Imaging

Those who care for patients with pulmonary, critical care or sleep disorders rely heavily on chest radiology and pathology to determine diagnoses. The Southwest Journal of Pulmonary, Critical Care & Sleep publishes case-based articles with characteristic chest imaging and related pathology.

The editor of this section will oversee and coordinate the publication of a core of the most important chest imaging topics. In doing so, they encourage the submission of unsolicited manuscripts. It cannot be overemphasized that both radiologic and pathologic images must be of excellent quality. As a rule, 600 DPI is sufficient for radiographic and pathologic images. Taking pictures of plain chest radiographs and CT scans with a digital camera is strongly discouraged. The figures should be cited in the text and numbered consecutively. The stain used for pathology specimens and magnification should be mentioned in the figure legend.

Medical Image of the Week: Abdominal Compartment Syndrome Due to Massive Upper Gastrointestinal Hemorrhage

Figure 1. Coronal section demonstrating a section of the Minnesota Tube within the stomach (yellow arrow), severe dilatation of the stomach (green arrow) and small bowel (blue arrow) due to intraluminal filling from blood. There is markedly reduced lungs volumes due to superior displacement of the diaphragm.

A 29 year old woman with history of a Whipple procedure for pancreatic cancer and nonalcoholic steatohepatitis cirrhosis presented with a massive upper gastrointestinal bleeding (UGIB) likely from esophageal varices and developed hemorrhagic shock.

Emergent upper endoscopy could not be performed due to hemodynamic instability. Therefore, a Minnesota Tube was placed emergently for balloon tamponade of the bleeding. A transjugular intrahepatic portosystemic shunt was also placed emergently to decrease bleeding by reducing portal pressure. By this time, the patient had received 4 liters of normal saline, 14 units of packed red blood cells, 6 units of platelets, and 4 units of fresh frozen plasma.

The Minnesota tube did control the bleeding somewhat, however, there was continued bloody drainage from the stomach port of the Minnesota tube. The patient’s abdomen became remarkably distended and was dull to percussion throughout. A CT scan of the abdomen and pelvis revealed severe dilatation of the stomach and multiple loops of small bowel filled with mixed density blood (Figures 1 and 2). Intraabdominal bladder pressure was elevated to 34 mmHg. Given the radiographic findings, elevated bladder pressures, worsening lactic acid level and renal function, the patient was diagnosed with abdominal compartment syndrome. She was not a surgical candidate due to her grim prognosis. A large bore tube was placed into the abdominal cavity to drain ascitic fluid in effort to relieve the abdominal pressure.

Aggressive resuscitation including fluids, blood products, and four vasopressors was continued for the next several hours. However, due to patient’s poor prognosis, a decision was made to proceed with comfort care and the patient shortly passed away.

Acute upper gastrointestinal bleeding is a frequently encountered condition in the intensive care unit . Initial management generally consists of airway protection, intravascular resuscitation, correction of any coagulopathies, and acid-suppressive therapy (1). For UGIB with hemodynamic compromise, immediate upper endoscopic evaluation is indicated. The upper endoscopy allows for determination of the specific etiology of UGIB and for interventional therapy. If endoscopy cannot be done, bleeding cannot be controlled with endoscopic interventions or the patient is hemodynamically unstable, balloon tamponade should be considered (2). It is important to note that balloon tamponade is considered a bridge to more definitive therapy. Lastly, a multidisciplinary approach for management of massive UGIB should always be utilized especially in difficult cases.

Medical Image of the Week: Massive Spontaneous Intra-Abdominal Bleeding

Figure 1. CT scan of the abdomen and pelvis showing diffuse intra-abdominal bleeding.

A 67 year-old female with RA, on anti-TNF and steroids, was admitted to the ICU with severe shock, likely hemorrhagic. She was on Coumadin for atrial fibrillation. She was found to have severe coagulopathy and diffuse spontaneous abdominal bleeding (Figure 1). She also developed left popliteal artery thrombosis, with compartment syndrome requiring surgical intervention. DIC was the final diagnosis.

A 41-year-old African American woman with a history of diffuse large B cell lymphoma in remission was admitted to the hospital with severe dyspnea and abdominal pain. Recent imaging revealed extensive pulmonary and liver nodules with significant mediastinal lymphadenopathy (Figures 1 and 2).  She had an extensive outpatient evaluation of these abnormalities including multiple percutaneous and endoscopic biopsies which were nondiagnostic.  She deteriorated clinically and a ferritin level was elevated at 36,284 ng/mL.  Due to the markedly elevated ferritin, a bone marrow biopsy was performed and was normocellular with trilineage hematopoiesis and erythrophagocytosis consistent with hemophagocytic lymphohistiocytosis (HLH, Figure 3).  A VATS guided lung biopsy was performed revealing recurrence of the diffuse large B cell lymphoma (Figure 4).  She started chemotherapy with the E-SHAP (etoposide, methylprednisolone, cytarabine, cisplatin), however, became severely pancytopenic and developed acute respiratory failure, shock and multi-organ failure.  She died despite aggressive care in the intensive care unit.  Patients with HLH often present with sepsis like symptoms and multiorgan failure.  Measurement of serum ferritin level is a critical test in suggesting the diagnosis once infection is excluded.  Early recognition and prompt treatment is essential to preventing fatal outcomes.
