2.487
Broncholithiasis is a condition in which calcified material (a broncholith) is present within a bronchus or a cavity communicating with a bronchus. We report a case of a 60-year-old woman who developed a pulmonary abscess due to broncholithiasis and was treated by bronchoscopic broncholithectomy using a balloon catheter after antibiotic administration. |

We report the case of a 79-year-old male patient with thymoma developing with unusual invasion into the oesophageal lumen. |
