A RealICU Clinical Challenge – Lesions in the Brain and Lungs.

brain lesion
multiple pulmonary nodules

59 year old male with a history of non-ischemic cardiomyopathy, status post AICD/pacemaker insertion, presented with generalized weakness and confusion. He was diagnosed with diffuse B-cell lymphoma and underwent bone marrow transplant about a year ago.

The patient was on Warfarin (Coumadin) for his cardiomyopathy. Three days prior to admission he fell in the bathroom and hit his head. On presentation to the Hospital his INR was elevated at 4.1 with the platelet count of 17,000 (normal>150,000). He had low grade fever and normal white count. Cultures were obtained.

CT head showed a lesion in the right frontal area. MRI is not possible due to the AICD. CT Chest revealed multiple pulmonary nodules (see the image above).

The patient is a farmer and was working with hay several days prior to admission. He was started on an antifungal agent (voriconazole) for possible fungal infection. Bronchoscopy and biopsy was scheduled.

What is the likely etiology of the lesion in the brain and in his lungs?

An Explosive Cancer Presentation

multiple abdominal masses
multiple pulmonary nodules

This is the most unusual and bizarre cancer case I have ever seen.

69 year old female with no previous medical history presented to her gynecologist with vaginal bleeding. Pelvic ultrasound reveled an abnormal endometrial thickening. Endometrial biopsy confirmed the diagnosis of endometrial cancer.

The patient underwent uneventful laparoscopic hysterectomy and salpingo-oophorectomy. The post-op pathology revealed a surprise – in addition to the endometrial cancer the patient also had grade 1 ovarian papillary serous carcinoma.

A PET scan revealed areas of increased intake in the pelvis. Very shortly after the first surgery she underwent exploratory laparotomy and restaging including pelvic/periaortic lymphadenectomy, omentectomy and multiple biopsies. The final pathology – no cancer, just reactive changes after the first procedure.

Five weeks later the patient gets readmitted with abdominal distention and a sepsis like picture. CT abdomen/pelvis showed multiple abdominal and pelvic masses. CT chest shows multiple pulmonary nodules (see the images above). Broad spectrum IV antibiotics started. The patient was getting progressively worse.

The biggest question was: what were we dealing with? It would be unlikely for stage 1 endometrial or ovarian cancer to progress so rapidly just a few weeks after a complete restaging.

Some reports in the medical literature indicate that a laparoscopic approach for hysterectomy could promote retrograde dissemination of the cancer cells through the fallopian tubes into the peritoneal cavity. These concerns were not substantiated in the bigger studies.

The patient was taken back to OR for an exploratory laparotomy. Intraoperative findings – abdomen and pelvis are packed with cancer. The preliminary pathology – high grade sarcoma. The biopsy specimens were sent to New York to a sarcoma specialist.

The patient continued to deteriorate and Hospice care was initiated.

All the pathology slides beginning with the first surgery are going to be re-looked at and reviewed again. Regardless of what the final pathological diagnosis is, this is the most explosive presentation of cancer I have ever seen.

Distance from the Hospital Could Be the Biggest Risk Factor in a Medical Emergency

T6 epidural mass

There are very few oncologic emergencies. Neoplastic epidural spinal cord compression is one of them. The delay in diagnosis and treatment is often explained by the non-specific nature of the presenting signs and symptoms.

The patient developed urinary retention a couple of weeks prior to presentation. On the morning of admission he was fully functional. Later he sat down to have a cup of coffee and boom – he couldn’t feel his legs. He couldn’t get up either.

Ideally, this patient should be rushed to the Hospital with an emergent neurosurgery consult. Prompt surgical decompression of the spinal cord or radiation treatment could improve his chances for functional recovery.

The patient lives on a 500 acre farm in a remote part of the country and getting to the closest ER took some time. It did not take the ER physician a long time to recognize the potential problem. Intravenous steroids were administered. MRI of the spine clearly showed an epidural mass with spinal cord compression at T6 level (see the image above).

No neurosurgeon was available in the small outlying hospital. That means that the patient had to be transferred to a bigger hospital. More time spent on arranging the transfer and getting the patient to the neurosurgeon.

All in all, it took 12 hours from the onset of symptoms to the neurosurgical evaluation. The patient had an urgent laminectomy with spinal cord decompression. The likely diagnosis is metastatic prostate cancer with T6 epidural metastasis and spinal cord compromise.

Despite the treatment with steroids and an “emergent” surgical decompression the patient remains paraplegic. His PSA is > 300. The final pathology is yet pending.

This is an unfortunate case. Despite appropriate actions and management, the patient did not receive the needed care for 12 hours after the onset of symptoms. Had he lived closer to an urban area and a bigger hospital, he might have been able to walk.

This is true not only for trauma and oncology patients. Same goes for the patients with coronary conditions and other emergencies. The unfortunate truth is that access to medical care often decreases the further you go from a major urban center.

We have come a long way since the old days when ground ambulance was the only way to transport critically ill patients. Helicopters and fixed-wing aircrafts are readily available now for transfer.

Everything takes time, though. Packing the patient for the ambulance ride or even picking up the phone and waiting for the answer on the other end wastes the precious time that could make a big difference in the patient’s outcome. The bottom line is - in the case of a medical emergency the distance from the Hospital could be a deciding factor between life and death.

Pathological Fractures

Pathological Fractures

According to the “rule of pairs” odd and unusual things often come in pairs. It has been a few years since I saw a pathological fracture and now I have two patients coming with it on the same week.

The two images above are, actually, images of the two different patients. The upper image shows a pathological fracture of the left clavicle due to multiple myeloma. The patient came to her physician complaining on a shoulder pain. There was no history of injury or trauma. Shoulder XR revealed clavicular pathological fracture. No surgical treatment was necessary.

The bottom image shows fracture of the distal femur due to…multiple myeloma. The patient came to the Emergency Room with an excruciating pain in the leg. This fracture will require rodding.

Lung Cancer

Lung Cancer on the Chest XR

The patient presented to his PCP complaining of shortness of breath and cough. Chest XR revealed large left-sided lung mass. CT guided mass biopsy confirmed the diagnosis of poorly differentiated adenocarcinoma. Oncology service was consulted.

Large Abdominal Mass

large abdominal mass

39 year old male with no previous medical history, presented with a vague abdominal pain, distention, weight loss (50Lbs over 3 months) and night sweats. CT scan of his abdomen revealed multiple large masses. The largest mass was 12cm in diameter and was arising form the root of the mesentery (see image above). One of the masses was encroaching on the superior mesenteric artery. The patient was scheduled for laparoscopic biopsy to obtain a tissue sample. He was suspected to have abdominal lymphoma.

Metastatic Colon Cancer

metastatic colon cancer

An elderly male with history of recently resected colon cancer presented with jaundice. His CT findings are above. He elected to go home with Hospice in lieu of pursuing any invasive diagnostic or palliative measures.

Renal Cell Cancer

Renal Cell Cancer

Renal Cell Cancer

Renal Cell Cancer (RCC) constitutes 85% of the primary renal neoplasms. Many patients are asymptomatic until the disease is advanced.

Symptoms of RCC
The classic triad of RCC consists of flank pain, hematuria, and palpable abdominal mass. (Now rare at presentation)
Patients could also have scrotal varicoceles and inferior vena cava (IVC) involvement. IVC involvement can lead to lower extremity edema, ascites, hepatic dysfunction and even pulmonary embolism.

Many patients eventually develop a paraneoplastic syndrome (systemic symptoms due to ectopic production of various hormones including erythropoietin, parathyroid hormone-related protein, gonadotropins, ACTH-like substance, glucagon and insulin) .
Other manifestations of RCC may include:

Anemia (low blood counts) – quite common and can be severe.

Hepatic dysfunction – is uncommon

Fever, night sweats, anorexia, weight loss

Hypercalcemia (high serum calcium) – could be due to bone metastasis or due to systemic effects of various hormones.

Some patients also present with AA amyloidosis, thrombocytosis and polymyalgia rheumatica.

Diagnosis
The diagnostic evaluation is initiated by ordering CT abdomen or kidney ultrasound. Metastatic disease should be excluded after the presence of the renal mass is confirmed,

Treatment
Surgery is curative in the majority of patients without metastatic RCC.
Chemotherapy, immunotherapy and radiation therapy are offered for the metastatic disease.

Patient with metastatic breast cancer

left-sided pneumonia

79 year old female with stage 4 metastatic breast cancer and poor prognosis presented with progressively worsening shortness of breath. Chest XR revealed evidence of left-sided pneumonia with lung consolidation(click on image above). The patient requested a "full code" including intubation.
