Recognizing that EMH may present as an epidural or paraspinal lesion is important since chemotherapy and radiotherapy are effective therapeutic options in the majority of patients who suffer few if any symptoms. [ncbi.nlm.nih.gov]

• Splenomegaly

  These findings thus challenge our understanding of splenomegaly as a marker of disease. [ncbi.nlm.nih.gov]

  1 Splenomegaly, in particular, is the result of extramedullary hematopoiesis. [haematologica.org]

  Pseudotumoral masses as large as 12 cm in size have been described. 3 Associated splenomegaly was found in almost all the cases. [tropicalgastro.com]

• Epigastric Pain

  We report a 64-year-old man with epigastric pain of 3-months' duration radiated to the back. Imaging workup showed multiple paravertebral, retrosternal and presacral masses. [ncbi.nlm.nih.gov]

• Hepatosplenomegaly

  It is characterized by bone marrow fibrosis, extramedullary hematopoiesis with hepatosplenomegaly and leukoerythroblastosis in the peripheral blood. [ncbi.nlm.nih.gov]

  If extramedullary hematopoiesis develops, the liver and spleen become enlarged, a condition known as hepatosplenomegaly. Physical evidence of hepatosplenomegaly will be an individual who looks puffy and protrusive in the left upper abdominal area. [guwsmedical.info]

  The usual manifestations of EMH include hepatosplenomegaly due to resumed red blood cell synthesis and loss of filtering capacity in the spleen and liver [ 2 ]. [omicsonline.org]

  There was hepatosplenomegaly. A large hypodense lesion was seen in the spleen (Figure 3). The diagnosis of EMH was confirmed by fine-needle biopsy of the paraspinal masses. [appliedradiology.com]

  Physical examination revealed a thin woman without lymphadenopathy, clear breath sounds bilaterally and hepatomegaly (10 cm below the costal margin). [oapublishinglondon.com]

  On examination, he had pallor, jaundice, malar prominence; frontal bossing, splenomegaly (18 cm), and hepatomegaly (6 cm). [ijpmonline.org]

• Quadriplegia

  Paraplegia or quadriplegia may ensue. [3] MRI is the diagnostic procedure which shows isointense lobulated mass lesions seen in both T 1 and T 2 weighted imaging involving extradural portion of spinal canal and in paravertebral portions. [asianjns.org]

Imaging workup showed multiple paravertebral, retrosternal and presacral masses. Cytology findings obtained by CT-guided FNAC were compatible with the diagnosis of EMH. Peripheral blood smear confirmed the presence of β-thalassemia. [ncbi.nlm.nih.gov]

Thorough and systematic preoperative workup is essential before treatment planning. [oapublishinglondon.com]

• Ground Glass Appearance

  glass appearance, effusions, septal thickening on chest computerized tomography have been also described in PMF patients. 4 In patients with intermediate/high risk myelofibrosis, 5 allogeneic hematopoietic stem cell transplant (HSCT) is the only known [haematologica.org]

• Visceromegaly

  Visceromegaly is best evaluated with ultrasound, CT or MRI. Lesions are typically hypermetabolic and are FDG-18 avid on PET-CT 4. [radiopaedia.org]

In the English literature, there are a few cases with intracranial EH and thalassemia, which were treated with different treatment modalities, with different outcomes. There is no standard treatment approach in patients with symptomatic EH. [ncbi.nlm.nih.gov]

It is essential to distinguish EMH from other extradural central nervous system tumors, because treatment and prognosis are totally different. [ncbi.nlm.nih.gov]

Prognosis The median length of survival for patients with primary myelofibrosis is 3.5-5.5 years. The 5-year survival rate is about half of that expected for age- and sex-matched controls. [emedicine.medscape.com]

Otolaryngologists should consider this etiology in patients with chronic anemia and conductive hearing loss in the absence of otitis media. [ncbi.nlm.nih.gov]

Due to the limited size of the nodules and the lack of symptoms suggestive of an infectious etiology, in 2 patients biopsy was not performed. [haematologica.org]

However, exposure to radiation, Thorotrast contrast agents, and industrial solvents (eg, benzene, toluene) have been associated with an increased risk. [10, 11, 12, 13] Epidemiology Primary myelofibrosis is an uncommon disease, with an annual incidence [emedicine.medscape.com]

The current pathophysiology suggests that sacral fractures release hematopoietic stem cells, which in turn replicate to form an EMH mass. [ncbi.nlm.nih.gov]

This pathophysiologic mechanism is not related to the amount of the tumour since small, early-stage solid tumours have been associated with extramedullary haematopoiesis [ 5 ]. [oapublishinglondon.com]

Pathophysiology In patients with primary myelofibrosis, the hematopoietic system is most affected. Other organ systems may be involved via extramedullary hematopoiesis. (See the image below.) [emedicine.medscape.com]

The patient had not received preventive local chest radiation. Ten years later, he suffered from a life-threatening hemothorax complicated by acute respiratory failure without traumatic history. [ncbi.nlm.nih.gov]

We observed that loss of ATG5 in B cells significantly increased the survival of TLR7 tg mice, reduced serum IgG and anti-nuclear autoantibodies, thereby preventing glomerulonephritis. [jimmunol.org]
