The past and present clinical history of 13 patients with hemodynamic and angiographic diagnosis of chronic thromboembolic pulmonary hypertension (CTPH) was reviewed in order to investigate the reasons for failure of resolution of acute pulmonary embolism (PE) and findings useful for diagnosis of CTPH. All patients had chest radiograph, ECG, arterial blood gas analysis and pulmonary perfusion scintigraphy performed. Clinical assessment demonstrated that no patient had diagnosis and treatment of the several retrospectively identified episodes of PE (from 1 to 8); the lack of diagnosis was due to underestimation of symptoms and signs such as dyspnea (85%), pleuritic chest pain (31%) or phlebitis (46%) that were present months or years earlier. Alternative diagnoses erroneously made were dyspnea of unknown origin (5 cases), left heart failure (4 instances) and pneumonia (2 cases). Once CTPH has developed, chronic dyspnea (92%) and substernal chest pain (100%) are almost always present: chest radiograph and ECG show signs of chronic hypertension such as enlargement of hila (100%), right heart sections (77%), azygos vein (46%) and P pulmonale (67%), T inversion on right precordial leads (75%), S-T segment depression (75%), respectively. Perfusion scintigraphy shows severe perfusion impairment (55.7% of the total vascular bed) paralleled by severe hypoxia (standard PaO2 = 49 +/- 14.1 mm Hg). In conclusion, patients with PE who develop CTPH are not diagnosed and thus untreated because clinical symptoms and signs of acute PE have not been recognized. If CTPH develops, clinical assessment (including simple and noninvasive techniques such as chest radiograph, ECG and blood gas analysis) may show a quite characteristic pattern useful for diagnosis.

A 43-year-old white man with a history of cigarette smoking, hypertension, nephrolithiasis, and cervical degenerative arthritis was hospitalized for sudden-onset severe, substernal, and pleuritic chest pain with epigastric radiation. Despite evaluation, the cause remained unclear and the patient expired on hospital day 5. Autopsy revealed acute Stanford type A aortic dissection, hemopericardium, and hemothorax. Grossly, the aorta and its branches, including uninvolved medium-sized arteries, displayed extreme mural fragility. Microscopic examination showed a primary lymphoplasmacytic aortitis-periaortitis without giant cells. Rents within the tunica media, medial-adventitial inflammation, and elastic fiber disruption were limited to sites of gross aortic dissection. Muscular arteries showed patchy, chronic arteritis-periarteritis without giant cell infiltrate or aneurysm formation. This case documents an unusual association of primary lymphoplasmacytic aortitis and aortic dissection.

A 22-year-old African American female patient presented with a sudden onset of difficulty in breathing for approximately 2 days accompanied by bilateral pleuritic chest pain. Her past medical history was significant for tuberous sclerosis and mental retardation. Preliminary radiographic imaging showed bilateral pneumothoraces for which bilateral chest tubes were subsequently inserted. A computed tomography scan of the chest showed cystic changes compatible with lymphangioleiomyomytosis (LAM). She underwent a video-assisted thoracoscopy with pleurodesis and an open lung biopsy for the confirmation of the diagnosis. Cystic changes involving the visceral pleura were noticed during the procedure. Understanding that "tuberous sclerosis complex" is an illness that could be associated with LAM should prompt clinicians to consider the diagnosis if the patients present with shortness of breath, pneumothorax, diffuse cystic lung changes, or hemoptysis. Hemoptysis results from pulmonary venous hypertension, which is a consequence of LAM. Pleuroscopy or video-assisted thoracoscopy may show unusual findings, as described in this case, which could be pathognomonic for the diagnosis.

Ectopic breast is defined as the presence of breast tissue outside the pectoral region. In this article, we are reporting an extremely rare case of pulmonary aberrant breast tissue. A 79-years-old Caucasian woman with the history of hypertension, diabetes mellitus and ischemic heart disease, presented to the emergency department for worsening dyspnea on exertion and pleuritic chest pain over the last few days. Both thoracic CT scan and the gross evaluation of tumor after its removal by thoracotomy were in favor of a soft tissue tumor such as pulmonary lipoma, whilst surprisingly the histological examinations revealed the mass to be ectopic breast tissue. Although it is extremely rare, this diagnosis should be considered in the evaluation of pulmonary masses.

Post-infectious glomerulonephritis (PIGN) usually occurs within few days to weeks following an infection. Clinical presentation is variable, but in general, it is considered a benign entity with good prognosis. It rarely requires kidney biopsy to confirm the diagnosis. We present a case of a 55-year-old, previously healthy, male who presented for worsening shortness of breath, persistent cough, and right-sided pleuritic chest pain. Initial workup revealed a right exudative effusion with empyema. Hospital course was complicated by acute kidney injury requiring renal replacement therapy with a peak creatinine of 10.2 mg/dL from a baseline of 1.18 mg/dL. On kidney biopsy, findings were compatible with a diagnosis of cryoglobulinemic glomerulonephritis or an atypical form of PIGN. While a wide variety of histopathological findings on renal biopsies have been described to complement the usual diffuse proliferative glomerulonephritis pattern, cryoglobulinemic features with negative cryoglobulin have never been reported. Our case is unique not only by having an atypical histological presentation but also by meeting the criteria of atypical PIGN with persistent hypertension and microscopic hematuria.

A 59-year-old male with a history of nonobstructive coronary artery disease, diabetes mellitus, hypertension, and prostate cancer presented to the hospital with 1-day history of pleuritic chest pain. Initial workup for acute coronary event was unremarkable. Chest X-ray revealed multiple small radial densities which were linear and hyperdense, consistent with embolization of metallic seeds to the pulmonary circulation. The patient was noted to have had radioactive metallic seeds implanted for prostate cancer 6 months ago. Diagnosis of pulmonary embolization of prostatic seeds is challenging as they frequently present with chest pain mimicking acute coronary syndromes.

A 62-year-old man presented to the Emergency Department with dyspnoea and central pleuritic chest pain radiating posteriorly to between the scapulae. His medical history included hypertension, osteoporosis and chronic kidney disease secondary to focal segmental glomerulosclerosis with relapsing nephrotic syndrome. Significant examination findings included a loud palpable P2 and a displaced apex beat. An ECG revealed sinus tachycardia with a right-bundle branch block and p-pulmonale. A CT pulmonary angiogram and aortogram demonstrated extensive bilateral pulmonary emboli and a descending thoracic aortic dissection. Subsequent ultrasound of the lower limbs confirmed an extensive, non-occlusive deep vein thrombosis in the right calf. Management of this patient involved therapeutic anticoagulation and tight blood pressure control, with plans for surgical repair delayed due to worsening renal impairment and subsequent supratherapeutic anticoagulation. Co-existence of an aortic dissection and PE has been rarely described and optimal management remains unclear.

Cholangiocarcinoma (CC) is the second most common primary hepatic malignancy. Although the frequency of malignancy is generally increased in chronic liver disease, CC rarely presents in Wilson disease (WD). The incidence of hepatic malignancy in WD is only 1.2%, with CC accounting for 0.5%. A 66 year old male with history of hypertension, diabetes, and compensated cryptogenic cirrhosis presented with acute onset dyspnea and pleuritic chest pain. He was incidentally found to have a sizeable mass in the right hepatic lobe. Ultimately, a liver biopsy revealed dense demoplasia and increased mucin production, consistent with diagnosis of CC. Biopsy also demonstrated increased copper deposition consistent with WD, explaining the patient's underlying cirrhosis. Unlike other forms of chronic liver disease where incidence of liver cancer is increased, the lower rate of malignancy seen in WD may be explained by a protective effect of copper in WD. Copper acts to both directly stabilize DNA and inhibit angiogenesis. In this case, it is possible that the degree of copper deposition in his liver was mild, causing cirrhosis and the chronic liver inflammation that caused his CC. However, it may not have been sufficient to "protect" against development of CC.

BACKGROUND Severe acute respiratory syndrome coronavirus 2, the virus responsible for Coronavirus Disease 2019 (COVID-19), has infected more than 8 million people worldwide and placed massive strains on healthcare systems around the world. Although classically causing cough, fever, and shortness of breath, increasing evidence suggests that manifestations of COVID-19 can be more subtle or masquerade as other clinical entities. CASE REPORT A 48-year-old man with hypertension and type 2 diabetes mellitus presented to the Emergency Department with acute-onset pleuritic chest pain that had developed 1 day earlier and was found to be hypoxemic, requiring supplemental oxygen. He was admitted under the internal medicine service and underwent an extensive workup for his chest pain and hypoxemia, including a negative computed tomography scan with pulmonary embolism protocol, negative nuclear medicine ventilation/perfusion scan, normal electrocardiogram, and normal echocardiography. In the end, he was diagnosed with viral pleuritis as the diagnosis of exclusion. Our patient subsequently developed a fever and shortness of breath and his nasopharyngeal swab performed on admission to hospital returned positive for COVID-19. The patient's pleuritic pain and oxygen requirements improved with supportive management over the next several days. CONCLUSIONS I report a patient who experienced pleuritic chest pain from viral pleurisy that was the initial manifestation of COVID-19 which, to the best of my knowledge, has not yet been reported in the literature. This case report further emphasizes that COVID-19 may present with atypical symptoms. It is crucial to be aware of these atypical presentations of COVID-19 so that patients are appropriately identified, isolated, and treated, while protecting health care workers from exposure.
