Overview

Hamartomas must be differentiated from other diseases that result on fat containing lesions such as lipomas and metastases.

Differentiating Hamartoma from other Diseases

Hypothalamic hamartomas

  • The differential diagnosis is broadly that of suprasellar and hypothalamic lesions, although the imaging characteristics of hypothalamic hamartomas significantly reduces the differential.
  • Hypothalamic-chiasmatic glioma is the main differential.
  • Most other lesions encountered in the region either have markedly different signal intensity or demonstrate enhancement on MRI.[1]
  • The table below summarizes the findings that differentiate hypothalamic hamartoma from other conditions that are also suprasellar and hypothalamic lesions. [2]
Disease Findings
Hypothalamic-chiasmatic glioma
  • Hypothalamic-optochiasmatic gliomas are a subset of astrocytic tumours which have tendency to occur in patients with neurofibromatosis type 1
  • These may involve the optic nerves, the optic chiasm, and the optic tracts
  • Between 20 and 50% of patients with hypothalamic gliomas have a positive family history of von Recklinghausen disease (NF-1)
Craniopharyngioma
  • Craniopharyngioma is a type of brain tumor derived from pituitary gland embryonic tissue
  • Occurs most commonly in children but also in men and women between 50 -60 years of age
  • Symptoms may present with bitemporal inferior quadrantanopia leading to bitemporal hemianopia, as the tumor may compress the optic chiasm
Rathke's cleft cyst
  • Rathke's cleft cyst is a benign growth found on the pituitary gland in the brain, specifically a fluid-filled cyst in the posterior portion of the anterior pituitary gland
  • Rathke's cleft cyst occurs when the Rathke's pouch does not develop properly and ranges in size from 2 to 40mm in diameter
  • Asymptomatic cysts are commonly detected during autopsies in 2 - 26% of individuals who have died of unrelated causes
  • Females are twice as likely as males to develop a cyst
Pituitary macroadenoma
  • Pituitary macroadenoma is a common pituitary gland tumor
  • Patients with pituitary adenoma may progress to develop lethargy, headache, nausea, and vomiting
  • Common complications of pituitary adenoma include bitemporal hemianopia, anosmia, acromegaly, and gigantism

Pulmonary hamartomas

  • The differential is dependent on whether fat or calcification is identifiable within the lesion. If fat is visualized then the differential is narrow, with almost all cases representing pulmonary hamartoma.
  • The presence of calcification also significantly narrows the differential, but to a lesser degree.
  • If neither fat, nor calcification is present, then the differential is that of a solitary pulmonary nodule and is significantly broader.
  • The table below summarizes the findings that differentiate pulmonary hamartoma from other conditions that cause a fat containing solitary pulmonary nodule.
Disease Findings
Lipoma
  • Lipoma is a fat exclusive, well circumcised mass
  • Lipomas are likely to have been present for many years, and may change size with weight fluctuation
  • These can also be an incidental finding
  • In 5-15% of patients lipomas are multiple, and approximately a third of these will be familial[1]
Myelolipoma
  • Myelolipoma is a very rare, benign pulmonary lesion, usually presenting as an asymptomatic pulmonary nodule
  • Myelolipoma is mainly composed of mature adipose tissue and normal hematopoietic cells.[3]
Metastatic disease
  • Pulmonary metastases are common and usually asymptomatic, with constitutional symptoms relating to disseminated metastatic disease and those attributable to the primary tumour dominating
  • Common symptoms include hemoptysis and pneumothorax
  • Pulmonary metastases tend to be single or multiple[1]
Pulmonary Chondroma
  • Pulmonary chondromas are usually associated with Carney’s triad
  • On CT scan, chondromas appear as smoothly marginated, round, or slightly lobulated, small areas of fat
  • Pulmonary chondromas are common in adolescents or young adults[4]

Heart

  • The table below summarizes the findings that differentiate cardiac hamartoma from other conditions that cause a fat containing lesion within the striated muscle of the heart.
Disease Findings
Hibernoma
  • Hibernoma is a benign neoplasm of vestigial brown fat
  • The majority of patients present with a slow-growing, painless, solitary mass, usually of the subcutaneous tissues
  • It is much less frequently noted in the intramuscular tissue. It is not uncommon for symptoms to be present for years
  • In general, imaging studies show a well-defined, heterogeneous mass, usually showing a mass which is hypointense to subcutaneous fat on magnetic resonance T1-weight images. Serpentine, thin, low signal bands (septations or vessels) are often seen throughout the tumor
Metastasis

Spleen, kidneys and vascular organs

  • The table below summarizes the findings that differentiate spleen, kidneys and vascular organs from other conditions that cause a incidental findings that resemble hamartoma.
Disease Findings
Splenic hemangioma
  • Splenic hemangiomas, are considered the second most common focal lesion on the spleen
  • Most hemangiomas tend to be discovered in adults from mid-30s to mid-50s years of age
  • They may be associated with splenomegaly, abdominal pain, dyspnea,and diarrhea.[6]
Retroperitoneal liposarcoma
  • Retroperitoneal liposarcoma is the most common primary retroperitoneal neoplasm
  • Retroperitoneal liposarcoma is a subtype of liposarcoma, a malignant tumour of mesenchymal origin that may arise in any fat-containing region of the body
Adrenal myelolipoma
  • Adrenolipomas are rare benign neoplasms that histologically consist of fat and bone marrow in varying proportions
  • In general, most tumors are unilateral, they show no predilection to one peculiar side. Symptoms of adrenolipoma include abdominal pain, haematuria, and abdominal fullness
  • They are rich in adipose tissue and hematopoietic elements
  • Most lesions are small and asymptomatic
  • Adrenolipomas are usually detected incidentally in autopsy or by imaging studies performed for other reasons
