“…In a report of two cases, there were no symptoms in children and one episode of seizure without a neurological deficit in adults [12]. The differential diagnoses include calcified epidural hematoma, calcified subdural empyema, meningioma, calcified arachnoid cyst [6,7,13], and rarely plasmacytoma or a tumor mass composed of myeloma cells [ 14,15]. One recent report says that the ossified chronic subdural hematoma should be considered a differential diagnosis when encountering an intracranial placeholder [16].…”

Calcified subdural hematoma (CSDH) is a very rare presentation but a known and reported entity in literature. Most of the case reports have been described in children and the elderly. Surgical treatment for CSDH is still considered controversial. We report here a case of calcified subdural hematoma in a middleaged male that was successfully operated on. A 45-year-old male presented with complaints of right-sided weakness and seizures with a history of head trauma three years ago. Non-contrast computerized tomography (NCCT) head showed calcified subdural hematoma associated with mass effect and midline shift. A frontotemporoparietal craniotomy was done to remove the CSDH. Intra-operatively the brain was pulsating well. He was discharged on the 12th postoperative day and doing well on a follow-up visit.

“…Plasmacytoma incidentally discovered after a head injury is rare. Some head tumors are related to injuries, such as eosinophilic granuloma [6,7] and meningioma [8]. The skull-bone cells may undergo genetic mutation during the process of wound repair, leading to tumors over a long period of time.…”

“…If progression to MM occurs, systemic therapy like high-dose chemotherapy and autologous hematopoieticcell transplant may be administered [1]. However, patients may die during conservative treatments like radiotherapy and chemotherapy [8,10,12]. If the lesion causes structural instability or neurologic compromise, surgery may be performed [1].…”

Multiple myeloma complicated by skull plasmacytoma discovered after head injury

Plasmacytoma is a malignant tumor originating from the plasma cells of the bone marrow. Those discovered after a head injury is rare. We report a case of a 48-year-old female who complained of scalp mass without other symptoms after head injury. Meningioma was considered preoperatively based on imaging findings, and surgical resection was performed. Postoperatively, multiple myeloma complicated by skull plasmacytoma was diagnosed by histopathology and systematic examinations in succession. When evaluating a head mass that appeared after a head injury, plasmacytoma should be considered at times. Osteolytic changes and biconvex form on imaging are beneficial to differentiation.

“…In the second case, the patient was completely asymptomatic, and MRI noted dura involvement, superior sagittal sinus invasion and cerebellar tonsil displacement [ 3 ]; in our presentation, the mass did not invade the dura or displace brain parenchyma. Although scalp masses have been noted on initial presentation of multiple myeloma, patients typically present with additional symptoms, including gait disturbance [ 4 ], acute weakness, bone pain and confusion [ 5 ]. There was also a case report of incidental discovery after imaging following head trauma [ 6 ].…”

Scalp mass: an atypical presentation of multiple myeloma

A 64-year-old male with no history of trauma presented to the general surgery clinic with a 6-month history of an asymptomatic left parietal scalp mass. The differential included benign etiologies such as lipoma or sebaceous cyst. At surgery, a hemorrhagic soft tissue mass with underlying defect in the parietal calvarium was noted. The initial attempt at resection was abandoned and neurosurgical consultation was requested. Magnetic resonance imaging demonstrated an enhancing scalp mass with a lytic lesion of the parietal calvarium with no intradural extension. Craniectomy with mass resection and mesh cranioplasty were performed. Pathology confirmed plasma cell neoplasm; serum protein electrophoresis and lytic skull lesions confirmed multiple myeloma. This rare presentation of multiple myeloma serves as a call for providers to maintain a broad differential when evaluating a seemingly benign mass, consider rare etiologies when appropriate and maintain vigilance for abnormal findings during any procedure.
